BUK9J0R9-40HX

Overview

The Nexperia BUK9J0R9-40HX is an automotive qualified N-channel MOSFET utilizing Trench 9 low ohmic superjunction technology within an enhanced LFPAK56E package. It features a drain-source voltage of 40 V and a typical on-state resistance of 0.82 mΩ at 25 °C. The device supports a continuous drain current of 220 A and total power dissipation of 500 W. Gate-source voltage limits are -10 V to 16 V, 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 in thermally demanding environments up to 175 °C.
Trench 9 Superjunction technology provides reduced cell pitch for enhanced power density, lower RDSon, improved SOA, and avalanche capability.
LFPAK Gull Wing leads offer high board level reliability by absorbing mechanical stress during thermal cycling compared to traditional QFN packages.
LFPAK copper clip technology improves reliability by reducing thermal resistance and on-state resistance while increasing maximum current capability.

Applications

12 V automotive systems
Motors, lamps and solenoid control
Start-Stop micro-hybrid applications
Transmission control
Ultra high performance power switching

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape configuration. Ensure the component matches the exact part number BUK9J0R9-40H for electrical specifications. Confirm RoHS compliance and REACH SVHC status through the manufacturer's latest product data sheet before integration into production designs.

Selection Notes

Select this component for applications requiring high current handling and low conduction losses in automotive environments. The logic level gate drive compatibility allows for efficient control with standard 4.5 V or 10 V drivers. Consider the LFPAK56E package for its superior thermal management and mechanical robustness in space-constrained PCB layouts.

Part Context

This device belongs to Nexperia's automotive-grade MOSFET portfolio designed for high-efficiency power switching. It leverages advanced superjunction technology to achieve industry-leading figures of merit within the LFPAK family. The part is engineered to meet stringent automotive reliability standards while providing compact form factors for modern vehicle electronics.

Replacement Considerations

Direct substitutes include other Nexperia parts in the BUK9J series with similar voltage and resistance ratings, such as BUK9J1R4-40H. Verify pinout compatibility and thermal characteristics when replacing components to ensure system performance remains within specified limits.
