DESCRIPTION
Available in high power packages, the BTA/
BTB40-41 series is suitable for general purpose
AC power switching. They can be used as an ON/
OFF function in applications such as static relays,
heating regulation, water heaters, induction motor
starting circuits, welding equipment... or for phase
control operation in high power motor speed con-
trollers, soft start circuits...
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 2500 V
RMS) complying with UL standards (File ref.:
E81734).
