Notes:
1) Blocking capability may be lost during
and immediately following surge
current interval.
2) Overload may not be repeated until
junction temperature has returned
to steady-state rated value.

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
• AC Circuit Oriented
• Triggering Voltage of 79V to 330V
• RoHS Compliant

Applications
Suitable for high voltage power supplies, natural gas igniters, high-pressure Sodium lamps, and Xenon flash ignition.
