Planar passivated high commutation three quadrant triac in a TO92 (SOT54) plastic package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This series triac will commutate the full rated RMS current at the maximum rated junction temperature without the aid of a snubber.

Features and Benefits
• 3Q technology for improved noise immunity
• High blocking voltage capability
• High commutation capability with maximum false trigger immunity
• High immunity to false turn-on by dV/dt
• Less sensitive gate for high noise immunity
• Planar passivated for voltage ruggedness and reliability
• Triggering in three quadrants only
• General purpose motor control circuits
• Home appliances
• Solenoid drivers
