DESCRIPTION
Available in high power packages, the
BTA/
BTB40-41
series is suitable for general purpose
AC switching. They can be used as an ON/OFF
function in applications such as static relays, heat-
ing regulation, induction motor starting circuits… or
for phase control operation in light dimmers, motor
speed controllers, …

Thanks to their clip assembly technique, they
provide a superior performance in surge current
handling capabilities.
By using an internal ceramic pad, the BTA series
provides voltage insulated tab (rated at
2500V
RMS
) complying with UL standards (File ref.:
E81734).
