Teccor® brand Thyristors
12 Amp Alternistor (High Communitation) Triacs
Agency File Number
L Package: E71639
400 to 1000
10 to 50
12 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.
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
• Voltage capability up to
• Surge capability up to
• Electrically isolated
“L-Package” is UL
• Solid-state switching
eliminates arcing or
contact bounce that
create voltage transients
• No contacts to wear
out from reaction of
• Restricted (or limited) RFI
on activation point sine
• Requires only a small
gate activation pulse in
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, lawn care equipment, 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.
