MURSB1660CTA-TP

Overview

The MURSB1660CTA-TP is a dual common cathode ultrafast recovery rectifier manufactured by Micro Commercial Components. It features a 600 V peak repetitive reverse voltage and an average forward current of 16 A per device (8 A per diode). The component utilizes a D2PAK surface-mount package with four terminals, where pins 1 and 3 serve as anodes and pins 2 and 4 act as the common cathode. Electrical characteristics include a maximum reverse recovery time of 35 ns at 25°C and a typical forward voltage of 1.6 V at 8 A. The device supports an operating junction temperature range from -55°C to 175°C.

Feature Summary

• Ultrafast recovery time for low switching losses
• Planar structure die with soft recovery characteristics
• Halogen-free green device compliant with RoHS standards

Applications

• High frequency power supply circuits
• DC-DC converter modules
• Free-wheeling rectification in inductive loads

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement channels to avoid counterfeit components. Confirm the specific suffix 'TP' indicates lead-free finish and RoHS compliance. Ensure the ordering quantity matches the specified packing options, such as tape and reel or bulk packaging, to align with manufacturing requirements.

Selection Notes

Select this component when high efficiency and fast switching speeds are required in compact surface-mount designs. The D2PAK package offers improved thermal performance compared to standard TO-220 variants. Consider the 16 A total current rating and 600 V blocking capability to ensure adequate margin for the target application's voltage and current stress levels.

Part Context

This part belongs to the MURSB series of FRED rectifiers from Micro Commercial Components. It is designed for applications requiring superior switching performance over standard recovery diodes. The series emphasizes low reverse leakage and high reliability under high-temperature conditions, making it suitable for modern power electronics.

Replacement Considerations

Direct substitutes must match the 600V/16A rating, D2PAK-4 package, and ultrafast recovery specifications. Verify pinout compatibility, specifically the dual common cathode configuration, before implementation.
