Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
