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 controllers, 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).
