Product details

Overview

STD26NF10 from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in DPAK package, rated for 100 V drain-source voltage, 25 A continuous drain current at 25°C, and 0.033 Ω typical R_DS(on) at V_GS = 10 V. It features low gate charge (55 nC), exceptional dv/dt capability (13 V/ns), and 100% avalanche tested robustness-designed for high-efficiency switching in automotive power distribution systems.

For engineers reviewing the STD26NF10 datasheet, STD26NF10 pinout, STD26NF10 application, or STD26NF10 equivalent, key selection criteria include its 1.5 °C/W junction-to-case thermal resistance, 20 S forward transconductance at 12.5 A, and suitability for unclamped inductive load switching with 480 mJ single-pulse avalanche energy rating.

Technical Context

This MOSFET employs ST's STripFET™ II process to minimize input capacitance (C_iss = 1550 pF) and gate charge, enabling fast switching with reduced drive loss. Its rugged body diode supports reverse recovery times as low as 88 ns under 25 A/100 A/µs conditions.

The device is characterized for automotive-grade reliability: 100% avalanche tested, rated for T_j up to 175°C, and qualified per JEDEC JESD97 with ECOPACK® lead-free packaging. Safe operating area (SOA) is defined up to 100 A pulsed drain current with pulse-width-limited derating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage before avalanche onset; enables use in 48 V automotive bus and industrial 100 V DC systems.
R_DS(on)	0.033 Ω (typ) at V_GS = 10 V - Low conduction loss yielding ≤ 10.3 W I²R dissipation at 18 A, critical for thermally constrained PCB layouts.
Q_g	55 nC - Total gate charge determines driver strength requirement; enables efficient operation with low-power gate drivers (e.g., TC4427).
E_AS	480 mJ - Single-pulse avalanche energy at T_j = 25°C - Supports reliable operation during inductive turn-off transients without external snubbers.
dv/dt	13 V/ns - Peak diode recovery dv/dt rating - Ensures immunity to false triggering during fast commutation in motor control and SMPS.
R_thj-case	1.5 °C/W - Junction-to-case thermal resistance - Enables direct heatsink mounting for >80 W continuous power dissipation with minimal thermal interface resistance.

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection; 3-terminal configuration optimized for high-current PCB routing and thermal management.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Source terminal (low-side reference)	Connected to ground or low-side return path; carries full load current and defines common reference for gate drive.
2 (Gate)	Control electrode	High-impedance input requiring <200 nA leakage; driven by logic-level or dedicated gate driver to switch channel on/off.
3 (Drain)	Main power output / high-side connection	Exposed metal pad (Pin 3) serves as primary drain connection and thermal path to heatsink or copper pour.

Key Features

Feature	Design Value
STripFET™ II process technology	Reduces C_iss and Q_g vs. standard planar MOSFETs-enabling higher switching frequency without excessive gate drive loss.
100% avalanche tested	Guarantees minimum E_AS = 480 mJ-eliminates need for design margining against unclamped inductive energy in relay/motor drivers.
Low R_DS(on) × Q_g figure-of-merit	0.033 Ω × 55 nC = 1.815 Ω·nC-balances conduction and switching losses for optimal efficiency in 20–100 kHz PWM applications.
ECOPACK® lead-free packaging	Complies with RoHS and JEDEC JESD97; marked on inner box label-ensures environmental compliance without solderability trade-offs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 100 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF540N	R_DS(on) = 0.044 Ω (typ), Q_g = 71 nC, no avalanche rating specified	Lacks guaranteed avalanche energy; SOA not characterized for pulsed inductive loads	Acceptable for non-critical linear or resistive switching where cost is prioritized over ruggedness.
STP26NF10	Same die, TO-220 package; identical R_DS(on), Q_g, and E_AS; R_thj-case = 1.25 °C/W	Through-hole mounting; better natural convection cooling but larger board footprint	Select when mechanical robustness, manual assembly, or legacy TO-220 heatsink compatibility is required.

Compared with IRF540N, STD26NF10 delivers superior avalanche immunity and lower switching loss; versus STP26NF10, it trades slightly higher thermal resistance for compact surface-mount integration and automated assembly compatibility.

FAQ

Is STD26NF10 suitable for 48 V battery-powered motor control?

Yes. With 100 V V_DS, 25 A continuous current, and 480 mJ avalanche energy, STD26NF10 safely handles 48 V bus voltages plus transient spikes up to 100 V. Its 0.033 Ω R_DS(on) limits conduction loss to 20 W at 25 A, making it appropriate for brushed DC motor H-bridges in robotics and mobility applications.

What is the maximum gate-source voltage rating?

The absolute maximum V_GS is ±20 V. Operation above ±15 V risks oxide damage; typical gate drive uses +10 V for full enhancement and 0 V or –5 V for guaranteed turn-off. Gate threshold voltage is 2–4 V, so logic-level 3.3 V or 5 V microcontrollers require a gate driver for reliable switching.

Does STD26NF10 have a built-in body diode?

Yes. It integrates a fast-recovery source-drain diode with 1.5 V forward voltage at 25 A and 88 ns reverse recovery time at 150°C. This diode supports freewheeling current in inductive loads and enables synchronous rectification in buck converters when used in low-side configuration.

Can STD26NF10 be mounted directly to a heatsink?

Yes. The DPAK package exposes the drain (Pin 3) as a large metal pad designed for direct thermal interface to a heatsink or copper pour. With R_thj-case = 1.5 °C/W, a 10°C/W heatsink yields ~16.5°C/W total thermal resistance-supporting ~60 W continuous dissipation at ΔT = 100°C, assuming proper thermal paste and mounting pressure.
