Engineering review checklist
- Check voltage, continuous and pulsed current, safe operating area and junction-temperature limits.
- Evaluate conduction and switching losses using the specified drive conditions rather than headline ratings.
- Confirm pinout, package thermal path, gate or base protection and transient derating in the final circuit.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
