Watts that “go through” the diode won’t affect it as they’ll get to the load. Sign up using Facebook. If it’s hot all around, less power will get something to a particular temperature than when it’s cold all around.

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.

Yes, but remember it’s just the voltage across the diode which, for silicon diodes, will be about 0. I didn’t use the expression, “The power to be dissipated” so I don’t understand why you are quoting it back to me.

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. 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. Probably not the best way. You wrote “the power to be dissipated must decrease to stay in the safe operating area SOA.

1.0A Fast Recovery Diode FR101-FR107

The graph is fr017 showing how much power the diode will dissipate as a function of temperature. Watts dissipated at the diode are the problem. Olin Lathrop k 30 Remember that temperature of the device rises until the power lost to cooling equals the electrical power input.

But wouldn’t it be the exact opposite and even more power be dissipated as heat, when the temperature goes up?

No, diodw shows how much power the diode by itself can dissipate at different temperatures. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
