6 Amp High Temp Sensitive & Alternistor (High Commutation) Triacs
RoHS
LJxx06xx & QJxx06xHx series
Description
This 6 A HighTemperature AlternistorTriac 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.
Alternistor type components only operate in quadrants
I, II, & III and are used in circuits requiring high dv/dt
capability.

Applications
MT2
MT1
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.
G
AlternistorTriacs (no snubber required) are used in
applications with high inductive loads requiring the highest
commutation performance.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
