I have this – Zener Diode – 12V Reverse Voltage
On the table 8, I can see the ranges for the 12V reverse voltage is between 11.4V and 12.7V for the "C" selection part. But this value if for 5mA of zener reverse current.
But, if we see the characteristics of zener diode, we see the below graph,
We can see there is a minimum reverse zener current to enter the breakdown and there is a maximum zener current (above which, the device will get damaged).
But the datasheet table 8 , provides the value for a reverse zener current of 5mA only. But they didn't mention whether it is the minimum or the maximum zener current.
Question 1 :
I just want to know what is the minimum required zener current for the 12V "C" zener part so as to enter into the breakdown region? Where is it mentioned in the datasheet?
Question 2 :
On table 8, what does the 5th column, Reverse Current (uA) and VR indicate?
Please provide help.
