1. General description
Planar passivated very sensitive gate four quadrant triac in a SOT78 (TO-220AB)
plastic package intended for use in general purpose bidirectional switching and phase
control applications, where high sensitivity is required in all four quadrants. This very
sensitive gate "series D" triac is intended to be interfaced directly to microcontrollers,
logic integrated circuits and other low power gate trigger circuits.
2. Features and benefits
•
Direct triggering from low power drivers and logic ICs
•
High blocking voltage capability
•
Planar passivated for voltage ruggedness and reliability
•
Triggering in all four quadrants
•
Very sensitive gate
3. Applications
•
General purpose phase control
•
General purpose switching
