SDUR1020CT

Diode Arrays Overview

The SDUR1020CT is a general-purpose fast recovery rectifier diode array manufactured by SMC Diode Solutions. It features a common cathode configuration housed in a surface-mount DPAK (TO-252-3) package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 5 A. Key electrical parameters include a maximum reverse leakage current of 10 µA at 200 V, a forward voltage drop of 975 mV at 5 A, and a typical reverse recovery time of 35 ns. It operates within a junction temperature range of -55°C to 150°C.

Diode Arrays Feature Summary

• Fast recovery performance with a typical reverse recovery time of 35 ns for efficient switching applications
• Common cathode dual diode configuration simplifies circuit design for bridge or freewheeling topologies
• Robust thermal management capabilities via the exposed tab in the DPAK surface-mount package

Diode Arrays Applications

• High-frequency DC/DC converter output rectification
• Free-wheeling diodes in inductive load switching circuits
• General-purpose rectification in low-to-medium power power supplies

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly standards. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current production status before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a fast-switching characteristic is required alongside moderate current handling in a compact surface-mount form factor. The 200 V rating suits low-voltage DC bus applications. Compare the 35 ns reverse recovery time against slower standard recovery alternatives to ensure compatibility with the target switching frequency and electromagnetic interference constraints.

Diode Arrays Part Context

This part belongs to the SDUR series of fast recovery rectifiers from SMC Diode Solutions. It shares the SDURD1020 basic product designation but utilizes the CT suffix to denote specific packaging variations such as cut tape or reel configurations. It serves as a discrete alternative to integrated bridge rectifiers in single-phase applications requiring individual diode control.

Diode Arrays Replacement Considerations

Direct substitutes include other 200 V, 5 A fast recovery diodes in DPAK packages from different manufacturers. Verify that any replacement maintains equivalent reverse recovery time and forward voltage characteristics to preserve circuit efficiency.
