5.3.1.2
To estimate the internal junction temperature, the
calculated temperature rise is added to the ambient or
offset temperature. For this example, the worst-case
junction temperature is estimated below:
As you can see from the result, this application will be
operating within the maximum operating junction
temperature of 125°C.
5.3.1.3
From this table you can see the difference in maximum
allowable power dissipation between the TO-220-5
package and the DDPAK-5 package.
