SS220B-HF

Single Diodes Overview

The SS220B-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 2 A. The device utilizes a DO-214AA (SMB) package for efficient thermal management. Key electrical characteristics include a low forward voltage drop of 950 mV at the rated current, ensuring high energy efficiency. It is designed for general-purpose rectification applications requiring fast switching capabilities.

Single Diodes Feature Summary

• Schottky barrier construction for minimal power loss
• Fast recovery time suitable for high-frequency circuits
• Lead-free finish compliant with RoHS standards

Single Diodes Applications

• General purpose rectification in consumer electronics
• Power supply output stages
• DC-DC converter freewheeling diodes

Single Diodes Procurement Notes

Verify the specific datasheet revision to confirm pinout orientation and marking codes. Ensure the DO-214AA package dimensions match your PCB footprint requirements. Confirm that the 2A current rating aligns with your circuit's thermal design constraints under expected operating conditions.

Single Diodes Selection Notes

Select this component when a 200V blocking voltage and 2A continuous current are required in a compact SMB package. Consider its low forward voltage for efficiency-critical designs. Compare against standard silicon rectifiers if switching speed is a primary design constraint.

Single Diodes Part Context

This part belongs to Comchip Technology's line of surface-mount Schottky rectifiers. It is distinct from through-hole variants and higher-current SMB series devices. The 'HF' suffix indicates halogen-free manufacturing processes, aligning with environmental compliance standards for modern electronic assemblies.

Single Diodes Replacement Considerations

Direct substitutes must maintain the 200V reverse voltage and 2A current ratings in a DO-214AA package. Verify equivalent forward voltage and reverse leakage specifications to ensure circuit performance parity.
