BUK7Y3R0-40HX

Overview

The Nexperia BUK7Y3R0-40HX is an automotive qualified N-channel MOSFET utilizing Trench 9 superjunction technology in a LFPAK56 (SOT669) package. It features a drain-source voltage of 40 V and a continuous drain current of 120 A at 25 °C mounting base temperature. The typical on-state resistance is 3 mΩ at VGS = 10 V and ID = 25 A. Total power dissipation reaches 172 W under specified conditions, with a junction temperature range from -55 °C to +175 °C.

Feature Summary

Fully automotive qualified to AEC-Q101 standards for high performance and endurance.
Trench 9 Superjunction technology provides enhanced power density and improved safe operating area compared to standard TrenchMOS.
LFPAK Gull Wing leads absorb mechanical stress during thermal cycling, ensuring high board level reliability.
LFPAK copper clip technology reduces thermal resistance and increases maximum current capability.

Applications

12 V automotive systems
Motors, lamps and solenoid control
Start-Stop micro-hybrid applications
Transmission control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and reel specifications. Confirm that the component meets the required AEC-Q101 qualification status for your intended automotive application. Ensure compatibility with the LFPAK56 footprint dimensions provided in the datasheet before finalizing procurement orders.

Selection Notes

Select this component for designs requiring low on-state resistance within a compact surface-mount footprint. The tight gate-source threshold voltage limits facilitate easy paralleling of multiple devices for higher current handling. Consider the 175 °C junction temperature rating for operation in thermally demanding environments where standard components may fail.

Part Context

This device belongs to the Nexperia BUK7Y series of automotive-grade N-channel MOSFETs. It utilizes advanced Trench 9 superjunction technology to achieve lower RDSon values within the same physical footprint as previous generations. The LFPAK56 package offers superior thermal performance and mechanical robustness compared to traditional QFN packages.
