QVxx12xHx Series
12 A High Temperature Alternistor Triacs
RoHS
Description
This 12 A high temperature Alternistor TRIAC, offered in
TO-220AB, TO-220 isolated, and TO-263 packages, has 150 °C
maximum junction temperature (TJ) and 153 A ITSM (60 Hz).
This series enables easier thermal management and higher surge
handling capability in AC power control applications such as
heater control, motor speed control, lighting controls, and static
switching relays. Alternistor TRIAC operates in quadrants I, II, and
III, and offers high performance in applications requiring high
commutation capability.
