Littelfuse ST-35

The HTM, HT, and ST series of bilateral trigger DIACs offer a range of voltage characteristics from 27V to 70V. 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.
