HT and ST Series
E8
General Description
Teccor 's HT and ST Series of bilateral trigger diacs offer a range of voltage characteristics from 27 V to 45 V. A diac semiconductor is a full-wave or bidirectional thyristor. It is triggered from a blocking- to conduction-state for either polarity of applied voltage whenever the amplitude of applied voltage exceeds the breakover voltage rating of the diac. The Teccor line of diacs features glass-passivated junctions to ensure long-term reliability and parameter stability. Teccor's glass offers a rugged, reliable barrier against junction contamination. The diac specifications listed in this data sheet are for standard products. Special parameter selections such as close tolerance voltage symmetry are available. Consult the factory for more information about custom design applications.

Electrical Specification Notes
(1) (2) (3) Breakover voltage symmetry as close as 1 V is available from the factory on these products. See Figure E8.4 and Figure E8.5 for test circuit and waveforms. Typical switching time is 900 nano-seconds measured at IPK (Figure E8.4) across a 20 W resistor (Figure E8.5). Switching time is defined as rise time of IPK between the 10% to 90% points. See V-I Characteristics.
