Hello Robert,


Had a tolerance issue with MMSZ4690 zeners and the manufacturing plant in China said they were quoted 8 weeks for replacement reels. Of course, that won't work.

Does anyone know a brand that is easily obtained in China and offers low current zeners? What I am looking for is a 5.6V version in SOD-123 package that likes running at 200uA. I am going to look for US sources now but that would mean several extra days to get them there.

Central Semi has a few lines of low current spec zeners.



Yes, they do. CMHZ4626, but non-stock everywhere I checked. I found some others as well but lead times are as high as 18wks and we need them pretty much right now :-(

Then get a sample of the same part withthe higher current spec and check on the curvetracer.
Maybe you will get lucky and find the high current part behaves at the low end.
Some parts get a different partnumber if pass into a different bin.
