This 25A high temperature Alternistor TRIAC, offered in TO-220AB, TO-220 isolated and TO-263, as well as robust TO-218 Isolated and TO-218X isolated with loop lead.

This TRIAC has 150C maximum junction temperature and 250A ITSM(60Hz). 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, & III and offers high performance in applications requiring high commutation capability.

Features:

  • High TJ of 150°C
  • Voltage capability up to 600V
  • Surge capability of 250A at 60Hz half cycle
  • Mechanically and thermally robust TO-220 and TO-218 clip-attach assembly
  • Internally-isolated TO-220 and TO-218 packages
  • Halogen free and RoHS compliant

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 as compressor motor control

Alternistor TRIAC is used with high inductive loads requiring the high commutation capability. Internally isolated packages offer better heat sinking with higher isolation voltage.
