Description

Available in TO220AB-Ins. (ceramic insulated),
the T1620T-8I, and T1635T-8I Triacs can be used
as on/off or phase angle function controllers in
general purpose AC switching.

These devices can be used without snubber (R +
C networks) if the datasheet limits are respected.

Provides insulation rated at 2500 V rms (TO­220AB insulated package).
