ST36A Datasheet, PDF (1/8 Pages) Littelfuse – Standard Bidirectional DIAC Trigger

Teccor^® brand Thyristors
Standard Bidirectional DIAC Trigger
HTxxx & HTMxxx & STxxx Series
Schematic Symbol
Applications
DIACs are used to trigger Triacs and SCRs in phase control
circuits for lamp dimming, universal motor speed control,
and heat control. They are used also for triggering
transistors in solid state ballast lighting controls.
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.
