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. Features & Benefits t compliant ST Series: t &QPYZ4.QBDLBHF (DO-214) t )JHIUFNQFSBUVSF TPMEFS bonded die attachment HTM/HT Series: t .*/*.&-'%0USJHHFS package
