Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to ensure correct voltage and current ratings. Confirm RoHS compliance status and packaging details such as reel or cut tape options directly with the supplier or authorized distributor before ordering. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component for designs requiring a 2.0 A continuous forward current and 20 V reverse voltage blocking capability in an SMA package. Consider the thermal resistance and derating curves when determining heat dissipation requirements. Verify that the low forward voltage characteristic aligns with the system's power loss constraints and efficiency targets.
Part Context
This component belongs to the CDBA220L-G through CDBA240LL-G series of Low VF SMD Schottky Barrier Rectifiers from Comchip Technology. The series offers various reverse voltage ratings ranging from 20 V to 40 V while maintaining a consistent 2.0 A forward current rating. These devices are designed for high-efficiency rectification in compact surface-mount layouts.
Replacement Considerations
Cross-reference with other Schottky rectifiers in the DO-214AC package having equivalent 2.0 A and 20 V ratings. Verify forward voltage drop and reverse leakage current specifications match application requirements. Ensure thermal resistance and physical dimensions are compatible with the existing PCB footprint.
