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 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.
2. Features and benefits
•
•
•
•
•
•
•
•
3Q technology for improved noise immunity
High commutation capability with maximum false trigger immunity
High immunity to false turn-on by dV/dt
High junction operating temperature capability
High voltage capability
Less sensitive gate for high noise immunity
Planar passivated for voltage ruggedness and reliability
Triggering in three quadrants only
3. Applications
