8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs
RoHS
Lxx08xx & Qxx08xx & Qxx08xHx Series
Description
This 8 Amp bidirectional 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 components guarantee gate control in
Quadrants I & IV as needed for digital control circuitry.
Standard type components normally operate in Quadrants
I & III triggered from AC line.
Alternistor type components only operate in quadrants I, II,
& III and are used in circuits requiring high dv/dt capability.

Applications
Excellent for AC switching and phase control applications
such as heating, lighting, and motor speed controls.
Typical applications are AC solid-state switches, light
dimmers, power tools, home/brown goods and white
goods appliances.
