Crydom is the world's leading solid state switching manufacturer! Crydom was found in 1960 in Anaheim, California and acquired by International Rectifier Corporation in 1968.

Crydom invented the first solid state relay in 1971 and began manufacturing them in 1972. Their first panel mount SSR became the industry standard!

In 1987 Crydom was sold to Silicon Power Cube Corporation and then acquired by Schneider Electric in 2006. This was also when Schneider combined Crydom with their existing line of Crouzet solid state relays.

In 2015 Sensata Technologies Holding N.V. acquired the sensing divisions that included Kavlico, BEI, Crydom and Newall brands. In 2018 Sensata introduced new branding for all sub-brands to have the Sensata name included.
