TRIACS

DESCRIPTION

Glass passivated triacs in a full pack plastic envelope, intended

for use in applications requiring high bidirectional transient and

blocking voltage capability and high thermal cycling performance.

Typical applications include motor control, industrial and

domestic lighting, heating and static switching.

*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.
