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.
On-state RMS current: 25 A
Blocking voltage: 1200 V
High static community and dynamic commutation
IGT = 50 mA
High endurance reliability
Compact high voltage device
Applications
Motor control circuits
Heating control circuits
