Description
This 16 A high temperature Alternistor TRIAC, offered in
TO-220AB, TO-220 isolated, and TO-263 packages, has 150 °C
maximum junction temperature (TJ) and 200 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.

Features & Benefits
■ High TJ of 150°C
■ Voltage capability of 600V
■ Surge capability of 200A at 60Hz half cycle
■ Mechanically and thermally robust TO-220 clip-attach assembly
■ High dv/dt up to 1000V/μs
■ Internally-isolated TO-220 package
■ Halogen-free and RoHScompliant
■ Recognized to UL 1557 as an Electrically Isolated Semiconductor Device

Applications
TRIAC is an excellent AC switch in applications such as heating,
lighting, and motor speed controls.
Typical applications are:
■ Heater control such as coffee brewer, tankless water heater, and
infrared heater
■ AC solid-state relays
■ Light dimmers including incandescent and LED lighting
■ Motor speed control in kitchen appliances, power tools, home/
brow/white goods and light industrial applications such as
compressor motor control
Alternistor TRIAC is used with high inductive loads requiring high
commutation capability. Internally isolated packages offer better heat
sinking with higher isolation voltage.
