Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the part number with the latest revision of the technical data sheet to confirm electrical parameters match your design constraints before finalizing procurement.

Diode Arrays Selection Notes

Select this component for applications requiring fast recovery characteristics and high current handling in a dual common cathode configuration. The 400 V rating suits medium-voltage AC/DC conversion systems. Evaluate thermal management needs based on the 2 x 10 A continuous current rating and the specific mounting conditions of the TO-247AD package.

Diode Arrays Part Context

This device belongs to the SDUR series of ultrafast plastic rectifiers from SMC Diode Solutions. It is designed as a dual common cathode unit, providing two independent rectifying paths within a single package. The series emphasizes high-speed switching performance suitable for modern high-frequency power electronics applications.

Diode Arrays Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the 400 V reverse voltage, 20 A total current capacity, and similar reverse recovery time specifications.
