MURS240-M3/52T

Single Diodes Overview

The MURS240-M3/52T is a surface-mount ultrafast plastic rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated pellet chip junction and operates in the SMB (DO-214AA) package. The device supports a maximum repetitive peak reverse voltage of 400 V and a maximum average forward rectified current of 2.0 A at a lead temperature of 125 °C. Key electrical characteristics include a maximum instantaneous forward voltage of 1.45 V at 25 °C, a maximum reverse recovery time of 50 ns, and a peak forward surge current capability of 35 A. The component is rated for an operating junction and storage temperature range from -65 °C to +175 °C.

Single Diodes Feature Summary

• Ultrafast reverse recovery time with low switching losses for high efficiency
• Glass passivated pellet chip junction for enhanced reliability
• High forward surge current capability suitable for demanding loads
• Halogen-free, RoHS-compliant construction meeting JESD 201 class 2 whisker test

Single Diodes Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in consumer electronics
• Inverter circuits for computer and telecommunication equipment

Single Diodes Procurement Notes

Verify the specific ordering suffix /52T corresponds to the 7-inch diameter plastic tape and reel packaging configuration with a base quantity of 750 units. Confirm that the M3 designation indicates compliance with halogen-free requirements and RoHS standards. Ensure the procurement matches the exact document number 89922 specifications for the MURS240 variant rather than the MURS260.

Single Diodes Selection Notes

Select this component when designing circuits requiring a 400 V blocking voltage and 2 A continuous current handling in a compact SMB package. The 50 ns reverse recovery time makes it suitable for high-frequency switching applications where minimizing switching losses is critical. Verify thermal management requirements against the 15 °C/W junction-to-lead thermal resistance characteristic for proper heat dissipation.

Single Diodes Part Context

This part belongs to the MURS2xx-M3 series of surface-mount ultrafast plastic rectifiers from Vishay. The series includes variants such as the MURS260-M3, which shares identical mechanical dimensions and general electrical profiles but offers a higher 600 V reverse voltage rating. Both variants utilize the same DO-214AA (SMB) footprint and are designed for automated placement processes.

Single Diodes Replacement Considerations

Direct substitutes within the Vishay lineup include the MURS260-M3/52T, which provides equivalent performance with a 600 V reverse voltage rating instead of 400 V. Other manufacturers offering similar ultrafast rectifiers in the SMB package should be evaluated based on matching reverse recovery times and forward voltage specifications.
