General Description
These gated triacs from Teccor Electronics are part of a broad
line of bidirectional semiconductors. The devices range in current
ratings from 0.8 A to 35 A and in voltages from 200 V to 1000 V.
The triac may be gate triggered from a blocking to conduction
state for either polarity of applied voltage and is designed for AC
switching and phase control applications such as speed and tem-
perature modulation controls, lighting controls, and static switch-
ing relays. The triggering signal is normally applied between the
gate and MT1.
Isolated packages are offered with internal construction, having
the case or mounting tab electrically isolated from the semicon-
ductor chip. This feature facilitates the use of low-cost assembly
and convenient packaging techniques. Tape-and-reel capability
is available. See “Packing Options” section of this catalog.
All Teccor triacs have glass-passivated junctions to ensure long-
term device reliability and parameter stability. Teccor's glass-pas-
sivated junctions offer a rugged, reliable barrier against junction
contamination.
Variations of devices covered in this data sheet are available for
custom design applications. Consult factory for more information.

In all cases, if maximum surge capability is required, pulses
should be a minimum of one magnitude above IGT rating with a
steep rising waveform (1 µs rise time).

Electrical Isolation
www.DataSheet4U.com
Teccor’s isolated triac packages will withstand a minimum high
potential test of 2500 V ac rms from leads to mounting tab or
base, over the operating temperature range of the device. The
following isolation table shows standard and optional isolation
ratings.
