Planar passivated high commutation three quadrant triac in a SOT78D (TO-220AB) internally insulated 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(max)] = 150 °C) without the aid of a snubber. It is used in applications where "high junction operating temperature capability" is required.
