1N6643 - SWITCHING RECTIFIERS

Download the 1N6643 datasheet PDF. This datasheet also covers the 1N6638 variant, as both devices belong to the same switching rectifiers family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number.
  • Available as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix.
