8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs
Lxx08xx & Qxx08xx & Qxx08xHx Series
Description
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.
Alternistor
type devices 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.
Alternistor Triacs (no snubber required) are used in
applications with extremely inductive loads requiring
highest commutation performance.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
