Procurement Notes
Verify the specific ordering suffix when sourcing components. Manufacturer designations often include suffixes such as -HF to indicate lead-free compliance or RoHS status. Confirm that the received part matches the exact alphanumeric code required for the circuit design to ensure correct voltage and current ratings are met.
Selection Notes
Select this component for applications requiring a compact surface-mount Schottky rectifier with moderate current handling. The SOD-123F package offers a smaller footprint compared to standard packages. Ensure the operating environment stays within the specified temperature range and that the reverse voltage requirements do not exceed the 20 V rating.
Part Context
This component belongs to the Comchip Technology Schottky Diode product line. The manufacturer specializes in various semiconductor devices including rectifiers, Zener diodes, and TVS protectors. The company holds ISO certifications and designs products suitable for industrial and consumer electronics markets.
Replacement Considerations
Compatible substitutes include other 20V 500mA Schottky diodes in the SOD-123F package. Verify pinout compatibility and thermal resistance specifications before substitution.
