LxX8Ex & LxXx & QxX8Ex & QxXx Series

0.8 Amp Sensitive & Standard Triacs

LxX8Ex & LxXx & QxX8E & QxXx Series

Description

0.8 Amp bi-directional solid state switch series is designed

for AC switching and phase control applications such as

motor speed and temperature modulation controls, lighting

controls, and static switching relays.

Sensitive type devices guarantee gate control in Quadrants

I & IV needed for digital control circuitry.

Standard type devices normally operate in Quadrants I & III

triggered from AC line.

Features

600 V

10 A

Applications

Excellent for lower current heating controls, water valves,

and solenoids.

Typical applications are AC solid-state switches, home/

brown goods and white goods appliances.

microprocessor or popular opto-couplers/isolators.
