I am using the following circuit for over voltage protection
The zener breaks down at approx 9.5V
When I connect the load and only when the load draws more current (arount 4 to 5 Amps maybe- Its a fast changing load and hence finding exact current is difficult as I have only a basic multimeter), the zener breaks down and the MOSFET goes off.
How can I stop this from happening.
What parameters of the zener or mosfet I will have to look for to make sure that the over voltage works fine.
