Description
The T2550-12x is a 25 A 1200 V Snubberless Triac available in three packages:
D²PAK, TO-220AB and TO-220AB insulated.
Its 1200 V blocking voltage enables use in 3-phase industrial application. Its noise
immunity and dynamic commutation makes it suitable for either inductive, capacitive
or resistive load control.
