case temperature指的是封装外壳表面的温度;ambient temperature 指的是距离封装外壳表面1-2cm处的温度;junction temperature指的是半导体裸片温度;
The datasheet specifies "operating temperature" range "-40°C to +85°C". The parameter name is "Ta" indicating that it refers to ambient temperature, right? The abs max rating for storage is +150°C. The thermal parameters all refers to junction temperature. What is the ...

In general ESD protection devices are assuming negligible current draw due to leakage and therefore Tj = Ta 6 年多前 Cameron Phillips6 年多前 TI__Genius12410points Hello, The junction temperature is not the ambient temperature during an ESD event. However because the ESD pulse is so short...
Below is an example of the correlation between current consumption and the junction temperature when Rth (j-a) is 250 deg./W , the ambient temperature is 25 deg. The junction temperature rises in proportion to the current consumption. The proportionality constant for this is Rth(j-a). Since...

By keeping the junction temperature low, the long-term reliability of the device improves. Use Equation 1 to estimate the junction temperature. where: TJ is the junction temperature (°C). TA is the ambient temperature (°C). θJA is the junction to ambient thermal resistance (°C/W). ...
TAis the ambient temperature (°C). θJAis the junction to ambient thermal resistance (°C/W). PDISSis the total device power dissipation (W). The maximum ambient operating conditions appear on all Analog Devices data sheets. The junction temperature, thermal resistance, and power dissipation ar...
