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.

Design Considerations
Careful selection of the correct component 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.
