4 Amp Sensitive & Standard Triacs
Lxx04xx & Qxx04xx Series
RoHS
Description
The Lxx04xx and Qxx04xx are 4 Amp bidirectional solid
state switch series. They are 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.
Features & Benefits
• Restricted (or limited) RFI
generation, depending on
activation point of
sine wave
• Surge capability up to
55 A
Agency Approval
Agency
• The L-package has
an isolation rating of
2500VRMS
Agency File Number
E71639
• Solid-state switching
eliminates arcing or
contact bounce that
create voltage transients

Design Considerations
Temperature/Humidity
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.
