Lx01Ex & LxNx & Qx01Ex & QxNx Series
Description
1 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
Excellent for lower current heating controls, water valves,
and solenoids.
Typical applications are AC solid-state switches, home/
brown goods and white goods appliances.
Sensitive gate Triacs can be directly driven by
microprocessor or popular opto-couplers/isolators. MT2 MT1
