Hi, I have been trying to calculate the wattage for a Zener / Resistor that clamps a input with these parameters
Peak voltage 30v DC (this is what it can get to sometimes)
Output voltage 5v (this is max what I want to on this input)
Output current 30mA (this is the maximum current sourced on this line)
This is to protect a input line.
I suspect because of my lack of knowledge I am getting some large values!
