International Rectifier RAD-Hard solid state relay

International Rectifier has introduced a RAD-Hard solid state relay for power bus switching, heater control circuits and battery charging used in high-reliability, space-qualified applications.

The RDHA701CD10A2N radiation-hardened DC single-pole, single throw-type SSR is designed to improve reliability by replacing traditional electromechanical relays that are vulnerable to vibration and shock. The relay features low on-state resistance to improve thermal efficiency and is offered in a low-profile, hermetically sealed eight-lead ceramic package.

The 100 V device is characterised for total dose levels up to 100 krad (Si). The RDHA701CD10A2N is a dual-channel device rated at 100 V and 1 A with 1000 V input to output and channel-to-channel isolation.
