4 Amp High Temperature Sensitive & Standard Triacs
LJxx04xx & QJxx04xx Series
RoHS
Description
This 4 A High Temperature Triac 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
• 150°C maximum junction
temperature

• Voltage capability up to
600V
• Surge capability up to
48A at 60HZ half cycle
• Solid-state switching
eliminates arcing or
contact bounce that
create voltage transients
Schematic Symbol
• No contacts to wear out
from reaction of switching
events
• Restricted (or limited) RFI
generation, depending on
activation point of
sine wave
• Requires only a small gate
activation pulse in each
half-cycle
• Halogen free and RoHS
compliant
Applications
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.

Design Considerations
Careful selection of the correct component for the application’s operating
parameters and environment will go a long way toward extending the
operating life of the Thyristor. Good design practice should limit the
maximum continuous current through the main terminals to 75% of the
component rating. Other ways to ensure long life for a power discrete
semiconductor are proper heat sinking and selection of voltage ratings for
worst case conditions. Overheating, overvoltage (including dv/dt), and surge
currents are the main killers of semiconductors. Correct mounting, soldering,
and forming of the leads also help protect against component damage.
