4 Amp Sensitive & Standard Triacs
Lxx04xx & Qxx04xx Series
Description
4 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.

Applications
Schematic Symbol
Typical applications are AC solid-state switches, power
tools, home/brown goods and white goods appliances.
Sensitive gateTriacs can be directly driven by
microprocessor or popular opto-couplers/isolators.
