Description

Main Features

The Quadrac is an internally triggered Triac designed for

AC switching and phase control applications. It is a Triac

and DIAC in a single package, which saves user expense

by eliminating the need for separate Triac and DIAC

components.

Standard type devices normally operate in Quadrants I & III

triggered from AC line.

Alternistor type Quadracs are used in circuits requiring high

dv/dt capability.

Applications

Excellent for AC switching and phase control applications

such as lighting and heating. Typical applications are AC

solid-state switches, light dimmers, power tools, home/

brown goods and white goods appliances.

Alternistor Quadracs (no snubber required) are used in

applications with extremely inductive loads requiring

highest commutation performance.

Internally constructed isolated package is offered for ease

of heat sinking with highest isolation voltage.
