1. General description
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 (T
j(max)
= 150 °C) without the
aid of a snubber. It is used in applications where "high junction operating temperature
capability" is required.
