MURD330T4G

Single Diodes Overview

The MURD330T4G is a single ultrafast recovery power rectifier manufactured by onsemi. It features a maximum average forward rectified current of 3A and a repetitive peak reverse voltage of 300V. The device utilizes a DPAK surface-mount package, specifically the SOT-57 variant. Key electrical characteristics include a typical reverse recovery time of 35ns and a maximum non-repetitive peak forward surge current of 75A. The component is designed for high-speed switching applications requiring low leakage current.

Single Diodes Feature Summary

• Ultrafast recovery performance with minimal reverse recovery charge
• Low leakage current capability for efficient operation
• Surface-mount construction for automated assembly

Single Diodes Applications

• High-frequency DC-to-DC converters
• Free-wheeling diode circuits in power supplies
• Isolated output rectification in flyback topologies

Single Diodes Procurement Notes

Verify the specific datasheet revision to confirm pinout compatibility and thermal resistance values. Ensure the ordering suffix matches the required tape and reel quantity specifications. Confirm that the application environment remains within the specified junction temperature limits for reliable long-term operation.

Single Diodes Selection Notes

Select this component when a 3A current rating and 300V blocking voltage are required in a compact surface-mount form factor. Consider the 35ns reverse recovery time for high-frequency efficiency requirements. Evaluate thermal management needs based on the DPAK package's heat dissipation capabilities under expected load conditions.

Single Diodes Part Context

This part belongs to the MURD series of ultrafast recovery rectifiers from onsemi. It is functionally similar to other devices in the family but distinguished by its specific 300V voltage rating and 3A current capacity. The DPAK package provides a balance between current handling and board space efficiency compared to larger through-hole alternatives.

Single Diodes Replacement Considerations

The MURD320T4G serves as a verified substitute within the same series, offering identical 3A current ratings but with a reduced 200V reverse voltage rating. Verify that the lower voltage specification meets the circuit's peak inverse voltage requirements before substitution.
