4 Amp High Temperature Sensitive & Standard Triacs
RoHS
LJxx04xx & QJxx04xx Series
Description
This 4 A HighTemperatureTriac 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 components guarantee gate control in
Quadrants I & IV needed for digital control circuitry.
Standard type components normally operate in Quadrants
I & III triggered from AC line.
Features & Benefits
• RoHS Compliant
• No contacts to wear out
from reaction of switching
events
• 150°C maximum junction
temperature

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.
