Onsemi Zener diode - difference between SZMMSZ and MMSZ series


Can any one please explains the di difference between family series SZMMSZ and MMSZ. The are exactly the same, so why different part numbers?


I have read in the data sheet an explanation of the SZ prefix

  • SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements

I think this resolve the inquiry.

Hello @ammar.al-latifi

You are correct this is for the Automotive rating. Here is a snip from the datasheet as a reference for additional users who read this post.


Thank you Robert for your reply and addition of the data sheet.
