12 Amp Alternistor (High Communitation) Triacs
Qxx12xHx Series
Description
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.

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.
