Table 1: Main Features
DESCRIPTION
Based on ST’s Snubberless / Logic level technol-
ogy providing high commutation performances,
the T4 series is suitable for use on AC inductive
loads.
They are recommended for applications using
universal motors, electrovalves.... such as kitchen
aid equipments, power tools, dishwashers,...
Available in a fully insulated package, the T4...-
...W version complies with UL standards (ref.
E81734).
