ht-32b

Manufacturer Part Number
ht-32b
Description
Diac Ht And St Series
Manufacturer
Littelfuse, Inc.
Datasheet
E8
General Description
Teccor’s HT and ST Series of bilateral trigger diacs offer a range
of voltage characteristics from 27 V to 70 V.
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 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.
