The IRHF57214SESCS R5 N-channel MOSFET is a reliable space-grade MOSFET. It is rad hard, has a 250V and 2.2A rating, and is QIRL qualified. Its low RDS(on) and gate charge minimize power losses, making it ideal for DC-DC converters and motor control applications. With proven performance in satellite applications, it retains the benefits of MOSFETs, including voltage control, fast switching, and temperature stability.
