Sensitive Triacs
(0.8 A to 8 A)
E1
General Description
Teccor's line of sensitive gate triacs includes devices with current
capabilities through 8 A. Voltage ranges are available from 200 V
to 600 V. This line features devices with guaranteed gate control
in Quadrants II and IV as well as control in the commonly used
Quadrants I and III. Four-quadrant control devices require
sensitive gate triacs. They can be controlled by digital circuitry
where positive-only or negative-only pulses must control AC
current in both directions through the device. Note that triacs with
low IGT values in Quadrants II and IV will have lower dv/dt
characteristics.
The sensitive gate triac is a bidirectional AC switch and is gate
controlled for either polarity of main terminal voltage. It is used
primarily for AC switching and phase control applications such as
motor speed controls, temperature modulation controls, and
lighting controls.
The epoxy TO-92 and TO-220 configurations feature Teccor's
electrically-isolated construction where the case or mounting tab
is internally isolated from the semiconductor chip and lead
attachments. Non-isolated epoxy TO-202 packages are available
as well as TO-251 and surface mount TO-252 (D-Pak). Tape-
and-reel capability and tube packing also are available. See
“Packing Options” section of this catalog.
All Teccor triacs have glass-passivated junctions. This glassing
process prevents migration of contaminants and ensures long-
term device reliability with parameter stability.
Variations of devices covered in this data sheet are available for
custom design applications. Consult factory for more information.

devices, -40 °C to +150 °C for TO-202 devices, and -40 °C to
+125 °C for TO-220 devices.
• Lead solder temperature is a maximum of 230 °C for 10 seconds
maximum at a minimum of 1/16” (1.59 mm) from case.
• The case or lead temperature (TC or TL) is measured as shown on

Gate Characteristics
Teccor triacs may be turned on between gate and MT1 terminals
in the following ways:
• In-phase signals (with standard AC line) using Quadrants I
and III
• Application of unipolar pulses (gate always positive or nega-
tive), using Quadrants II and III with negative gate pulses and
Quadrants I and IV with positive gate pulses
When 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).
