4Q Triac 30 August 2013 Product data sheet 1. General description
Planar passivated sensitive gate four quadrant triac in a SOT78 (TO-220AB) plastic
package intended for use in general purpose bidirectional switching and phase control
applications. This sensitive gate "series E" triac is intended to be interfaced directly to
microcontrollers, logic integrated circuits and other low power gate trigger circuits. 2. Features and benefits
