The SIDAC is a silicon bilateral voltage triggered switch. Upon application of a voltage exceeding the SIDAC breakover voltage point, the SIDAC switches on through a negative resistance region to a low on-state voltage. Conduction continues until the current is interrupted or drops below the minimum holding current of the device.SIDACs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments.Feature
sAC Circuit Oriented Triggering Voltage of 79V to 330V RoHS CompliantApplication
sSuitable for high voltage power supplies, natural gas igniters, high-pressure Sodium lamps, and Xenon flash ignition.
