This part is active, but not recommended for new design. A new footprint compatible package is currently available (see featured products). IRHNMC597110 is a R5, rad hard, -100V, -3.1A, single, P-channel MOSFET in a SMD-0.2 package, ceramic lid. It has electrical performance up to 100krad(Si) TID and has low RDS(on) and low gate charge, making it suitable for switching applications such as DC-DC converters and motor controllers, while retaining the advantages of MOSFETs.
