BTA312-800CT 3Q Hi-Com Triac 19 September 2018 Product data sheet 1. General description Planar passivated high commutation three quadrant triac in a SOT78 (TO-220AB) plastic package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This "series CT" triac will commutate the full RMS current at the maximum rated junction temperature (Tj = 150 °C) without the aid of a snubber. It is used in applications where "high junction operating temperature capability" is required. 2. Features and benefits 3Q technology for improved noise immunity High commutation capability with maximum false trigger immunity High immunity to false turn-on by dV/dt High junction operating temperature capability High voltage capability Less sensitve gate for high noise immunity Planar passivated for voltage ruggedness and reliability Triggering in three quadrants only 3. Applications Applications subject to high temperature Electronic thermostats (heating and cooling) High power motor controls e.g. washing machines and vacuum cleaners Rectifier-fed DC inductive loads e.g. DC motors and solenoids 4.
