International Rectifier in El Segundo, Calif., is offering four radiation-hardened solid-state relays for high-reliability (hi-rel) applications. The new hermetically sealed relays are all-electronic devices designed to replace electro-mechanical relays in power bus switching, heater-control circuits, battery charging, and other hi-rel applications. The first relay is the RDHA710SE10A2Q (SMD mount) dual relay, with current handling capabilities of 20 amps, which is enough to allow normally applied de-rating. The second and third devices are the RDHA701FP10A8Q and the RDHA701FP10A8C, containing eight SPST, NO, 1.5 amp, 100-volt relays with selectable input actuation methods and a choice of rise/fall time control. They are housed in a 64-pin surface mount package. The fourth relay is the RDHA720SF06A1N, a single 20 amp, 60-volt device, also in an SMD package.
