General description
Planar passivated high commutation three quadrant triac in a SOT78 plastic package. This "series D" triac balances the requirements of commutation performance and gate sensitivity. The "very sensitive gate" "series D" is intended for interfacing with low power drivers including microcontrollers.

Features and benefits
■ 3Q technology for improved noise immunity
■ Direct interfacing with low power drivers and microcontrollers
■ Good immunity to false turn-on by dV/dt
■ High commutation capability with very sensitive gate
■ High voltage capability
■ Planar passivated for voltage ruggedness and reliability
■ Triggering in three quadrants only

Applications
■ Electronic thermostats (heating and cooling)
■ High power motor controls e.g. washing machines and vacuum cleaners
