BUK7Y4R4-40EX Description

Short technical summary and product information.

The BUK7Y4R4-40EX is an N-channel MOSFET from Nexperia, utilizing TrenchMOS technology for high efficiency. It is rated for a maximum drain-source voltage of 40V and a continuous drain current of 100A at 25°C case temperature. The device features a low on-resistance of 4.4mΩ (max) at VGS=10V and ID=25A, enabling high current handling with minimal conduction losses.

 

This MOSFET is AEC Q101 qualified and repetitive avalanche rated, making it suitable for demanding automotive environments. It operates over a junction temperature range of -55°C to 175°C, with a maximum power dissipation of 147W at 25°C. Key dynamic characteristics include a total gate charge of 39nC (max) and input capacitance of 2781pF (max) at VDS=25V.

 

Typical applications include 12V automotive systems, motor control, lamp and solenoid drivers, transmission control, and ultra high performance power switching. The device is offered in a surface-mount LFPAK56 (Power-SO8) package, corresponding to SC-100/SOT-669, with a standard level gate threshold voltage (VGS(th) max 4V) and recommended drive voltage of 10V.
