The maximum rated junction temperature, TJM, and the
thermal resistance of the heat dissipating path determines
the maximum allowable device power dissipation, P
application. Therefore the application’s ambient
temperature, T
must be reviewed to ensure that T

In using surface mount devices such as the TO-263
package, the environment in which it is applied will have a
significant influence on the part’s current and maximum
power d issipati on rating s. Precise d etermin ation of P
comple x and influenced by many factors:
DM
is
1. Mou nting pad area ont o which the device is attached and
whet her the re is copp er on one s ide or both side s of the
board.
2. The number of copper layers and the thickness of the
board.
3. The use of external heat sinks.
4. The use of thermal vias.
5. Air flow and board orientation.
6. For no n steady state applic ations, th e pulse widt h, the
duty cycle and the transient thermal response of the part,
the boa rd and the environment they are in.
Fairchild provides thermal information to assist the
designer’s preliminary application evaluation. Figure 21
