1N988B - 500mW SILICON ZENER DIODES

Download the 1N988B datasheet PDF. This datasheet also covers the 1N957B variant, as both devices belong to the same 500mw silicon zener diodes family and are provided as variant models within a single manufacturer datasheet.

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.
