Diode 45 V 3.8A Surface Mount DO-214AA (SMB)
Response By EW AI
✅ Diode type: Schottky, which matches the required catch diode type for a buck converter.
✅ Average rectified current: 3.8A, which exceeds the minimum requirement of 3A.
✅ Repetitive reverse voltage: 45V, which exceeds the minimum requirement of 30V and provides adequate margin for a 12V input buck converter.
✅ Forward voltage: 430mV max at 3.5A, which is below the required maximum of 0.55V and supports better efficiency.
✅ Package: DO-214AA (SMB), which matches the required SMB package.
✅ Mounting type: Surface Mount, which matches the requirement.
✅ Operating temperature range: -40°C to +150°C junction, which is wider than the required -40°C to +125°C.
✅ RoHS compliance: ROHS3 Compliant, which satisfies the requirement.
All listed requirements are satisfied. This component is suitable for Schottky catch diode use in the specified buck converter and is approved.
