8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs
Lxx08xx & Qxx08xx & Qxx08xHx Series
®
Description
8 Amp bi-directional 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 devices guarantee gate control in Quadrants
I & IV needed for digital control circuitry.
Standard type devices normally operate in Quadrants I & III
triggered from AC line.
Alternistor type devices only operate in quadrants I, II, & III
and are used in circuits requiring high dv/dt capability.

Features & Benefits
• RoHS compliant
• Glass – passivated
junctions
• Voltage capability up
to 1000 V
• Surge capability up
to 100 A
• Electrically isolated
“L-Package” is UL
recognized for 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 small gate
activation pulse in 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.
