Planar passivated sensitive gate four quadrant triac in a SOT78 (TO-220AB) plastic package intended for use in general purpose bidirectional switching and phase control applications. This sensitive gate "series E" triac is intended to be interfaced directly to microcontrollers, logic integrated circuits and other low power gate trigger circuits.

Features and Benefits
  • Direct triggering from low power drivers and logic ICs
  • High blocking voltage capability
  • Planar passivated for voltage ruggedness and reliability
  • Sensitive gate
  • Triggering in all four quadrants
  • General purpose motor control
  • General purpose switching
