BUK9Y6R5-40HX

Overview

The Nexperia BUK9Y6R5-40HX is an automotive qualified N-channel MOSFET utilizing Trench 9 low ohmic superjunction technology. It features a 40 V drain-source voltage rating and a maximum continuous drain current of 70 A at 25 °C mounting base temperature. The device exhibits a typical on-state resistance (RDSon) of 5.6 mΩ at VGS = 10 V and ID = 20 A, with a maximum of 6.5 mΩ. Total gate charge is typically 21 nC. Thermal resistance from junction to mounting base is 2.35 K/W maximum. Operating junction temperature ranges from -55 °C to +175 °C.

Feature Summary

Fully automotive qualified to AEC-Q101 standards for high reliability in thermally demanding environments.
Trench 9 Superjunction technology provides enhanced power density, improved safe operating area, and lower RDSon compared to standard TrenchMOS.
LFPAK Gull Wing leads absorb mechanical stress during thermal cycling, ensuring high board level reliability.
Visual AOI soldering inspection capability eliminates the need for expensive X-ray equipment.

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 the manufacturer's official documentation to confirm package variant and reel specifications. Confirm that the component meets the required AEC-Q101 qualification status for your specific application environment. Ensure compatibility with LFPAK56 (SOT669) footprint dimensions during PCB layout design. Cross-reference marking codes to validate authenticity upon receipt.

Selection Notes

Select this component when automotive qualification and high thermal endurance are required. The logic level gate drive allows efficient control with standard gate voltages. Consider the LFPAK56 package for its superior mechanical robustness and visual inspection benefits over traditional QFN packages. Evaluate thermal management requirements based on the specified junction-to-mounting base thermal resistance.
