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