1N4007GP-E3/54 — 1A/1000V Glass Passivated Standard Recovery Rectifier Diode (DO-41)

What Are the Technical Specifications of 1N4007GP-E3/54?

1N4007GP vs standard 1N4007 — the three specs where glass passivation changes the game. Same package, same pinout, same basic ratings. The differences are in the numbers that datasheets don't always emphasize — but your circuit cares about them.

What these bars mean in practice: The GP's specified 2µs t_rr means you can predict reverse recovery behavior. The standard 1N4007's t_rr is not characterized — it varies from batch to batch. In a design where reverse recovery current couples into sensitive nodes, that variability is a hidden risk. The 175°C junction rating gives you 25°C of extra thermal headroom, which matters in enclosed power supplies and automotive under-hood applications.

When Should You Use (and NOT Use) the 1N4007GP-E3/54?

✅ Use 1N4007GP-E3/54 when:

• Automotive or high-reliability rectification. AEC-Q101 qualification and 175°C T_J max make this the right call for anything that goes into a vehicle, industrial controller, or outdoor installation. The glass passivation is not a marketing term — it eliminates microscopic voids in the junction that become failure nucleation sites over thermal cycles.
• AC-DC front-end rectification where t_rr variability matters. In a LinkSwitch or TinySwitch-based design, the rectifier's reverse recovery behavior directly affects startup current. Forum reports from Power Integrations' own community confirm that switching from a generic 1N4007 to the GP version resolved field failures.
• Designs with tight leakage current budgets. At 0.1µA typical at room temperature, the GP leaks roughly 5× less than a generic 1N4007. In battery-powered equipment with a reverse-protection diode, that directly extends shelf life.
• Production lines that want one rectifier SKU across all products. The GP costs slightly more than a generic 1N4007, but standardizing on it eliminates the risk of a standard part ending up in a GP-required position. One reel, zero mix-ups.

❌ Don't use 1N4007GP-E3/54 when:

• Switching above ~5kHz. The 2µs t_rr is specified but it's still a standard recovery diode. In an SMPS output rectifier running at 65kHz+, reverse recovery losses will cook it. Use UF4007 (75ns) or ES1J (35ns SMD).
• You need the absolute lowest V_F. At 1.1V forward drop, the 1N4007GP wastes ~1.1W at 1A. For low-voltage circuits (≤24V) where every millivolt counts, a Schottky like the 1N5819 (V_F=0.45V) is the better choice — but it only blocks 40V.
• Surface-mount is non-negotiable. The GP is through-hole only. For SMD general-purpose rectification at 1000V/1A, look at S1M (SMA package, same ratings). For glass-passivated SMD, consider US1M (ultrafast, 75ns).
• Cost is the only priority and volume exceeds 100k units. At very high volumes, the price difference between GP and generic 1N4007 becomes meaningful. If your design truly doesn't care about t_rr or leakage (LED string rectification, basic transformer secondaries), the generic part saves money.

What Are the Alternatives to 1N4007GP-E3/54?

The GP sits in a sweet spot. It costs less than a UF4007, handles the same voltage and current, and gives you a specified t_rr that generic 1N4007s don't guarantee. For 50/60Hz rectification, it's arguably over-specified. For SMPS output rectification, it's too slow. But for the vast middle ground — line-frequency power supplies where you want predictable performance and field reliability — the GP is exactly the right part.

What Are the Typical Applications of 1N4007GP-E3/54?

AC mains bridge rectification (50/60Hz). Four 1N4007GPs in a bridge configuration give you a 1000V/1A rectifier that handles 230V AC with margin. The glass passivation means the reverse recovery is consistent across all four diodes — no imbalance in the bridge that could generate unexpected EMI. For most sub-10W linear and basic switching supplies, this is the default choice.

Automotive reverse-battery protection. A series diode on the input rail that blocks reverse voltage and survives load dump. The 175°C junction rating and AEC-Q101 qualification matter here — under-hood ambient can exceed 100°C, leaving only 50°C of rise for a standard 150°C part. The GP's extra 25°C of headroom is the difference between a design that passes thermal qualification and one that doesn't.

Freewheeling diode for relays and solenoids. When a relay coil de-energizes, the flyback voltage spikes until the freewheeling diode clamps it. The 1N4007GP's 1000V rating handles the worst-case inductive kickback, and the specified t_rr means the clamp activates predictably. For AC-line-powered relays and contactors, this is the standard protection diode.

Industrial power supply input protection. In 24V industrial control panels, the GP sits on the DC input as reverse-polarity protection and surge clamping. The low leakage (<0.1µA typical) means it doesn't slowly drain backup batteries. The 30A surge rating handles inrush when large capacitor banks charge through it.

Why Buy 1N4007GP-E3/54 from ICMASS?

We stock both the /54 (tape & reel, 5500 pcs) and /73 (ammo pack, 3000 pcs) variants. If you're hand-soldering prototypes, we can cut tape to your quantity. If you're running a pick-and-place line with a through-hole insertion station, the ammo pack is ready to feed. Tell us your assembly process and we'll ship the right packaging.

Cross-reference support for other GP-series diodes. If your BOM calls for 1N4004GP or 1N4006GP (lower voltage grades of the same glass-passivated family), we can help you cross-reference to the 1N4007GP — same specs, higher voltage rating, and often in stock when the lower-voltage grades are on allocation.

BOM consolidation across your rectifier line items. Many of our customers standardize on the 1N4007GP for all through-hole rectification under 1A, replacing multiple lower-voltage SKUs. One part, one reel, every general-purpose rectifier position on the board. We can quote your annual volume and hold buffer stock so you don't carry the inventory cost.

Frequently Asked Questions

Q1: What is the difference between 1N4007 and 1N4007GP?

A: The GP version uses a cavity-free glass-passivated junction instead of a standard diffused junction. This gives it a specified t_rr of 2µs (vs unspecified for standard), 175°C max junction temperature (vs 150°C), and typical leakage under 0.1µA (vs ~0.5µA). Same 1000V/1A/DO-41 ratings. The GP costs slightly more and is statistically more reliable in the field.

Q2: Can I use 1N4007GP in an SMPS output rectifier?

A: No. At 2µs t_rr, the GP is a standard recovery diode. In an SMPS switching at 65kHz (15µs period), reverse recovery alone would consume 13% of the cycle. Use a UF4007 (75ns t_rr) or ES1J (35ns, SMD) for any switching frequency above ~5kHz. The GP is designed for line-frequency rectification where t_rr doesn't matter.

Q3: Is the 1N4007GP-E3/54 RoHS compliant?

A: Yes. The E3 suffix indicates RoHS compliance per JESD 201 class 1A whisker test. The leads are matte tin plated — no lead finish compatibility issues with standard soldering processes.

Q4: What does the "/54" mean in the part number?

A: /54 = 13" tape & reel, 5500 pieces per reel. The alternative is /73 = ammo pack, 3000 pieces. The silicon inside is identical. Choose /54 for automated insertion, /73 if you're hand-stuffing boards and want the leads pre-formed.

Q5: Can I replace a 1N4007 with a 1N4007GP in an existing design?

A: Yes — drop-in replacement. Same package, same pinout, same voltage and current ratings. The GP's 2µs t_rr is close enough to a typical generic 1N4007's actual t_rr (which is usually 1–3µs anyway, just not guaranteed) that no circuit changes are needed. You get guaranteed specs and better reliability without touching the PCB.

Q6: What is the forward voltage drop of the 1N4007GP at 1A?

A: 1.1V maximum at 1A, 25°C. At lower currents, V_F decreases: roughly 0.8V at 100mA and 0.95V at 500mA. The negative temperature coefficient means V_F drops about 2mV/°C as the junction heats up — at 125°C, expect approximately 0.9V at 1A.

Q7: Is the 1N4007GP suitable for automotive applications?

A: Yes, with the HE3 suffix version. The standard 1N4007GP-E3/54 is industrial-grade. For automotive, order 1N4007GPHE3/54 — same diode, but AEC-Q101 qualified with full PPAP documentation. The 175°C T_J rating makes it viable for under-hood applications where ambient can reach 105°C.

Q8: What is the difference between Vishay's SUPERECTIFIER and a standard plastic rectifier?

A: The SUPERECTIFIER construction is Vishay's trademarked name for their glass-passivated process. Standard plastic rectifiers encapsulate the silicon die directly in epoxy, which can trap moisture and create microscopic voids at the junction surface over thermal cycles. SUPERECTIFIER parts fuse a glass layer directly onto the junction surface before epoxy molding — no voids, no moisture path, and a hermetically sealed junction inside a plastic package. It's the reliability mechanism behind the 175°C rating and the specified t_rr.

Q9: How does the 1N4007GP compare to the UF4007 for a 50/60Hz bridge rectifier?

A: For 50/60Hz, use the GP. The UF4007's 75ns t_rr adds cost you don't need at line frequency, and its higher V_F (1.7V vs 1.1V) increases conduction loss by ~55%. The GP is the right speed for the right job.

Q10: What is the surge current rating of the 1N4007GP?

A: 30A peak for an 8.3ms half-sine, 45A for a 1ms square pulse. The I²t rating for fusing is 3.7 A²s. In practice, this means the GP survives the inrush when a 100µF capacitor charges through it at power-on. If you need higher surge capability, step up to a 3A diode like the 1N5408 (200A surge, same 1000V rating).
