T4050-6PF – 600V snubberless triac from STMicroelectronics

The T4050-6PF is a modern triac in an insulated housing, optimized for work with inductive loads without the use of an external RC gauze system (snubberless). Typical applications are relays, heating control, induction motor starter circuits, light dimmers, motor speed controllers and many other industrial applications where high resistance and high surge current are required.

Main features:

  • High-current triac = 40A
  • High surge current = 400A
  • Max. blocking voltage = VDRM, VRRM = 600V
  • Max. surge voltag= VDSM, VRSM = 700V
  • Max. Igt = 50mA
  • High static and dynamic commutation:
    • dI/dt = 25,1A/ms
    • dV/dt = 1000 V/us
  • L1557 certificate (signature Akt 81734) = 2,5 kV
  • Snubberless type device
  • Compliant with ECOPACK2 (RoHS and HF compliance)
  • TO3-PF housing
