Product Description

The SIDAC is a silicon bilateral voltage triggered switch designed for AC circuit applications. It activates when the applied voltage exceeds the SIDAC breakover voltage point, transitioning through a negative resistance region to a low on-state voltage. Conduction is maintained until the current is interrupted or falls below the device's minimum holding current. Featuring glass-passivated junctions, SIDACs offer a rugged and dependable solution for harsh environments. They are suitable for high voltage power supplies, natural gas igniters, high-pressure sodium lamps, and Xenon flash ignition.
