This part is active, but not recommended for new design. A new footprint compatible package version will be released soon. Rad hard R9 N-channel MOSFET IRHNMC9A3120 is a 100V and 23A device packaged in a ceramic SMD-0.2. Capable of withstanding up to 300krad(Si) TID, these COTS MOSFETs feature improved immunity to Single Event Effects (SEE) and are ideal for space applications. Their low RDS(on) and fast switching times make them perfect for DC-DC converters and motor drives.
