SDUR1040CT

Diode Arrays Overview

The SDUR1040CT is a general-purpose fast recovery rectifier diode array manufactured by SMC Diode Solutions. It features a common cathode configuration with two internal diodes housed in a D2PAK (TO-263-3) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1 A per diode. Key electrical characteristics include a maximum reverse recovery time of 50 ns and a typical forward voltage drop of 1.35 V at 5 A. The component operates within a junction temperature range of -55°C to 150°C.

Diode Arrays Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• Common cathode dual-diode configuration for efficient circuit design
• Robust thermal management via the exposed pad in the D2PAK package

Diode Arrays Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in motor control circuits
• Snubber circuits in power supplies

Diode Arrays Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout and packaging variations. Ensure the ordering part number matches the required tape-and-reel or cut-tape format. Confirm RoHS compliance status and moisture sensitivity level requirements prior to final procurement decisions.

Diode Arrays Selection Notes

Select this component when a compact, surface-mount solution is required for low-current, high-speed rectification. Compare the 400 V rating against circuit voltage spikes and ensure the 1 A current limit meets load requirements. Evaluate the thermal resistance of the PCB layout to maintain safe operating temperatures under continuous load conditions.

Diode Arrays Part Context

This part belongs to the SDUR series of fast recovery diode arrays from SMC Diode Solutions. It shares the same physical footprint and basic topology as variants like the SDUR1060CT and SDUR1030CT, differing primarily in reverse voltage ratings. The series targets space-constrained designs requiring reliable fast-switching capabilities.

Diode Arrays Replacement Considerations

SDUR1060CT offers identical packaging and configuration with a higher 600 V rating. SDUR1030CT provides the same form factor but with a lower 300 V rating. Verify that any substitute maintains compatible reverse recovery times and forward voltage characteristics.
