Clairex takes great pride in an organization that has nearly 170 years of technical experience in optoelectronics and related fields of the electronics market. We emphasize an ethical responsibility to all our customer base with a goal of being the best supplier of optoelectronic components, with production exclusively in the USA. Clairex Technologies (dba Clairex Semiconductor) was started in 1993 when David Catter, Sr. and a business partner proposed to improve and supply a part needed by the General Aviation Avionics division of a Fortune 500 company. That part had been supplied previously by another company, but the lifetime purchase yielded less than 10% after accounting for mechanical and electrical failures. The customer determined that a redesign of the Avionics module would be prohibitively expensive, but a key part, a photoconductor-based high-voltage isolator was not currently available anywhere. The previous supplier had no interest in supplying that part, but word got out to the principals of Clairex; a better design was proposed, accepted, tooled, and production began with photoconductors manufactured in Plano, Texas.
