If it’s hot all around, less power will get something to a particular temperature than when it’s cold all around. Probably not the best way. You appear to have written two sentences but separated them by a comma so it’s not clear what you are saying.
FR107 – FR107 1000V 1A Fast Recovery Diode
Watts dissipated at the diode are the problem. Only if that is absorbed by something will it be converted to and that at the point of absorption not at the source. Sign up or log in Sign up using Google. Olin Lathrop k 30 The latter parameter covers the thermal resistance rr107 the chip to case, case to heatsink if provided and heatsink to air or coolant.
Home Questions Tags Users Unanswered. Yes, but remember it’s just the voltage across the diode which, for silicon diodes, will be about 0. Email Required, but never shown. But wouldn’t it be the exact opposite and even more power be dissipated as heat, when the temperature goes up?
Post as a guest Name. Remember that temperature of the device rises until the power lost to cooling equals the electrical power input. You wrote “the power to be dissipated must decrease to stay in the safe operating area SOA. The graph is not showing how much power the diode will dissipate as a function of temperature.
Autistic 7, 2 15 Yes, in this case all power dissipated will be in the form of heat. No, it shows how much power the diode by itself can dissipate at different temperatures.
FR Datasheet(PDF) – Diodes Incorporated
According to this chart of a diode’s power dissipation over temperature, the power dissipation would decrease as temperature goes up. This chart is means to aid in thermal design, to fatasheet where to place or not to place the diode on the board, and to figure out what size of heat sink you need.
In other cases it might not as explained above.
It shows permissible power dissipation as a function of ambient temperature. I didn’t use the expression, “The power to be dissipated” so I don’t understand why you are quoting it back to me.
