Product details

Overview

STN2NE10L from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in SOT-223 package, rated for 100 V drain-source voltage, 0.33 Ω R_DS(on) at V_GS = 10 V and I_D = 1 A, 1.8 A continuous drain current at T_C = 25°C, and featuring 100% avalanche tested ruggedness for reliable switching in power-constrained DC-DC converters and motor control stages.

For engineers reviewing the STN2NE10L datasheet, STN2NE10L pinout, STN2NE10L application, or STN2NE10L equivalent, key selection criteria include its low-threshold gate drive compatibility (V_GS(th) = 1–3 V), high dv/dt immunity (6 V/ns), and SOT-223 thermal performance (R_thj-pcb = 50 °C/W) in space-limited industrial power modules.

Technical Context

This MOSFET employs ST's "Single Feature Size™" strip-based STripFET™ process to achieve high cell density and low on-resistance while maintaining robust unclamped inductive switching capability. Its avalanche ruggedness is validated by 20 mJ single-pulse energy rating (E_AS) and 1.8 A repetitive avalanche current (I_AR).

The device operates with gate threshold voltage of 1–3 V and supports logic-level drive (V_GS = 5 V yields R_DS(on) ≤ 0.45 Ω). Its dynamic parameters-C_iss = 345 pF, Q_g = 10–14 nC, and t_d(off)/t_f = 22/8 ns-enable fast, efficient switching in 50–100 kHz SMPS topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Supports input rails up to 80 V DC with margin for transients in offline auxiliary supplies.
R_DS(on)	0.33 Ω @ V_GS = 10 V, I_D = 1 A - Enables <1 W conduction loss at 1.8 A, suitable for thermally constrained PCB layouts.
I_D (cont.)	1.8 A @ T_C = 25°C - Defines maximum steady-state current under heatsinked conditions.
E_AS	20 mJ @ T_j = 25°C - Guarantees safe operation during unclamped inductive turn-off events in relay drivers or solenoid controls.
dv/dt	6 V/ns - Resists false triggering in noisy industrial environments with fast-rising bus voltages.
Q_g	10–14 nC - Determines gate driver strength requirement; compatible with low-power microcontroller GPIOs via buffer.
R_thj-pcb	50 °C/W - Specifies junction-to-PCB thermal resistance with standard copper pour, enabling thermal design without external heatsink.

Pinout & Package

SOT-223 package with exposed drain tab (Pin 2) for enhanced thermal conduction and mechanical anchoring. Standard 4-pin configuration with source (Pin 1), gate (Pin 3), and drain (Pin 2 & Pin 4 electrically common).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Source	Reference node for gate drive; connects to low-side return path and provides ground reference for internal body diode.
Pin 2	Drain (tab)	Main power output terminal; electrically tied to Pin 4; soldered to large copper area for thermal dissipation.
Pin 3	Gate	Control input; requires <3 V threshold to turn on; sensitive to ESD-requires series resistor and layout care.
Pin 4	Drain	Secondary drain connection; redundant with Pin 2 for routing flexibility and current sharing in high-current traces.

Key Features

Feature	Design Value
Avalanche ruggedness	100% factory-tested; enables reliable operation in inductive load switching without external snubbers.
Low R_DS(on)	0.33 Ω at 10 V drive - reduces conduction losses in battery-powered 12–24 V systems.
Logic-level gate	V_GS(th) = 1–3 V - allows direct drive from 3.3 V or 5 V MCUs without level-shifting circuitry.
High dv/dt immunity	6 V/ns - prevents spurious turn-on in high-noise motor drive or industrial PLC outputs.
ECOPACK® compliance	Lead-free second-level interconnect - meets RoHS and JEDEC JESD97 environmental requirements.

Applications

DC-DC Converter Secondary Side

Industrial Relay Driver

Use Scenario: Low-voltage synchronous rectification in isolated flyback or forward converters delivering 5–12 V at ≤2 A.

IC Role / Device Role / Timing Role: N-channel power switch replacing Schottky diode to reduce forward drop and improve efficiency.

Use Value: 0.33 Ω R_DS(on) cuts conduction loss by >40% vs. 0.5 V Schottky, raising efficiency from ~82% to ~87% at full load.

Use Scenario: Solid-state replacement for electromechanical relays controlling 24 V DC solenoids or indicator lamps in PLC I/O modules.

IC Role / Device Role / Timing Role: Low-side switch with integrated body diode for inductive kickback clamping.

Use Value: 20 mJ E_AS rating eliminates need for external flyback diode, simplifying BOM and board layout.

LED Constant-Current Driver

Automotive Accessory Control

Use Scenario: PWM dimming stage for high-brightness LED strings in signage or emergency lighting.

IC Role / Device Role / Timing Role: High-speed switching element modulating current through LED load at 1–10 kHz.

Use Value: 22 ns t_d(off) and 8 ns t_f ensure clean PWM edges with minimal dead-time distortion and reduced thermal stress.

Use Scenario: Load control for interior lighting, mirror heaters, or window lift motors in 12 V automotive subsystems.

IC Role / Device Role / Timing Role: Protected low-side switch interfacing MCU GPIO to vehicle battery rail.

Use Value: 100 V V_DS withstands load-dump transients up to 87 V per ISO 7637-2, eliminating need for TVS clamping.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2NK10Z	TO-92 package, higher R_DS(on) (0.55 Ω), lower I_D (1.2 A), Zener-protected gate	Limited to <1 W dissipation; unsuitable for PCB-constrained SOT-223 footprints	Select only when gate protection is prioritized over thermal performance and footprint compatibility.
IRLB8721PBF	SO-8 package, lower R_DS(on) (0.015 Ω), higher I_D (34 A), logic-level but not avalanche-rated	Requires external avalanche protection in inductive loads; incompatible pinout and thermal interface	Choose for high-current, low-loss applications where board space and avalanche testing are secondary concerns.

Compared with STP2NK10Z and IRLB8721PBF, STN2NE10L uniquely balances SOT-223 footprint, 100% avalanche validation, and 0.33 Ω R_DS(on), making it optimal for compact, reliability-critical 1–2 A industrial switching nodes where thermal and transient robustness are non-negotiable.

FAQ

Is STN2NE10L still in active production?

No-STMicroelectronics has marked STN2NE10L as obsolete per its official datasheet revision history (Rev 5, Feb 2007). However, Aetrix Electronics maintains verified legacy stock with full traceability, including original ST packaging and date codes, supporting ongoing maintenance and legacy system builds.

Can STN2NE10L be driven directly by a 3.3 V microcontroller GPIO?

Yes-its gate threshold voltage range (1–3 V) ensures turn-on at 3.3 V, and R_DS(on) remains ≤0.45 Ω at V_GS = 5 V. For robust switching, use a 10–100 Ω series gate resistor to limit peak current and suppress ringing without compromising rise/fall times.

What is the maximum safe operating temperature for continuous operation?

The absolute maximum junction temperature is 150°C, but continuous operation above 125°C degrades long-term reliability. With R_thj-pcb = 50 °C/W and P_TOT = 2.5 W at T_C = 25°C, sustained operation at 1.8 A requires PCB copper area ≥ 250 mm² to keep T_j ≤ 125°C under ambient 70°C conditions.

Does STN2NE10L include integrated ESD protection on the gate?

No-the datasheet does not specify gate Zener or oxide protection. The device relies on external handling precautions and PCB-level ESD safeguards (e.g., series resistor + TVS clamp to source). Gate leakage (±100 nA at ±20 V) confirms absence of integrated protection diodes.
