MUR405

Single Diodes Overview

The MUR405 is a silicon rectifier diode manufactured by onsemi, belonging to the MUR series of ultra-fast recovery rectifiers. It features a single-phase, single-element configuration housed in a DO-201AD plastic package. The device is rated for a maximum repetitive reverse voltage of 50V and supports a continuous forward current of 4A. Key electrical characteristics include a low forward voltage drop and ultra-fast switching speed designed for high-efficiency applications. The component is RoHS compliant and lead-free.

Single Diodes Feature Summary

• Ultra-fast switching speed optimized for high efficiency
• Low leakage current and low forward voltage drop
• High surge current capability

Single Diodes Applications

• High frequency rectification circuits
• Free-wheeling diodes
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix (e.g., GP) against the datasheet to confirm compliance details such as halogen-free status or lead finish. Confirm package type matches DO-201AD requirements. Check for obsolescence notices as product lifecycles may vary. Ensure thermal management aligns with the specified junction temperature range.

Single Diodes Selection Notes

Select this component when an ultra-fast recovery time is required for efficient power conversion. The 4A rating suits moderate current applications. Verify that the 50V reverse voltage rating exceeds the peak inverse voltage in the target circuit. Consider the DO-201AD through-hole package for mechanical mounting constraints.

Single Diodes Part Context

This part belongs to the MUR series of ultra-fast recovery rectifiers from onsemi. These devices are engineered to replace standard fast recovery diodes where reduced reverse recovery time improves system performance. The series covers various voltage and current ratings within the same package family.

Single Diodes Replacement Considerations

Direct substitutes include other 4A, 50V ultra-fast recovery diodes in DO-201AD packages. Verify matching reverse recovery time and forward voltage specifications. Cross-reference with Micro Commercial Components MUR405GP for equivalent performance parameters.
