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 voltages and static switching.

Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. 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.
