SDUR830

Single Diodes Overview

The SDUR830 is a standard single diode manufactured by SMC Diode Solutions, designed for surface mount applications in the DPAK (TO-252) package. It features a maximum DC reverse voltage of 300 V and an average forward rectified current of 8 A. The device exhibits a fast recovery speed with a reverse recovery time of 45 ns. Forward voltage is specified at 1.3 V when conducting 8 A, while reverse leakage current remains at 10 µA under full reverse voltage conditions. Operating junction temperature ranges from -55°C to 150°C.

Single Diodes Feature Summary

• Fast recovery characteristics suitable for high-frequency switching environments
• Robust thermal performance with a wide operating junction temperature range
• Low forward voltage drop for improved efficiency
• Compact surface-mount packaging for automated assembly

Single Diodes Applications

• Antiparallel diode for high frequency switching devices
• Anti-saturation diode circuits
• Snubber diode applications
• Free wheeling diode in inductive load protection

Single Diodes Procurement Notes

Verify the specific package variant required, as the model designation may correspond to different physical packages such as TO-220AC or DPAK depending on the suffix. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides official datasheets matching the exact part number to avoid discrepancies in electrical parameters or pin configurations.

Single Diodes Selection Notes

Select this component for circuits requiring fast recovery times around 45 ns and moderate current handling up to 8 A. The 300 V reverse voltage rating makes it suitable for low-voltage AC/DC conversion stages. Consider the thermal resistance of the chosen package type for heat dissipation requirements in dense PCB layouts.

Single Diodes Part Context

This component belongs to the SDUR series of fast recovery diodes from SMC Diode Solutions. The series includes variants with different voltage and current ratings, sharing similar technological foundations. These diodes are engineered for general-purpose rectification where speed is critical, distinguishing them from standard slow-recovery rectifiers used in power supplies.

Single Diodes Replacement Considerations

Cross-reference with other 300V 8A fast recovery diodes in the same package family. Verify that substitute parts meet the 45 ns reverse recovery time requirement and match the forward voltage specifications to ensure circuit compatibility.
