Lxx04xx & Qxx04xx Series
Thyristors
4 Amp Sensitive & Standard Triacs
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
• RoHS-compliant
• Glass – passivated
junctions
• Voltage capability up to
1000 V
• Surge capability up to
55 A
• The L-package has
an isolation rating of
2500VRMS
• Solid-state switching
eliminates arcing or
contact bounce that
create voltage transients
• 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 short gate
activation pulse in each
half-cycle
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.
