TRIACS
DESCRIPTION
Glass passivated , sensitive gate triacs in a full plastic envelope,
intended for use in general purpose bidirectional switching and
phase control aplications, where high sensitivity is required in all
four quadrants.

*Although not recommended, off-state voltages up to 800V may be applied without damage, but the triac may
switch to the on-state. The rate of rise of current should not exceed 15A/µs.
