MURS540A-BP

Single Diodes Overview

The MURS540A-BP is a 5 Amp, 400 Volt Fast Recovery Epitaxial Diode (FRED) manufactured by Micro Commercial Components. It utilizes a planar structure die with soft recovery characteristics to minimize switching losses and enhance efficiency. The component operates within a junction temperature range of -55°C to +175°C and features a maximum thermal resistance of 2°C/W from junction to case. Key electrical parameters include a typical reverse recovery time of 25ns at 25°C and a peak forward surge current rating of 70A.

Single Diodes Feature Summary

• Ultrafast recovery time and low switching losses for high efficiency
• Soft recovery characteristics to reduce electromagnetic interference
• Halogen-free construction available upon request
• Epoxy meets UL 94 V-0 flammability rating

Single Diodes Applications

• High-frequency power supply circuits
• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Snubber circuits requiring fast recovery

Single Diodes Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors due to counterfeiting risks. Confirm the specific suffix requirements, such as adding '-HF' for halogen-free versions. Ensure compliance with RoHS standards indicated by the '-BP' suffix. Request traceability documentation to guarantee genuine parts meeting quality handling standards.

Single Diodes Selection Notes

Select this component for applications requiring fast recovery times under 35ns and low reverse leakage currents. Consider the TO-220AC package for through-hole mounting and adequate heat dissipation up to 160°C case temperature. Evaluate derating curves for average forward current based on ambient operating conditions. Verify voltage ratings match circuit peak reverse voltages.

Single Diodes Part Context

This device belongs to the MURS series of FRED rectifiers designed for minimizing energy losses in high-frequency applications. The MURS540A specifically targets 5 Ampere current levels with 400 Volts blocking capability. It serves as a replacement for standard recovery diodes where faster switching speeds are required to improve overall system performance and reduce thermal stress.

Single Diodes Replacement Considerations

Check datasheets for equivalent part numbers offering similar 5A/400V specifications and comparable reverse recovery times. Ensure pinout compatibility with the TO-220AC package if direct substitution is planned. Verify that alternative components meet the same thermal resistance and flammability rating requirements.
