Overview
Teccor® brand Thyristors 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 bidirectional Thyristor.
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.
