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 B" triac will commutate the full rated RMS current at the maximum rated junction
temperature without the aid of a snubber.
2. Features and benefits
•
•
•
•
•
•
•
•
•
3Q technology for improved noise immunity
High immunity to false turn-on by dV/dt
High minimum IGT for guaranteed immunity to gate noise
High voltage capability
Isolated mounting base package
Least sensitive gate for highest noise immunity
Planar passivated for voltage ruggedness and reliability
Triggering in three quadrants only
Very high commutation capability with maximum false trigger immunity
3. Applications
