✅ Diode type: Schottky, which matches the required catch diode type for a buck converter.
✅ Average rectified current: 3A, meeting the requirement of ≥3A.
✅ Repetitive reverse voltage: 40V, exceeding the required ≥30V and providing suitable margin for a 12V input buck converter.
✅ Forward voltage: 550mV @ 3A, meeting the requirement of ≤0.55V.
✅ Package: SMB (DO-214AA, SMB), matching the required SMB package.
✅ Mounting type: Surface Mount, matching 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, satisfying the requirement.
All listed requirements are satisfied. This component is suitable for Schottky catch diode operation in the 12V to 5V buck converter and is approved.
