3Q Hi-Com Triac
12 September 2018
Product data sheet
1. General description
Planar passivated high commutation three quadrant triac in a SOT186A (TO-220F) "full pack"
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 (T
j(max)
= 150 °C) without the aid of a snubber. It is used in applications where "high
junction operating temperature capability" is required.
