4 Amp Sensitive & Standard Triacs
RoHS
Lxx04xx & Qxx04xx Series
Description
The Lxx04xx and Qxx04xx are 4 Amp bidirectional solid
state switch series. They are 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 as needed for digital control circuitry.
Standard type devices normally operate in Quadrants I & III
triggered from AC line.

Sensitive gateTriacs can be directly driven by
microprocessor or popular opto-couplers/isolators.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
