BUK7Y3R5-40HX Description

Short technical summary and product information.

The BUK7Y3R5-40HX is an automotive-qualified N-channel MOSFET from Nexperia, utilizing Trench 9 superjunction technology for low on-resistance and high efficiency. It features a drain-source voltage rating of 40V and a continuous drain current of 120A at 25°C case temperature. The device offers a maximum drain-source on-resistance of 3.5 mΩ at 10V gate drive, with typical values around 2.9 mΩ. Gate charge is 53 nC, and input capacitance is 3441 pF, enabling fast switching.

 

Designed for demanding automotive environments, the MOSFET is AEC-Q101 qualified and operates over a junction temperature range of -55°C to 175°C. It comes in a robust LFPAK56 (SOT-669) surface-mount package with Gull Wing leads, which provide excellent board-level reliability during thermal cycling and allow for visual solder joint inspection.

 

Typical applications include 12V automotive systems such as motor, lamp, and solenoid control, start-stop micro-hybrid systems, transmission control, and ultra high-performance power switching. The tight gate threshold voltage spread facilitates easy paralleling of multiple devices.
