QJxx30LH4 Series - 30 Amp High Temperature Alternistor Triacs

Roll Over to Zoom

This 30A high temperature Alternistor TRIAC, offered in TO-220 isolated package has 150°C maximum junction temperature and 350A 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 800V 
  • Surge capability of 350A at 60Hz half cycle
  • Mechanically and thermally robust TO-220 clip-attach assembly
  • Electrically isolated for 2500Vrms 
  • 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.
