Overview
The MURSB2040CTA-TP is a dual common cathode ultra-fast recovery rectifier manufactured by Micro Commercial Components. It utilizes silicon planar technology and is housed in a D2PAK-3 (TO-263-3) surface-mount package. The device is rated for a continuous forward current of 20 Amperes per diode and supports a repetitive peak reverse voltage of 400 Volts. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 150 Amperes, a typical forward voltage drop of 1.15 Volts at full load, and a low reverse leakage current of 5 microamperes. The unit operates within a temperature range of -55°C to +150°C junction temperature.
Feature Summary
- Dual common cathode configuration providing two independent rectifying elements in a single package
- Ultra-fast recovery characteristics designed for high-frequency switching applications
- Surface-mount construction utilizing the D2PAK-3 leaded package for efficient thermal dissipation
- Silicon planar technology ensuring robust performance under high surge current conditions
Applications
- High-frequency DC-to-DC converter circuits
- Free-wheeling rectification in power supply designs
- Polarity protection in electronic systems
- General purpose rectification in industrial equipment
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's official documentation to confirm compliance with RoHS directives and halogen-free status. Ensure the ordering part number matches the required D2PAK-3 package variant. Cross-reference the datasheet revision date to validate that all electrical parameters align with current production standards before finalizing procurement specifications.
Selection Notes
Select this component when a dual common cathode arrangement is required for synchronous rectification or bridge configurations in space-constrained designs. The TO-263-3 package offers superior thermal management compared to smaller SMD footprints. Evaluate the 400V rating against system voltage spikes to ensure adequate safety margins. Confirm that the 20A current capability meets the peak load requirements of the target application circuit.
Part Context
This component belongs to the MURSB series of ultra-fast recovery rectifiers from Micro Commercial Components. The series is engineered for efficiency in modern power conversion topologies. The MURSB2040CTA-TP specifically addresses the need for high-current handling in a compact surface-mount form factor, bridging the gap between through-hole reliability and SMD integration density.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Generic replacements must match the 20A/400V rating, D2PAK-3 footprint, and ultra-fast recovery speed. Verify pinout compatibility and thermal resistance values to ensure seamless integration without redesigning the PCB layout.
