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 (BTA/BTB...W and T25
series) are especially recommended for use on
inductive loads, due to their high commutation
performances. The BTA series provides an
insulated tab (rated at 2500 V
RMS
).
