Differences & datasheets
  • Threshold measurement conditions differ. Diodes' checked table does not guarantee on-resistance at 4.5 V.
  • Do not infer logic-level suitability from threshold voltage. Use a guaranteed on-resistance at the actual gate drive.
  • Respect the candidate's lower limits where applicable and verify SOA, body diode, switching loss, and PCB thermal design.
  • Gate charge, avalanche rating, switching timing, complete temperature curves, and assembly tolerances are not fully matched.
