Response By EW AI

✅ Diode type: Schottky, which matches the reverse polarity protection requirement.
✅ Average rectified current: 2A, which exceeds the required ≥1A and is suitable for a 500 mA load with margin.
✅ Repetitive reverse voltage: 40V, which exceeds the required ≥30V for a 12V DC input.
✅ Forward voltage: 490 mV max @ 2A, which satisfies the required ≤0.5V. This supports low loss in series input protection.
✅ Package: DO-214AC (SMA), which matches the required SMA package.
✅ Mounting type: Surface Mount, which matches the requirement.
✅ Operating temperature range: -65°C to 150°C junction, which is wider than the required -40°C to +125°C or wider.
✅ RoHS compliance: ROHS3 Compliant, which satisfies the requirement.

All listed requirements are satisfied. This component is approved for the stated reverse polarity protection application.
