Description
The WTA20 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
WTA20 Triacs provide a superior performance in
surge current handling capabilities.
By using an internal ceramic pad, the WTA series
provides voltage insulated tab (rated at
2500Vrms)
