NCE3010S — 30V/10A N-Channel Power MOSFET (SOP-8)

What Are the Technical Specifications of NCE3010S?

Key numbers that matter: per the NCE3010S datasheet (V4.0), R_DS(on) is guaranteed at two gate voltages — 12mΩ max at 10V/10A and 16mΩ max at 4.5V/5A. The 4.5V test current is half the 10V test current, which tells you where the die's saturation curve sits.

Why does the 2.5W envelope matter? 2.5W at 50°C/W puts the junction at 150°C in a 25°C room — and that 50°C/W is the 10-second number. Real boards run 80–125°C/W steady-state, so the honest continuous budget is closer to 1W than 2.5W.

The avalanche note is honest: the datasheet says "fully characterized avalanche voltage and current" but publishes no numeric E_AS. Treat it as a margin, not a spec — for inductive loads, keep the freewheeling clamp path.

When Should You Use (and NOT Use) the NCE3010S?

✅ Use NCE3010S when:

• 5V-logic load switches. R_DS(on) is guaranteed at 4.5V, so a 5V MCU GPIO or 5V rail drives it fully enhanced. Relay, fan, solenoid, and heater switching on 12V/24V rails is the natural socket.
• Cordless tool and appliance power boards at 10-30W. 20V-max tool packs (5S, 21V charge) sit comfortably inside the 30V rating — the class leader in Shenzhen for low-side switching in compact SMD power stages (2025–2026), replacing SO-8 legacy parts at lower cost.
• UPS and power-switching circuits at moderate frequency. The datasheet's own application list — 32.5nC gate charge keeps a real driver happy into the hundreds of kHz.
• Parallel pairs for higher current. Two parts share the load with equal gate traces; the standard SO-8 pinout (pins 1-3 Source, 4 Gate, 5-8 Drain) makes the layout symmetric.
• Sockets currently running AO4496/FDS6690-class parts. Same package, same voltage/current class, and the 4.5V guarantee line matches what those parts promised.

❌ Don't use NCE3010S when:

• Driving from a 3.3V MCU GPIO. V_GS(th) runs to 3V and R_DS(on) is only specified at 4.5V and 10V — a 3.3V rail is outside the guaranteed window. Use a 2.5V-specified part or add a gate driver.
• Sustained 10A without PCB copper. 10A at 12mΩ is 1.2W of conduction loss — half the 2.5W envelope before you add switching loss. Without ≥100mm² of drain copper and thermal vias, the junction cooks.
• Raw 24V battery rails with transients. A 24V lead-acid float charge sits at 28.8V; 30V leaves under 1.2V of headroom for spikes. For 24V systems with real inductance, step to a 40V or 60V part (the NCE6008AS-class).
• High-frequency SMPS synchronous rectification. No body-diode t_rr is published, and 1550pF C_iss needs a serious driver. This is a switching part, not an SR part.
• Automotive load-dump exposure. A 40V load dump will punch through 30V — add a TVS or pick a 40V+ rated part for anything near the alternator.

What Are the Alternatives to NCE3010S?

The 30V SOP-8 decision in one line: the 3010S sits at the 10A entry point of the NCE 30V family — the 3015S and 3018AS are the same package and pinout with bigger dies, and the drop-in check is the R_DS(on) number at your actual gate voltage.

Here's the thing to check before substitution: the gate-drive row. A part that only specifies 10V (like the 60V NCE6008AS) is not a drop-in for a 4.5V-specified socket — the 3010S is, because its 4.5V row matches the legacy logic-level parts.

From what we see in Shenzhen (2025–2026), 30V SO-8 sockets that started on AO4496 or FDS6690 migrate to domestic parts like this for cost.

The migration fails most often when the new part is driven at the old part's gate voltage without checking the R_DS(on) row. Same pinout, different guarantee.

What Are the Typical Applications of NCE3010S?

5V-logic low-side switching in appliances: A 5V MCU rail switches a 12V relay or fan through the 3010S — the 4.5V guarantee is the whole point, and conduction loss at 1-2A is under 50mW.

20V-max cordless tool and appliance boards: The workhorse low-side switch in compact SMD power stages (2025–2026 Shenzhen market). 5S tool packs charge to 21V — well inside the 30V rating with the body diode handling the commutating path.

UPS power-switching sections: The datasheet lists UPS as a target application. 32.5nC gate charge and 100ns max turn-off delay keep the drive stage simple on inverter boards.

Battery protection and load-switch paths: Low on-resistance keeps the voltage drop small on the discharge path; the 50A pulse rating covers short-circuit and hot-plug transients inside the SO-8 lead frame's limits.

LED driver and solar-bank switching stages: Constant-current stages switching at tens of kHz use the 3010S as the switch element — cheap, stocked everywhere, and the 4.5V row works with the 5V control rails those boards carry.

Why Buy NCE3010S from ICMASS?

Every lot tested at both drive points. We batch-test R_DS(on) at 10V and 4.5V against the datasheet maxes before shipping. A remarked part from a smaller die fails the 4.5V/5A check by 1.5-2× — the fastest way to catch counterfeits in this class.

Cross-reference support for the whole 30V family. Not sure whether your board wants the 3010S, the 3015S, or the 3018AS? Send us load current, gate drive voltage, and board copper — we'll tell you which die your design actually needs.

Legacy-socket migration help. Replacing an AO4496 or FDS6690 socket? Tell us the old part number and we'll confirm the R_DS(on) row matches at your drive voltage before you commit a BOM.

Frequently Asked Questions About NCE3010S

Q1: Can it really carry 10A continuous?

A: Only with the PCB copper to move the heat. The datasheet derates to 7A at 100°C, and the package is rated 2.5W with a 50°C/W thermal number measured for 10 seconds. At 10A and 12mΩ the conduction loss alone is 1.2W. With ≥100mm² drain copper and thermal vias, the honest continuous envelope is 5-7A depending on ambient.

Q2: Is it a logic-level MOSFET? Can a 3.3V GPIO drive it?

A: It's a 4.5V-specified part — a 5V-logic MOSFET, not a 3.3V one. R_DS(on) is guaranteed at 4.5V and 10V only, and V_GS(th) runs to 3V max. Engineering guidance from the Arduino forums and TME is consistent: don't run a 4.5V-specified part from a 3.3V rail and expect the rated R_DS(on). For 3.3V systems, pick a part specified at 2.5V or lower, or add a gate driver.

Q3: Can I drop it into an AO4496 or FDS6690 socket?

A: Yes — same SO-8 pinout and same 30V/10A class, with one check. Pins 1-3 Source, pin 4 Gate, pins 5-8 Drain match. Verify the R_DS(on) guarantee at your actual gate drive: the 3010S specifies 12mΩ max at 10V and 16mΩ max at 4.5V, which covers what those legacy sockets promised.

Q4: Why is the 4.5V R_DS(on) tested at 5A instead of 10A?

A: Because before full saturation, on-resistance rises with current. The datasheet's 4.5V row is measured at I_D = 5A, and the R_DS vs drain-current curve shows why: below the full 10V gate drive the die isn't fully enhanced, so R_DS at 10A/4.5V will read higher than the 16mΩ max. Design at 4.5V for loads near 5A, or drive at 10V for the full 10A.

Q5: How hot will it run at 5A or 8A?

A: Work the numbers from the datasheet max. 5A at 12mΩ is 0.3W — a 15°C rise at the 50°C/W number. 8A is 0.77W, a 38°C rise. But the 50°C/W is a 10-second rating: steady-state SO-8 thermal resistance on a typical board lands higher (Fairchild's AN-1032 puts minimal-copper SO-8 near 125°C/W). Big drain copper and vias are what make 8A survivable.

Q6: Can I use two in parallel for more current?

A: Yes, with equal gate traces and shared drain copper. Keep the two parts on the same copper pour so current shares by temperature, and keep gate traces equal length so they switch together. Parallel pairs are the standard way to push an SO-8-class design past one part's envelope without changing package.

Q7: What switching frequency is realistic?

A: Into the hundreds of kHz with a real driver. td(off) is 100ns and Q_g is 32.5nC — numbers a TC4420-class driver handles easily. Driven straight from a 5V MCU GPIO (a few mA of pull capability), stay in the tens of kHz. The gate charge and input capacitance decide, not the current rating.

Q8: Is 30V enough for a 24V system?

A: Only for clean, tightly-regulated 24V rails. A 24V lead-acid battery floats at 27.6-28.8V — under 1.2V of headroom for switching spikes at 30V. For raw battery rails or inductive loads, step to the 40V/60V SOP-8 class. For 12V systems (14.4V float) 30V is comfortable with margin.

Q9: How do I verify a genuine NCE3010S?

A: Measure R_DS(on) at both drive points. A genuine part reads within the 12mΩ (10V/10A) and 16mΩ (4.5V/5A) maxes. Remarked parts from smaller dies typically fail the 4.5V check by 1.5-2×. Check the marking reads NCE3010 and confirm a true 150-mil SO-8 body — not a smaller die glued into the frame.

Q10: Which applications actually buy this part?

A: Cordless tool boards, appliance load switches, small inverters, and UPS sections. From what we see in Shenzhen (2025–2026), the 30V/10A SO-8 class is a volume socket — the parts go into compact SMD power stages where the old AO4496/FDS6690-era designs used to sit, at roughly a quarter of the import price.
