The Snubberless versions (BTA, BTB08_xxxxW and T8 series) are specially
recommended for use on inductive loads, thanks to their high commutation
performance.

Available either in through-hole and surface-mount packages, these devices are
suitable for general purpose AC switching. They can be used as an ON/OFF function
in applications such as static relays, heating regulation, induction motor starting
circuits or for phase control operation in light dimmers and motor speed controllers,
etc.
Logic level versions are designed to interface directly with low power drivers such as
Microcontrollers.
By using an internal ceramic pad, the BTA series provide voltage insulated tab (rated
at 2500 VRMS) in compliance with UL standards (file ref.: E81734).
