IRHY55130CM R5 N-channel MOSFET is a rad hard device with 100V and 18A capacity. Housed in a TO-257AA package, the electrical performance of this COTS device is up to 500krad(Si) TID. Low RDS(on) and gate charge reduce power losses resulting in high performance and reliability in space applications. Switching applications, such as DC-DC converters and motor control, benefit from low losses.
