Download the 1N4686UR datasheet PDF.
This datasheet also covers the 1N4678 variant, as both devices belong to the same zener diodes 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.
Note: The manufacturer provides a single datasheet file (1N4678-DigitronSemiconductors.pdf) that lists specifications for multiple related part numbers.
