Kxxxzy SIDAC
Description
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.
