Rad hard N-channel MOSFET JANSR2N7555U3 has a voltage rating of 250V and can handle 10A of current. With electrical performance up to 100krad(Si) TID and QPL classification, it comes in a R5 SMD-0.5 package. IR HiRel R5 technology provides decades of proven performance and reliability in satellite applications. Its low RDS(on) and low gate charge reduce power losses in switching applications.
