Hello,
Please indentify this SMA(DO-214AC) packaging rectifier. I can’t find what is it.
The open voltage is 0,570V.
Hello @oszitrek,
Thank you for your inquiry.
I am only able to narrow down our options to a certain point with that image and information.
If it’s a TVS diode, it might be this guy:
- SMA6J11A-TP Unidirectional TVS 11V 600W
The 11V value is very uncommon, but I would say that in most circumstances, the more common 12V value would do just fine. We have a number of 12V options if you think that would be acceptable.

Maybe this, but I think this is not MCC. And can other manufacturers use the SMD markings differently?
This is a SMA6J15A from MCC. Laser engraving is clearly completely different.
Hello @oszitrek
There are other manufacturers with the KZ marking but SMB package case size:
SMA (5.59x2.92mm) vs SMB (5.59x3.81mm)
Littelfuse SMBJ11CALFCT-ND

Bourns SMBJ11CABCT-ND

Taiwan Semiconductor SMBJ11CAFSCT-ND

Hi oszitrek,
I have checked datasheets from multiple (at least a dozen) vendors, and the marking “KZ” universally seems to represent a stand-off voltage of 11V. I can’t say which particular vendor made your original part, but I am pretty confidant that it is an 11V part.
Regarding whether it’s an SMA package or an SMB package (your image appears to be of an SMA to me), @Troy_2808 gives you dimensions to determine whether it is an SMA or SMB.
Here are some drawings of each to further compare (note the difference in highlighted dimension):
SMA (DO-214AC)
SMB (DO-214AA)
As this is somewhat of a commodity part, choosing any of the 11V parts would likely work for you from either the SMA or the SMB parts, depending on which size part you actually have.
