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

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.
