Example 2: High-temperature application
Using the same rules, it is possible to address applications that run at high ambient
temperatures with a low dissipation, as long as junction temperature T
specified range.
Assuming the following application conditions:
Thus: P
Using the values obtained in
This is above the range of the suffix 6 version parts (–40 < T
In this case, parts must be ordered at least with the temperature range suffix 7 (see
Section 8: Part
use suffix 6 parts.
Refer to figure 38 to select the required temperature range (suffix 6 or 7) according to your
ambient temperature or power requirements.
