Product details
Overview
BUK9660-100A,118 from Nexperia is an AEC-Q101-qualified logic-level N-channel TrenchMOS FET in D2PAK (SOT404) package, designed for automotive power switching. It delivers 100 V drain-source voltage rating, 26 A continuous drain current at 5 V gate drive and 175 °C junction temperature capability, enabling robust operation in 12 V/24 V/42 V vehicle subsystems such as engine control modules and body electronics.
For engineers reviewing the BUK9660-100A,118 datasheet, BUK9660-100A,118 pinout, BUK9660-100A,118 application, or BUK9660-100A,118 equivalent, key selection criteria include RDS(on) at 4.5 V/5 V gate drive, avalanche energy rating (30 mJ), thermal resistance to mounting base (1.4 K/W), and compliance with automotive-grade reliability standards.
Technical Context
This device uses TrenchMOS technology to achieve low on-state resistance while maintaining high avalanche ruggedness and thermal stability. Its gate threshold voltage (1–2 V at 25 °C) ensures reliable turn-on with standard logic-level drivers, and its 175 °C maximum junction temperature supports placement near heat-generating components in under-hood environments.
The integrated source-drain diode exhibits 0.85–1.2 V forward voltage at 25 A and 61 ns reverse recovery time, supporting freewheeling in inductive load switching. Dynamic parameters-including 1440–1924 pF input capacitance and 124 ns rise time-enable efficient high-frequency PWM control up to several hundred kHz in motor and lamp drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Withstands transients up to 100 V in 12 V/24 V automotive systems without breakdown. |
| RDS(on) @ 5 V | 51–60 mΩ - Enables low conduction loss at logic-level gate drive, reducing thermal stress in continuous 26 A loads. |
| ID (cont) | 26 A @ Tmb = 25 °C - Supports high-current solenoid, motor, and lighting loads with minimal heatsinking. |
| EAS | 30 mJ - Absorbs unclamped inductive energy during switching faults, enhancing system robustness without external snubbers. |
| Rth(j-mb) | 1.4 K/W - Allows direct thermal coupling to PCB copper or heatsink, critical for sustained power dissipation up to 106 W. |
| VGS(th) | 1–2 V @ 25 °C - Ensures full enhancement with 3.3 V or 5 V microcontroller outputs without level-shifting circuitry. |
| QG | ~35 nC - Matches typical gate drivers for <1 µs switching transitions at 10 Ω external gate resistance. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N10F7 | 100 V, 220 A rated but 3.2 mΩ RDS(on) at 10 V; requires 10 V gate drive for full performance; TO-220FP package. | Higher current capacity suits industrial motor drives, not automotive space-constrained modules. | Select only if higher peak current (>50 A) and lower RDS(on) at 10 V are prioritized over AEC-Q101 compliance and logic-level drive. |
| IRF3205PBF | 55 V VDS, 110 A ID, 8 mΩ RDS(on) at 10 V; no AEC-Q101 qualification; TO-220 package. | Limited to 12 V systems; unsuitable for 24 V/42 V automotive transients or under-hood thermal profiles. | Acceptable for cost-sensitive non-automotive 12 V industrial switching where 175 °C operation and automotive qualification are unnecessary. |
Compared with STL220N10F7 and IRF3205PBF, BUK9660-100A,118 uniquely balances logic-level compatibility, AEC-Q101 qualification, 100 V rating, and D2PAK thermal performance-making it the only viable choice for space-constrained, thermally demanding automotive power nodes requiring zero design margin compromise.

FAQ
Is BUK9660-100A,118 qualified for automotive applications?
Yes. The BUK9660-100A,118 is fully AEC-Q101 qualified and designed for automotive critical applications, including engine control, body electronics, and ADAS subsystems. Its qualification covers temperature cycling, humidity testing, and mechanical shock per AEC standards, and it operates reliably from –55 °C to +175 °C junction temperature.
What is the maximum gate-source voltage for safe operation?
The absolute maximum gate-source voltage is ±10 V for continuous operation, with a pulsed peak limit of ±15 V (tp ≤ 50 µs). Exceeding ±10 V continuously risks gate oxide degradation; Nexperia recommends using gate resistors and clamping diodes when driving from higher-voltage sources or in noisy environments.
Can BUK9660-100A,118 be used in high-frequency PWM applications?
Yes. With 124 ns rise time, 67 ns fall time, and 35 nC total gate charge, the device supports PWM frequencies up to 200 kHz in well-designed gate-drive circuits. Layout must minimize source inductance (7.5 nH) and use low-inductance gate loops to avoid oscillation and overshoot.
Does the mounting base require electrical isolation from the PCB?
No-the mounting base is internally connected to the drain terminal and must be electrically tied to the drain net. When soldered to a large copper pour, it serves as both thermal path and part of the high-side power routing. Isolation is only required if the drain net is at a different potential than the PCB ground plane.
