Teccor brand Thyristors 4 / 6 / 8 / 10 / 15 Amp Quadracs RoHS QxxxxLTx Series Description 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 t ype Quadracs are used in circuits requiring high dv/dt capability.

Typical applications are AC MT2 MT1 solid-state switches, light dimmers, power tools, home/ brown goods and white goods appliances. Alternistor Quadracs (no snubber required) are used in T applications with extremely inductive loads requiring highest commutation performance. Main Features Internally constructed isolated package is offered for ease of heat sinking with highest isolation voltage.
