TRIACS
DESCRIPTION
Passivated triacs in a 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 6A/µs.
