BUK7K3R7-40NX

Overview

The BUK7K3R7-40NX is a dual N-channel standard level MOSFET rated for 40 V drain-source voltage and featuring a maximum on-resistance of 3.7 mOhm. It utilizes Trench 15 e-TBO technology to achieve high ruggedness and low power losses. The component is housed in an LFPAK56D package with gull-wing leads, designed for automotive applications requiring AEC-Q101 qualification at 175 °C.

Feature Summary

Dual MOSFET configuration integrating two silicon dies within a single LFPAK56D package to reduce board space.
Trench 15 e-TBO technology combining superjunction ruggedness with split-gate low on-resistance characteristics.
LFPAK copper clip technology providing improved thermal reliability and reduced package inductance.

Applications

12 V automotive systems
Motor, lighting, and solenoid control
Transmission control
Ultra high-performance power switching

Procurement Notes

Verify the specific suffix 'NX' against official Nexperia documentation to confirm exact tape-and-reel specifications or regional variant details. Ensure the selected component meets the required AEC-Q101 automotive qualification standards for your target application environment.

Selection Notes
