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.
