Yes, but remember it’s just the voltage across the diode which, for silicon diodes, will be about 0.

FR107 – FR107 1000V 1A Fast Recovery Diode
Yes, in this case all power dissipated will be in the form of heat. According to this chart of a diode’s power dissipation over temperature, the power dissipation would decrease as temperature goes up.
It shows permissible power dissipation as a function of ambient temperature. The latter parameter covers the thermal resistance of the chip to case, case to heatsink if provided and heatsink to air or coolant.
The graph is not showing how much power the diode will dissipate as a function of temperature. If it’s hot all around, less power will get something to a particular temperature than when it’s cold all around. Watts dissipated at the diode are the problem.

Email Required, but never shown. This chart is means to aid in thermal design, to know where to place or not to place the diode on the board, and to figure out what size of heat sink you need.
Remember that temperature of the device rises until the power lost to cooling equals the electrical power input.

Watts that “go through” the diode won’t affect it as they’ll get to the load. In other cases it might not as explained above. Understanding power dissipation of a diode in a datasheet chart Ask Question. Post as a guest Name. You wrote “the power to be dissipated must decrease to stay in the safe operating area Dagasheet. But wouldn’t it be the exact opposite and even more power be dissipated as heat, when the temperature goes up?
You appear to have written two sentences but separated them by a comma so it’s not clear what you are saying. Autistic 7, 2 15 No, it shows how much power the diode by itself can dissipate at different temperatures. Probably not the best way.
