General description

Planar passivated high commutation three quadrant triac in a SOT78 plastic package. The series ET triac balances the requirements of commutation performance and gate sensitivity. The sensitive gate series ET is intended for interfacing with low power drivers including microcontrollers where high junction operating temperature capability is required.

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 sensitive gate

• High junction operating temperature capability

• High voltage capability

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

Applications

• Applications subject to high temperature

• Electronic thermostats (heating and cooling)

• High power motor controls e.g. washing machines and vacuum cleaners

• Refrigeration and air-conditioner compressor controls
