NXP FlatPower MEGA Schottky rectifier - Thermal selection criteria

from the data sheet:

(12)

(13)

So thermal and electrical parameters are essential factors for the selection of the right

PMEG Schottky barrier rectifier under considerations.

Changing the package (bigger package size, bigger silicon die, better thermal

performance) fulfill easier the requirements than increasing the cooling pad area.

3.3 Conclusion

The characteristics given in the data sheet, help choosing the right PMEG Schottky barrier

rectifier. The most critical question in hardware design is the maximum allowable

Data sheet parameters are a good instrument to compare different products under

standard conditions.
