BUK9M15-40HX

Overview

The BUK9M15-40HX is an automotive qualified logic level N-channel MOSFET utilizing Trench 9 superjunction technology. It features a drain-source voltage of 40 V and a continuous drain current of 30 A at 25 °C mounting base temperature. The device exhibits a maximum on-state resistance of 15 mΩ at VGS = 10 V and ID = 10 A. Total power dissipation reaches 44 W under specified conditions. The component operates within a junction temperature range of -55 °C to +175 °C and includes repetitive avalanche rating capabilities.

Feature Summary

Fully automotive qualified to AEC-Q101 standard for high performance applications
Trench 9 superjunction technology provides low power losses and high power density
LFPAK copper clip package ensures high robustness, reliability, and thermal efficiency
Repetitive avalanche rated for enhanced ruggedness in demanding environments

Applications

12 V automotive systems
Powertrain, chassis, body and infotainment applications
Medium/Low power motor drive
DC-DC systems
LED lighting

Procurement Notes

Verify the specific suffix 'HX' against the official Nexperia ordering information table to confirm packaging details such as reel specifications or tape-and-reel dimensions. Ensure the procurement documentation references the correct SOT1210 package version. Cross-reference the marking code '91540H' with incoming inspection requirements to validate authenticity and traceability during quality control processes.

Selection Notes

Select this component for designs requiring automotive qualification and logic level gate drive compatibility. The LFPAK33 package supports surface mount assembly with gull wing leads suitable for automated optical inspection. Evaluate PCB thermal design constraints, as practical current limits are influenced by mounting base temperature and heat dissipation capabilities rather than absolute maximum ratings alone.

Part Context

This device belongs to the Nexperia BUK9M series of N-channel MOSFETs designed for automotive use. It employs Trench 9 technology to achieve superior performance metrics compared to previous generations. The LFPAK33 (SOT1210) package variant integrates a copper clip for improved thermal conductivity and electrical robustness, distinguishing it from standard plastic packages.
