Product details
Overview
BUK7275-100A from Nexperia is a standard-level N-channel TrenchMOS FET in DPAK (SOT428) package, rated for 100 V VDS, 21.7 A continuous drain current at Tmb = 25 °C, and 175 °C junction temperature. It delivers 64 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and is AEC-Q101 qualified for automotive power switching in 12 V/24 V/42 V systems.
For engineers reviewing the BUK7275-100A datasheet, BUK7275-100A pinout, BUK7275-100A application, or BUK7275-100A equivalent, this device is selected for thermally demanding load switching where low conduction loss, avalanche ruggedness (100 mJ), and gate-drive compatibility with standard 10 V logic are critical design requirements.
Technical Context
This MOSFET uses TrenchMOS technology to achieve low RDS(on) while maintaining robust thermal performance up to 175 °C junction temperature. Its gate threshold voltage ranges from 1 V (Tj = 175 °C) to 4.4 V (Tj = −55 °C), enabling stable turn-on across automotive ambient extremes.
The device features integrated source-drain diode with 0.85 V forward voltage at 25 A and 64 ns reverse recovery time, supporting inductive load commutation. Its 1.7 K/W Rth(j-mb) thermal resistance and 89 W Ptot at Tmb = 25 °C enable high-power density mounting on heatsinked PCBs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP16NF10 | 100 V, 16 A, RDS(on) = 75 mΩ @ 10 V, TO-220 package, no AEC-Q101 qualification | Non-automotive industrial use only; lacks automotive qualification and thermal performance at elevated temperature | Select when cost-sensitive non-automotive designs require through-hole mounting and lower current (<16 A) suffices |
| IRFZ44NPBF | 55 V, 49 A, RDS(on) = 28 mΩ @ 10 V, TO-220, no AEC-Q101, lower voltage rating | Restricted to ≤55 V systems; unsuitable for 42 V automotive or 100 V transient protection | Choose only for 12 V/24 V non-automotive applications requiring higher current and lower RDS(on), with no thermal or qualification constraints |
Compared with STP16NF10 and IRFZ44NPBF, the BUK7275-100A uniquely combines AEC-Q101 qualification, 100 V rating, and 175 °C operation-making it the sole option among the three for thermally aggressive automotive 12–42 V load switching where reliability and transient robustness are mandatory.

FAQ
Is BUK7275-100A suitable for high-frequency PWM motor control?
Yes-it supports PWM switching with 8 ns td(on), 39 ns tr, 26 ns td(off), and 24 ns tf, enabling efficient operation up to ~100 kHz. Its 910 pF Ciss and 80 pF Crss minimize Miller-induced shoot-through risk, but gate drive strength must exceed 1 A peak to fully exploit these timings in high-dV/dt environments.
What is the maximum allowable PCB copper area for thermal performance?
The datasheet specifies "minimum footprint" for Rth(j-a) = 71.4 K/W; optimal thermal performance requires ≥200 mm² of 2 oz copper connected to the mounting base. For 89 W Ptot, a 500 mm² thermal pad with 4+ thermal vias to inner ground planes reduces Tj rise by ~15 K versus minimum layout.
Does BUK7275-100A require a gate resistor for stability?
A series gate resistor (5.6 Ω typical, per datasheet test condition) is recommended to dampen ringing caused by LD = 2.5 nH and LS = 7.5 nH internal inductances. Omitting it risks oscillation during fast transitions, especially with long gate traces or high-current layouts.
Can BUK7275-100A replace BUZ72 in existing designs?
No-BUZ72 is a 500 V, 12 A TO-220 device with different voltage class, current rating, package, and thermal profile. BUK7275-100A targets lower-voltage, higher-current, surface-mount automotive applications; direct substitution would violate voltage margin and thermal interface requirements.
