TFA38 - Reverse Blocking Triode Thyristor

Download the TFA38 datasheet PDF. This datasheet also covers the TFA37 variant, as both devices belong to the same reverse blocking triode thyristor family and are provided as variant models within a single manufacturer datasheet.

General Description

This Sanken reverse blocking triode thyristor is designed for AC power control, providing reliable, uniform switching for half-cycle AC applications.

In comparison with other products on the market, the TFA3x series provides increased isolation voltage (1800 VACRMS), guaranteed for up to 1 minute.

Key Features

  • Exceptional reliability.
  • Small fully-molded SIP package with heatsink mounting for high thermal dissipation and long life.
  • Operating junction temperature to 150°C.
  • VDRM of 700 or 800 V.
  • 4.7 ARMS on-state current.
  • 7 mA typical gate trigger current.
  • Uniform switching.
  • UL Recognized Component (File No. : E118037) (suffix I).
