Standard Bidirectional SIDACs
Kxxxzy Series
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.
Features

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

Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment will go a long
way toward extending the operating life of the Thyristor.
Overheating and surge currents are the main killers of
SIDACs. Correct mounting, soldering, and forming of the
leads also help protect against component damage.
