Rad hard N-channel MOSFET JANSR2N7262 in a TO-205AF package is rated up to 200V and 5.5A. QPL-qualified, its electrical performance is up to 100krad(Si) TID. Low RDS(on) and gate charge minimize power losses in switching applications, while MOSFET benefits like voltage control and fast switching remain. This rad hard R4 MOSFET is flight-proven in satellite applications.
