I have this Zener diode - 12V rated C part.
I just want to understand how to read the differential resistance column on table 8 for Zener current of 1mA and 5mA.
Suppose I give an input voltage of 16V across the 12V rated Zener diode. Let's assume that the series resistor is of appropriate value so as to focus on this understanding of the concept.
Let's also assume that the circuit is designed with proper series resistor for a certain load current.
How to read the differential resistance column on the table 8 with respect to the working voltage column? Like when to use the 1mA zener differential resistance column value and when to use the 5mA zener differential resistance column value?
For example, let us assume the 12V zener is in the breakdown region by applying 16V to the 12V Zener. What happens if I supply a Zener current of which is between the mentioned Zener currents in the differential resistance column of the datasheet , say for example a Zener current of 3mA or 15mA? How to find the Zener voltage when I supply these Zener currents?
In certain Zener diode datasheets, they provide the minimum Zener current required to make the Zener enter into the breakdown region. But in this datasheet, no such minimum current is provided. Why have not provided and how to find the minimum current at which the 12V Zener will enter into the breakdown region if I have applied 16V?
