Single Diodes Procurement Notes

Verify the specific suffix code on the component marking against official manufacturer documentation to confirm exact electrical tolerances and packaging type. Ensure the procurement source provides valid RoHS compliance certificates and datasheet references matching the SMC Diode Solutions SDURB2020 specification sheet. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Single Diodes Selection Notes

Select this component when circuit designs require low reverse recovery charge and high surge current handling in a surface-mount D2PAK footprint. It is suitable for replacing standard recovery diodes where switching losses must be minimized. Confirm that the 200 V reverse voltage rating exceeds the peak inverse voltage present in the target application circuit under all operating conditions.

Single Diodes Part Context

This device belongs to the SDURB series of ultrafast recovery diodes from SMC Diode Solutions. The series utilizes flip-chip technology to achieve superior thermal dissipation and electrical performance compared to conventional wire-bonded packages. The SDURB2020 specifically targets general-purpose high-efficiency rectification needs in compact power supply designs.

Single Diodes Replacement Considerations

Compatible substitutes include the SDURB2020CT-A and SDURB2040 from the same manufacturer family. Verify pinout compatibility and ensure the replacement part meets or exceeds the 200 V reverse voltage and 20 A current requirements of the original design.
