Onsemi Zener diode - difference between SZMMSZ and MMSZ series

Hi,

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

Thanks

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.

Thanks

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.
