what precautions to choose Schottky diodes

Schottky diodes are very common in electronic circuits, what precautions should be taken in their application?

1. It should be less than the forward rated current IF of the Schottky diode.

2. The peak operating voltage of the application circuit should be less than the highest reverse breakdown voltage VRRM of the Schottky diode.

3. The actual operating temperature rise of the Schottky diode in the application circuit should be less than the highest junction temperature Tjmax of the Schottky diode.

For harsh environments, in order to ensure reliability, Schottky diodes should be derated for use.

5. For application circuits with high surge voltage or surge current, suppression and absorption circuits should be added.

6. The replacement of Schottky diodes  should choose the original model as much as possible, as different models of Schottky diodes have different forward voltage drop VF, reverse breakdown voltage VR, and reverse leakage current IR.
