Product data sheet
1. General description
Planar passivated high commutation three quadrant triac in a SOT78 (TO-220AB) plastic package
intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This
"series BT" 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.
