Planar passivated Temperature and Overload Protected Triac with high commutation performance in a SOT78 (TO-220AB) plastic package. This TOPTriac conveniently self protects by turning off in the event of excessive temperature. It is triggered negatively using continuous DC or current pulses.

Features and Benefits
  • Exclusive negative gate triggering
  • Full cycle AC conduction
  • Hi-Com technology gives maximum immunity to false triggering
  • High immunity to false turn-on by dV/dt
  • High minimum IGT for guaranteed immunity to gate noise
  • Over-temperature self protection function
  • Pin compatible with standard triacs
  • Planar passivated for voltage ruggedness and reliability
  • Any circuit where protection against overload and/or over temperature is required
  • Motor controls and starters – e.g. refrigeration compressors
  • High power density motors – e.g. vacuum cleaners, window blinds, food processors
  • Heating and cooking appliances
  • Water boilers
