I am using a MOSFET as a pre-regulator.
When the voltage is too high, the temperature of the MOSFET is getting too high. (Even if I take 15 mA current.)
As a safety precaution, if the junction temperature of the MOSFET exceeds 100 degrees, I want it to enter the cut-off region. What are your suggestions?
(Note:I am using a iron cooler.But still, there is a rise in temperature.)
