Procurement Notes

Verify the specific suffix (e.g., -HF) to confirm RoHS compliance and halogen-free status, as standard part numbers may vary in environmental certifications. Confirm the package type matches the PCB footprint requirements during procurement. Ensure the ordering quantity aligns with tape-and-reel specifications if automated assembly is planned. Cross-reference the manufacturer's latest datasheet to validate active status and availability before finalizing orders.

Selection Notes

Select this component for applications requiring low forward voltage and fast recovery times in space-constrained environments. The 20 V rating suits low-voltage DC systems. Evaluate thermal management needs based on the 100 mA continuous current limit. Compare capacitance values against high-speed signal integrity requirements. Ensure the surface-mount package compatibility with existing manufacturing equipment.

Part Context

This component belongs to the CDBFR series of Schottky diodes from Comchip Technology. The series focuses on small-signal rectification and switching applications. These devices are designed for surface-mount technology, offering reliability in consumer electronics and industrial control systems. The series emphasizes low profile and high performance within limited board space constraints.

Replacement Considerations

Check for direct substitutes with identical 20 V reverse voltage and 100 mA forward current ratings. Verify package dimensions and pinout compatibility to ensure seamless integration without PCB redesign. Confirm electrical characteristics such as forward voltage and reverse leakage match or exceed original specifications.
