Quadrac

Internally Triggered Triacs (4 A to 15 A)

General Description

Teccor’s Quadrac devices are triacs that include a diac trigger

mounted inside the same package. This device, developed by

Teccor, saves the user the expense and assembly time of buying

a discrete diac and assembling in conjunction with a gated triac.

Also, the alternistor Quadrac device (QxxxxLTH) eliminates the

need for a snubber network.

The Quadrac device is a bidirectional AC switch and is gate con-

trolled for either polarity of main terminal voltage. Its primary pur-

pose is for AC switching and phase control applications such as

speed controls, temperature modulation controls, and lighting

controls where noise immunity is required.

Triac current capacities range from 4 A to 15 A with voltage

ranges from 200 V to 600 V. Quadrac devices are available in the

TO-220 package.

The TO-220 package is electrically isolated to 2500 V rms from

the leads to mounting surface. 4000 V rms is available on special

order. This means that no external isolation is required, thus

eliminating the need for separate insulators and insulator-mount-

ing steps and saving dollars over “hot tab” devices.

All Teccor triac and diac chips have glass-passivated junctions to

ensure long-term device reliability and parameter stability.

Variations of devices in this data sheet are available for custom

design applications. Consult the factory for more information.

Features

• Glass-passivated junctions

• Electrically-isolated package

• Internal trigger diac

• High surge capability — up to 200 A

• High voltage capability — 200 V to 600 V
