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).
