8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs
Lxx08xx & Qxx08xx & Qxx08xHx Series
Main Features
Description
This 8 Amp bidirectional 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 as needed for digital control circuitry.
Standard type components normally operate in Quadrants
I & III triggered from AC line.
Alternistor type components only operate in quadrants I, II,
& III and are used in circuits requiring high dv/dt capability.
Symbol Value Unit
IT(RMS) 8 A
VDRM/VRRM 400, 600, 800 or 1000 V
IGT (Q1) 5 to 50 mA
Features & Benefits
• RoHS compliant
• Glass – passivated
junctions
• Voltage capability up
to 1000 V
• Surge capability up
to 100 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 a short gate
activation pulse during
each half-cycle
Applications
Excellent for AC switching and phase control applications
such as heating, lighting, and motor speed controls.
Typical applications are AC solid-state switches, light
dimmers, power tools, home/brown goods and white
goods appliances.
Alternistor Triacs (no snubber required) are used in
applications with extremely inductive loads requiring
highest commutation performance.
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.
