How do you plan to get the junction temperature?Many thanks for those replies ... Indeed, I know how to get a junction temperature but I want to size when only to know how could I get the max temperature the device could sustain befor thermal runaway ... I want to reproduce the max tj given in the datasheet
Actually I want to know if the degradation of a device could impact its maximum temperature it could sustainThe manufacturer states the maximum operating junction temperature of the device. The junction temperature can be determined from the device power dissipation, the ambient temperature, and the device thermal resistance from junction to air, so I don't see the purpose is of what you are trying to do.
You seem to be trying to reinvent the wheel.
What type of degradation? There are many types.Actually I want to know if the degradation of a device could impact its maximum temperature it could sustain
The degradation is a hci one and the metrics would be vth, ion, gmWhat type of degradation? There are many types.
In general, I would expect most forms of degradation to impact the maximum junction temperature, but again it matters what you are talking about when you talk about the maximum temperature it could sustain. What are you metrics?
Yes, it could.Actually I want to know if the degradation of a device could impact its maximum temperature it could sustain
Is this just for you own edification?I need to check it and demonstrate it
