Why is a diode's thermal resistance quoted from junction to ambient?
Answer: A
The rating that actually destroys the device is junction temperature, and thermal resistance is what converts dissipated power into the rise above ambient. The forward drop and leakage are measured at stated temperatures but are not what the figure is for, and the surge rating is a separate specification. Any thermal calculation works backwards from the limiting temperature through the resistances to the power that may be allowed, which is why the path is specified end to end.
