General description

Planar passivated high commutation three quadrant triac in a SOT78D (IITO-220) internally insulated plastic package. This triac is intended for use in motor control circuits where high blocking voltage, high static and dynamic dVD/dt as well as high dIcom/dt can occur. This series C0T triac will commutate the full rated RMS current at the maximum rated junction temperature without the aid of a snubber. This device has high operating capability (Tj(max) = 150 °C) and an internally isolated mounting base.

Features and benefits

• 3Q technology for improved noise immunity

• High commutation capability with maximum false trigger immunity

• High junction operating temperature capability (Tj(max) = 150 °C)

• High immunity to false turn-on by dV/dt

• High voltage capability

• Less sensitive gate for very high noise immunity

• Planar passivated for voltage ruggedness and reliability

• Triggering in three quadrants only

• Internally insulated package

• Isolated mounting base with 2500 V (RMS) isolation

Applications

• Applications subject to high temperature (Tj(max) = 150 °C)

• Compressor starting control circuits

• General purpose motor controls

• Reversing induction motor controls e.g. vertical axis washing machines
