Overview
The MURS2040CTA-BP is a 20 Amp, 400 Volt ultrafast recovery rectifier manufactured by Micro Commercial Components. It utilizes a planar die structure and is housed in a TO-220AB package. The device features an operating junction temperature range from -55°C to +175°C with a maximum thermal resistance of 2°C/W. Electrical characteristics include a typical reverse recovery time of 25ns at 25°C and a peak forward surge current capability of 120A.
Feature Summary
- Ultrafast recovery time with soft recovery characteristics
- Planar structure die design for high reliability
- Low switching losses and low reverse leakage current
- Epoxy meets UL 94 V-0 flammability rating
Applications
- High frequency DC/DC converters
- Free wheeling diodes in PWM applications
- Inverter circuits
- High efficiency power supplies
Procurement Notes
Verify the authenticity of the MURS2040CTA-BP component by purchasing directly from Micro Commercial Components or their authorized distributors. MCC explicitly warns against unauthorized sources due to counterfeit proliferation risks. Ensure the ordering suffix matches requirements, as adding "-HF" denotes halogen-free compliance. Confirm that the bulk packaging specifications align with your assembly needs before finalizing orders.
Selection Notes
Select this component when designing circuits requiring fast switching speeds and low reverse recovery charge. The TO-220AB package supports efficient heat dissipation via heatsink mounting. Consider the 20A average forward current rating relative to case temperature derating curves. Verify that the 400V repetitive peak reverse voltage meets the circuit's maximum blocking requirements under all operating conditions.
Part Context
This part belongs to the MURS2040 series of FRED (Fast Recovery Epitaxial Diode) rectifiers from Micro Commercial Components. The series is characterized by ultrafast recovery times suitable for modern high-frequency power conversion topologies. The specific model integrates a robust planar structure designed to minimize switching losses while maintaining high surge current capabilities.
Replacement Considerations
Consult official datasheets for cross-referencing. No public substitute part numbers are confirmed in the provided documentation.
