Procurement Notes
Verify the specific ordering suffix, such as -HF, against the manufacturer's datasheet to ensure compliance with environmental standards like RoHS. Confirm the package designation matches the required footprint, as variations exist within the series. Cross-reference the part number with official distributor catalogs to validate current availability and lead times before finalizing procurement plans.
Selection Notes
Select this component for applications requiring compact surface-mount solutions with low forward voltage characteristics. Ensure the circuit operating voltage remains below the 30 V reverse voltage limit. Consider the 200 mA current rating when designing power stages. Verify thermal management requirements align with the package's dissipation capabilities for continuous operation.
Part Context
This component belongs to the CDBQR series of small signal Schottky diodes from Comchip Technology. The series is designed for low-profile surface mount applications, offering a thinner profile compared to standard packages. It serves as a compact alternative for rectification and switching tasks where space constraints are critical.
Replacement Considerations
Direct substitutes may include other 0402/SOD-923F packaged Schottky diodes with matching 30 V and 200 mA ratings. Verify pinout compatibility and forward voltage specifications before substitution. Consult manufacturer cross-reference lists for validated equivalent parts.
