International Rectifier Introduces Radiation-Hardened Solid State Relays that Replace Electro-Mechanical Relays in High Reliability Systems

International Rectifier introduces a new line of RAD-Hard solid state relays (SSRs) for high reliability (hi-rel) applications. The new SSRs are radiation-hardened, all-electronic devices, designed to improve reliability by replacing electro-mechanical relays in power bus switching, heater control circuits, battery charging and other hi-rel applications.

EL SEGUNDO, Calif. – International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced hermetically sealed, RAD-Hard solid state relays. Solid-state relays have switching times that are similar to electro-mechanical relay switching times, but are immune to vibration and shock, increasing reliability.

The new devices are characterized for total dose levels of up to 100k rad (Si) or higher, and single event effects (SEE) immunity up to an linear energy transfer (LET) of 37 MeV/(mg.cm2) or higher. Isolation is 1000V I/O. Class “P” (Unscreened), “H” and “K” screening is available.
