Differences & datasheets
  • Continuous, average, and surge current specifications use different limits and mounting conditions.
  • Verify reverse-voltage margin, forward drop, leakage, surge current, and temperature for the actual circuit.
  • Check the complete package drawing and land pattern or lead spacing.
  • Recovery behavior over temperature, parasitics, thermal layout, and qualification equivalence are not fully matched.
