BUK7Y1R0-40NX

Overview

The BUK7Y1R0-40N is an automotive qualified N-channel MOSFET utilizing Trench 15 e-TBO technology in an LFPAK56 package. It features a drain-source voltage of 40 V and a maximum on-state resistance of 0.97 mΩ at 25 °C. The device supports a continuous drain current of 320 A and a peak pulsed current of 1465 A. Total gate charge is typically 135 nC, with a junction-to-mounting base thermal resistance of 0.48 K/W. It operates within a junction temperature range of -55 °C to 175 °C.

Feature Summary

Fully automotive qualified to AEC-Q101 standards for high reliability
Trench 15 e-TBO technology merges Superjunction ruggedness with Split-Gate low RDSon performance
LFPAK Gull Wing leads provide high board level reliability and enable visual AOI soldering inspection
LFPAK copper clip technology reduces thermal resistance and package inductance while increasing current capability

Applications

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

Procurement Notes

Verify the specific part number BUK7Y1R0-40N against the official Nexperia datasheet to confirm technical specifications and packaging details. Ensure that the ordering suffix matches the required variant, as suffixes may indicate differences in tape and reel configuration or marking codes. Confirm compliance with AEC-Q101 requirements if automotive qualification is mandatory for the intended application environment.

Selection Notes

Select this component for applications requiring low conduction losses and high ruggedness in compact automotive designs. The LFPAK56 package offers superior thermal performance and mechanical stability compared to traditional QFN packages due to its gull wing leads and copper clip technology. Consider the tight VGS(th) limits when paralleling multiple units to ensure balanced current sharing and optimal system efficiency.

Part Context

This device belongs to Nexperia's portfolio of automotive-grade power MOSFETs designed for demanding environments. It employs advanced Trench 15 e-TBO technology to achieve a balance between low on-resistance and high avalanche ruggedness. The LFPAK56 (SOT669) package is specifically engineered to handle high currents and thermal cycling stress, making it suitable for modern vehicle electrical architectures.
