Hi Guys,
I unable to calculate the temperature rise (Temperature rise = Power dissipation * Junction to Ambient Thermal Resistance) of a schottky diode as the Junction to Ambient Thermal Resistance is not specified in the datasheet.
I have read some article online that the Junction to Ambient Thermal Resistance is able to be calculated by << (Junction Temperature - Ambient Temperature) / Maximum power dissipation>>.
Question:
3. I have heard from somebody claims that if the application of the schottky diode is without heatsink, the junction to case thermal resistance in the datasheet is equal to its junction to ambient thermal resistance. Is it true?
Thanks and please guide.

Question:
- The mentioned junction temperature for determination of junction to ambient thermal resistance is referring to (a) or (b)? From my understanding, it should be (b).
- (a) The maximum junction temperature of the schottky diode OR
- (b) The junction temperature when the schottky diode disspiating maximum power.
