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 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
