MURS2020FCTA-BP

Overview

The MURS2020FCTA-BP is a 20 Amp, 200 Volt Fast Recovery Epitaxial Diode (FRED) manufactured by Micro Commercial Components. It utilizes an ultrafast recovery time and soft recovery characteristics to minimize switching losses in high-frequency applications. The device features a planar structure die with low reverse leakage current of 5µA at rated voltage. Electrical parameters include a maximum RMS voltage of 140V, DC blocking voltage of 200V, and peak forward surge current of 120A. Typical reverse recovery time is 25ns at 25°C, rising to 35ns at 125°C. Forward voltage drop is typically 0.86V at 10A. Thermal resistance from junction to case is 4°C/W.

Procurement Notes

Verify the authenticity of the MURS2020FCTA-BP through authorized MCC distributors or direct purchase from Micro Commercial Components. Counterfeit components are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the presence of the -BP suffix for bulk packaging and ensure compliance with RoHS standards. Request original datasheets matching Rev.3-3-08252022 during procurement to validate technical specifications.

Selection Notes

Select this component for applications requiring fast recovery times under 35ns and average forward currents up to 20A. The ITO-220AB package supports high thermal performance with a junction-to-case resistance of 4°C/W. Ensure operating temperatures remain within the -55°C to +175°C range. Consider the 120A surge capability for transient protection needs. Verify that the 200V reverse voltage rating exceeds the circuit's peak repetitive reverse voltage requirements.

Part Context

This rectifier belongs to the MURS series of FRED devices from Micro Commercial Components. It is designed for efficiency-critical environments where switching speed directly impacts thermal management. The ITO-220AB housing provides robust mechanical stability for through-hole mounting. The product line emphasizes low reverse leakage and high surge handling capabilities compared to standard recovery diodes.

Replacement Considerations

Cross-reference with other 20A, 200V FRED diodes in the ITO-220AB package. Verify pinout compatibility and thermal resistance values before substitution. Ensure replacement parts meet the same reverse recovery time and forward voltage specifications to maintain circuit performance.
