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.

Features & Benefits:

  • High TJ of 150°C
  • Voltage capability of 600 V
  • Surge capability of 153 A
  • Mechanically and thermally robust TO-220 clip-attach assembly
  • Internally-isolated TO-220 package
  • Halogen-free and RoHS-compliant
  • High dv/dt up to 1000 V/μs


  • 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.
