Teccor® brand Thyristors
15 Amp Standard & 16 Amp Alternistor (High Commutation) Triacs
Qxx15xx & Qxx16xHx Series
Description
15 Amp and 16 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.
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.

Typical applications are AC solid-state switches, light
dimmers, power tools, lawn care equipment, home/brown
goods and white goods appliances.
MT1
Alternistor Triacs (no snubber required) are used in
applications with extremely inductive loads requiring
highest commutation performance.
G
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
