Overview
The MURHB860CTT4G is a dual common cathode ultrafast recovery rectifier from the MEGAHERTZ series. It features a 600V repetitive peak reverse voltage and a continuous forward current of 4A per element. The device utilizes a D2PAK surface-mount package with an internal cathode connection. Key electrical characteristics include a maximum non-repetitive peak surge current of 100A, a typical forward voltage of 2.8V at rated current, and a fast reverse recovery time of 35ns. It operates within a junction temperature range of -65°C to +175°C.
Feature Summary
- Ultrafast recovery performance for high-frequency switching applications
- Dual common cathode configuration in a single surface-mount package
- High thermal stability supporting operation up to 175°C junction temperature
Applications
- High-frequency DC-DC converters
- Free-wheeling rectification in power supplies
- Isolated output rectification in flyback topologies
Procurement Notes
Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required voltage and current ratings for the target circuit design. Cross-reference the datasheet revision date to guarantee compliance with current manufacturing standards and material declarations.
Selection Notes
Select this component when a compact dual-diode solution is required for high-voltage, moderate-current applications. The D2PAK package offers superior thermal dissipation compared to smaller SMD options. Consider the 35ns recovery time suitability for the specific switching frequency of the power converter design.
Part Context
This part belongs to the MEGAHERTZ family of ultrafast rectifiers designed for efficiency and speed. It serves as a surface-mount alternative to through-hole equivalents, facilitating automated assembly. The dual common cathode arrangement simplifies circuit layout for bridge or center-tapped configurations.
Replacement Considerations
Direct pin-compatible substitutes may include other MURH860CT variants from onsemi, such as MURH860CTG, provided the packaging format aligns with production requirements. Verify equivalent electrical parameters before substitution.
