Description

The BTA20 Triacs use high performance glass

passivated chip technology. The Snubberless

concept offers suppression of the RC network and

is suitable for applications such as phase control

and static switching on inductive or resistive load.

Thanks to their clip assembly technique, the

BTA20 Triacs 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).
