HT-32A - Littelfuse

HT-32A Thyristors

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. .
