APPLICATIONS
Applications include the ON/OFF function in
applications such as static relays, heating
regulation, induction motor starting circuits,
etc., or for phase control operation in light
dimmers, motor speed controllers, and silmilar.
The snubberless versions are especially
recommended for use on inductive loads,
due to their high commutation performances.
The 25T series provides an insulated tab
(rated at 2500V
RMS
).
