Overview
The 127SPC020A is a power surface mount Schottky rectifier manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage (Vr) of 20 V and an average rectified current (Io) of 120 A. The forward voltage drop (Vf) is specified at a maximum of 480 mV when tested at 120 A. The component utilizes Schottky technology to ensure efficient rectification with low power loss. It is housed in the SPD-3A package, designed for robust surface mount applications requiring high current handling capabilities.
Feature Summary
- Schottky barrier technology for low forward voltage drop
- High current capacity of 120 A average rectified current
- Surface mount packaging for automated assembly
Applications
- DC-DC converters
- Power supply units
- Solar panel rectification
Procurement Notes
Verify the specific datasheet version from SMC Diode Solutions to confirm RoHS compliance status, as sources indicate no RoHS information is available. Ensure the SPD-3A package dimensions match your PCB footprint requirements. Confirm that the 20 V reverse voltage rating provides sufficient margin for your circuit's peak inverse voltage conditions. Check for any specific storage or handling guidelines provided in the official documentation.
Selection Notes
Select this component when a low forward voltage drop is critical for efficiency in high-current applications. The 20 V rating suits low-voltage DC systems. Consider the thermal management requirements associated with the SPD-3A package under full 120 A load. Compare against other Schottky diodes if higher voltage ratings are needed, but note that this part is optimized for the 20 V range.
Part Context
This device belongs to the series of power surface mount Schottky rectifiers produced by SMC Diode Solutions. These components are designed for general-purpose rectification in power electronics. The SPD-3A package is a standard form factor for high-current surface mount diodes, facilitating integration into compact power designs.
Replacement Considerations
Consult official substitution lists from SMC Diode Solutions for verified equivalents. Ensure any replacement maintains the 120 A current rating and 20 V reverse voltage specification. Verify that the alternative component uses the same SPD-3A package or has a compatible pinout and thermal profile.
