Standard Bidirectional DIAC Trigger

HTxxx & HTMxxx & STxxx Series

Description

The HTM, HT, and ST series of bilateral trigger DIACs offer

a range of voltage characteristics from 27V to 70V. A DIAC

semiconductor is a full-wave or bidirectionalThyristor. It is

triggered from a blocking state to a conduction state for

either polarity of applied voltage whenever the amplitude of

applied voltage exceeds the breakover voltage of the DIAC.

Applications

DIACs are used to triggerTriacs and SCRs in phase control

circuits for lamp dimming, universal motor speed control,

and heat control. They are used also for triggering

transistors in solid state ballast lighting controls.
