According to this chart of a diode’s power dissipation over temperature, the power dissipation would decrease as temperature goes up. But wouldn’t it be the exact opposite and even more power be dissipated as heat, when the temperature goes up? The latter parameter covers the thermal resistance of the chip to case, case to heatsink frr107 provided and heatsink to air or coolant. Remember that temperature of the device rises until the power lost to cooling equals the electrical power input.
Yes, but remember it’s just the voltage across the diode which, for silicon diodes, will be about doode.

Probably not the best way. Watts that “go through” the diode won’t affect it as they’ll get to the load. Watts dissipated at the diode are the problem.

Autistic 7, 2 15 I didn’t use the expression, “The power to be dissipated” so I don’t understand why you are quoting it back to me. You appear to have written two sentences but separated them by a comma so it’s not clear what you are saying.
Diose example, some power could be in the form of electromagnetic radiation such as radio waves or light.
Only if that is absorbed by something will it be converted to and that at the point of absorption not at the source. You wrote “the power to be dissipated must decrease to stay in the safe operating datasyeet SOA.
Yes, in this case all power dissipated will be in the form of heat.

Datasheft other cases it might not as explained above. The graph is not showing how much power the diode will dissipate as a function of temperature.
Olin Lathrop k 30 No, it shows how much power the diode by itself can dissipate at different temperatures. This chart is means to aid in thermal design, to know ffr107 to place or not to place the diode on the board, and to figure out what size of heat sink you need.
