Schematic Symbol
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.
Features
• A C Circuit Oriented • T riggering Voltage of 79V
to 330V
• R oHS Compliant
