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 I
GT
 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.
