LxX8Ex & LxXx & QxX8Ex & QxXx Series
0.8 Amp Sensitive & Standard Triacs
0.8 A TRIACs
LxX8Ex & LxXx & QxX8E & QxXx Series
Description
0.8 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.
