MURB1660CT

Overview

The MURB1660CT is an ultrafast rectifier manufactured by onsemi, housed in a D2PAK (TO-263) surface-mount package. It features a dual common cathode configuration with a maximum repetitive reverse voltage of 600 V and an average forward current rating of 8 A per diode leg. The device exhibits a peak non-repetitive forward surge current capability of 100 A and a typical peak reverse recovery time of 60 ns. Operating within a junction temperature range of -65 °C to +175 °C, it maintains a maximum forward voltage of 1.5 V at 8 A and a low reverse leakage current of 10 μA.

Feature Summary

• Ultrafast recovery characteristics designed for high-frequency switching applications
• Dual common cathode configuration providing two independent rectifying elements
• Guard-ring technology incorporated for enhanced stress protection and reliability

Applications

• High-efficiency switch-mode power supplies
• Free-wheeling rectification in DC-to-DC converters
• Inverter circuits requiring fast recovery performance

Procurement Notes

Verify the specific suffix against official datasheets to confirm packaging type, as variations exist between tape-and-reel and tube formats. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer's latest documentation to confirm active status and availability before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring 600 V blocking capability with moderate current handling in a compact surface-mount footprint. The 60 ns recovery time makes it suitable for frequencies where standard fast recovery diodes may exhibit excessive losses. Consider thermal management strategies given the TO-263 package's heat dissipation characteristics relative to its power rating.

Part Context

This part belongs to onsemi's MURB series of ultrafast rectifiers, which are engineered for superior performance in demanding power electronics environments. The series offers a balance of high voltage ratings and fast switching speeds, addressing the needs of modern efficient power conversion systems. The D2PAK package provides robust mechanical stability and thermal performance compared to smaller surface-mount alternatives.

Replacement Considerations

Direct substitutes include the MURF1660CT and MURH860CT from onsemi, which share similar electrical specifications. Other manufacturers offer equivalent parts such as the MURB1660CT from Micro Commercial Components. Verify pinout compatibility and thermal resistance values when substituting across different vendors.
