What are the precautions for Schottky diode application?
Schottky diodes are very common in electronic circuits. What should be paid attention to in application?
1. It shall be less than the forward rated current IF of Schottky diode.
2. The peak working voltage of the application circuit shall be less than the maximum reverse breakdown voltage VRRM of the Schottky diode.
3. The actual working temperature rise of the Schottky diode in the application circuit shall be less than the maximum junction temperature Tjmax of the Schottky diode.
4. For harsh environments, Schottky diodes should be derated to ensure reliability.
5. For application circuits with large surge voltage or surge current, suppression and absorption circuits should be added.
6. The schottky diode shall be replaced by the original model as far as possible, because the forward voltage drop VF, reverse breakdown voltage VR and reverse leakage current IR of schottky diodes of different models are different.
