GA1A2DESCRIPTION
Available either in through-hole or surface-mountpackages, the BTA10 and BTB10 triac series issuitable for general purpose AC switching. Theycan be used as an ON/OFF function in applica-tions such as static relays, heating regulation, in-duction motor starting circuits... or for phasecontrol operation in light dimmers, motor speedcontrollers,...
The snubberless version (W suffix) is speciallyrecommended for use on inductive loads, thanksto their high commutation performances.
By using an internal ceramic pad, the BTA seriesprovides voltage insulated tab (rated at2500VRMS) complying with UL standards (File ref.:E81734).
