General description
AC Thyristor Triac power switch in a SOT404 (D2PAK) surface mountable plastic package with self-protective clamping capabilities against low and high energy transients. This "series CT" triac will commutate the full RMS current at the maximum rated junction temperature (Tj(max) = 150 °C) without the aid of a snubber. It is used in applications where "high junction operating temperature capability" is required.

FEATUREs and benefits
• Clamping structure ensuring safe high over-voltage withstand capability
• High junction operating temperature capability
• Full cycle AC conduction
• Over-voltage withstand capability to IEC 61000-4-5
• Pin compatible with standard triacs
• Planar passivated for voltage ruggedness and reliability
• Protective self turn-on capability for high energy transients
• Safe clamping capability for low energy over-voltage transients
• Less sensitive gate for high noise immunity
• Surface mountable package
• Triggering in three quadrants only
• Very high immunity to false turn-on by dV/dt

APPLICATIONs
• AC fan, pump and compressor controls
• Highly inductive, resistive and safety loads
• Large and small appliances (White Goods)
• Reversing induction motor controls
• Applications subject to high temperature
