Thyristors Standard Unidirectional SIDACs RoHS Kxxx0yU SIDAC Series Description The SIDAC is a silicon unilateral 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 component. SIDACs feature glass-passivated junctions to ensure a rugged and dependable component capable of withstanding harsh environments.
