Product data sheet
1. General description
Planar passivated high commutation three quadrant triac in a IITO-220 internally insulated plastic
package. This "series ET" triac balances the requirements of commutation performance and gate
sensitivity and is intended for interfacing with low power drivers including microcontrollers. It is
used in applications where " high juction operating temperature " capability is required.
