... Standard Bidirectional DIAC Trigger 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 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 & ...

... Design Considerations Careful selection of the correct device for the application’s operating parameters and environment will go a long way toward extending the operating life of the Thyristor. Overheating and surge currents are the main killers of DIACs. Correct mounting, soldering, and forming of the leads also help protect against component damage. Dimensions – ...
