1200V 25A Snubberless™ Triac

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. The T2550-12 is available in three packages: D²PAK, TO-220AB and TO-220AB insulated.

Key Features

  • On-state current: 25 A
  • Blocking voltage: 1200 V
  • High static and dynamic commutation
  • IGT = 50 mA
