Response By EW AI
✅ Component type is a diode, suitable for rectifier/flyback use.
✅ Diode type requirement is satisfied: DigiKey lists Technology as Standard, which matches a general purpose rectifier.
✅ Average rectified current is 1A, meeting the required ≥1A and comfortably above the 80 mA relay coil current.
✅ Repetitive reverse voltage is 600V, exceeding the required ≥40V.
✅ Package is SMA (DO-214AC, SMA), matching the required SMA package.
✅ Mounting type is Surface Mount, matching the requirement.
✅ Operating temperature range is -65°C to 150°C junction, which is wider than the required -40°C to +125°C or wider.
✅ RoHS compliance is satisfied: ROHS3 Compliant.
All listed requirements are satisfied, so this component is approved for relay flyback protection in this application.
