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

Schematic Symbol
Typical applications are AC solid-state switches, power
tools, home/brown goods and white goods appliances.
Sensitive gate Triacs 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.
