Greetings,
I am trying to base my design around Sabre SD and I found this to be confusing;
For the regulation Zener current is 20mA however resistor 5/2700 = 1.8mA.
Am I missing something or is this a wrong implementation?
Best Regards,
Mete

Hi Atilla
overvoltage protection does not require high accuracies and according
to zener datasheet below it works fine down to 1-2mA.

Hello Igor,
I guess you are right, for MMSZ5221BT1 the graph is like this;
Thank you for reminding me to check the graph first.
