Product data sheet
1. General description
Planar passivated 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
Low holding current for low current loads and lowest EMI at commutation
Planar passivated for voltage ruggedness and reliability
Triggering in all four quadrants
Very sensitive gate for easy logic level triggering
3. Applications
•
•
General purpose motor control
General purpose switching
