1. General description
Planar passivated sensitive gate four quadrant triac in an internally insulated SOT78D
(TO-220AB) plastic package intended for use in general purpose bidirectional switching
and phase control applications. This sensitive gate "series E" triac can be interfaced
directly to microcontrollers, logic integrated circuits and other low power gate trigger
circuits. The internally insulated mounting base gives good thermal performance
combined with ease of handling and assembly by the user.
