Reverse Leakage Current of Zener Diode BZX84C39

[sujithganesan]

Hi All,

I have a query regarding the reverse leakage current relation with reverse voltage of Zener diode. In datasheet I could only get information that max reverse leakage current at reverse voltage of 0.7Vznom is 50nA. I need to know the values of reverse leakage current for reverse voltage values between 0.7Vznom i.e. 27.3V to Zener breakdown voltage of 37V. I am not able to get the detail from graph also. Please help.

I have attached the datasheet I am referring to for reference. PFA.

Search NXP's size for "BZX84 spice" and then download the nearest Spice Model to the one you're interested in. Run that under Spice (LTSpice is easy to use) and get it to tell you those values.

Then ignore them. The manufacturer is free to change any and all device parameters that aren't in the Data Sheet, or within the very wide limits imposed by the Data Sheet. Which says "50nA Max at 23.1V" for the Reverse Leakage of the 33V part. So they can produce parts anywhere in the range of 0-50nA and be compliant with the Data Sheet.

If your design depends on an "undocumented parameter", then change the design. Do it some other way. Otherwise you're likely to have to replace over 2000 zener diodes by hand from a different reel in order to ship and sell the things you're making.

I was looking similliar actions for semiconductor diode characteristics and i need to talk to nexperia aswell.

Hi Sujith,

Thanks for your inquiry. This question is related to the Standard Products business. We would like to inform you that NXP has divested it´s Standard Products business on Feb 6th 2017. This new standalone company is called “Nexperia”, headquartered in the Netherlands, and is a world-class leader in Discretes, Logic and MOSFETs.

We would like to ask you to re-enter your inquiry at the Nexperia support web page: www.nexperia.com/support. Thank you!

Best regards,
