SDUR1660CT

Diode Arrays Overview

SDUR1660CT is a dual common cathode ultra-fast recovery diode array manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 8 A per leg. The device exhibits a fast reverse recovery time of 35 ns with low stored charge, ensuring efficient high-frequency operation. It is housed in a TO-220AB package with an isolated tab for thermal management. The component operates within a junction temperature range of -55°C to 150°C and complies with RoHS3 standards.

Diode Arrays Feature Summary

• Ultra-fast recovery characteristics with 35 ns reverse recovery time
• Dual common cathode configuration for bridge or push-pull applications
• Low forward voltage drop for improved efficiency
• Isolated tab design for effective heat dissipation

Diode Arrays Applications

• High frequency switching power supplies
• Free wheeling diodes in DC-DC converters
• Snubber circuits for transient suppression
• Anti-parallel protection for inductive loads

Diode Arrays Procurement Notes

Verify the specific suffix 'CT' corresponds to the tube packaging format when ordering, as standard SDUR1660 may differ. Confirm that the TO-220AB package dimensions match the target PCB footprint. Ensure the 600V rating provides sufficient margin for the circuit's peak inverse voltage requirements. Check for RoHS3 compliance if environmental regulations apply to the final assembly.

Diode Arrays Selection Notes

Select this component for applications requiring rapid switching speeds and high current handling in a through-hole configuration. The common cathode arrangement simplifies circuit topology compared to discrete pairs. Consider the thermal resistance of the TO-220AB package relative to the expected power dissipation. Compare against standard recovery diodes if cost is a primary constraint, acknowledging potential performance trade-offs in switching losses.

Diode Arrays Part Context

The SDUR1660CT belongs to the SDUR series of ultra-fast recovery diodes from SMC Diode Solutions. This series is designed for demanding power electronics applications where speed and reliability are critical. The CT designation typically indicates a tube package variant, distinguishing it from tape-and-reel options like SDUR1660TR. It serves as a robust solution for medium-to-high power conversion systems.

Diode Arrays Replacement Considerations

SDUR1660 is a compatible alternative part number representing the same electrical specifications but potentially different packaging. Verify pinout compatibility and thermal characteristics before substitution. Other manufacturers offer equivalent 600V 8A dual common cathode ultra-fast diodes, but direct parameter matching is required.
