1. Product profile
1.1 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.
1.2 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
1.3 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
