SDURB3030CT

Diode Arrays Overview

The SDURB3030CT is a general-purpose ultra-fast recovery diode array manufactured by SMC Diode Solutions. It features a common cathode configuration with two independent diodes housed in a D2PAK (TO-263-3) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 300 V and an average forward rectified current of 15 A per diode. Key electrical characteristics include a typical reverse recovery time of 45 ns, a maximum reverse leakage current of 30 µA at 300 V, and a forward voltage drop of 1.55 V at 15 A. The junction operating temperature range extends from -55°C to 150°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape-and-reel or cut-tape, as these affect handling and assembly processes. Confirm that the component complies with RoHS3 directives and REACH regulations for the target market. Ensure the selected variant aligns with the intended thermal management strategy given the D2PAK package's heat dissipation requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a common cathode arrangement with high current ratings and fast switching speeds. The 300 V reverse voltage rating suits medium-voltage power stages, while the 15 A current capacity supports substantial load demands. Consider the thermal resistance of the D2PAK package for heatsinking requirements. Compare the reverse recovery time against system switching frequencies to minimize switching losses. Evaluate the forward voltage drop impact on overall efficiency at the expected operating current levels.
