General Description
E9
The sidac is a silicon bilateral voltage triggered switch with
greater power-handling capabilities than standard diacs. 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.
Teccor’s sidacs feature glass-passivated junctions to ensure a
rugged and dependable device capable of withstanding harsh
environments.
Variations of devices covered in this data sheet are available for
custom design applications. Consult the factory for more informa-
tion.
