General Description

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 will continue until the cur-

rent is interrupted or drops below the minimum holding current of

the device.

Teccor offers the complete voltage range (95-330) over three dif-

ferent packages:

•

TO-92 (95-280 volts)

•

Axial lead DO-15X (95-280 volts)

•

Surface Mount DO-214AA (95-280 volts)

•

TO-202AB (190-330 volts)

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. Please consult the factory for more

information.
