Overview
The MURHB840CTG is an ultrafast recovery rectifier manufactured by onsemi, featuring a dual common cathode configuration. It provides a maximum repetitive peak reverse voltage of 400 V and supports an average forward current of 4 A per diode. The device exhibits a typical forward voltage drop of 2.2 V at rated current and a maximum reverse leakage current of 10 uA. Its ultrafast recovery characteristics include a maximum reverse recovery time of 28 ns and a peak forward surge current capability of 100 A. Designed for surface mount applications, it utilizes the D2PAK package and operates within a junction temperature range from -65 °C to +175 °C.
Feature Summary
- Ultrafast recovery performance with minimal switching losses
- Dual common cathode topology for bridge or push-pull circuits
- High thermal stability suitable for elevated operating environments
Applications
- High-frequency DC-DC converters
- Free-wheeling rectification in power supplies
- Polarity protection circuits
Procurement Notes
Verify the exact part number against official manufacturer documentation, as suffixes indicate specific packaging or tape-and-reel configurations that may differ from standard tube packaging. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as supply chain conditions vary. Ensure the selected variant matches the required thermal and electrical specifications for the target application.
Selection Notes
Select this component for designs requiring fast switching speeds and high reliability in compact surface-mount layouts. The dual common cathode arrangement simplifies circuit design for full-wave rectification or synchronous rectification alternatives. Evaluate thermal management requirements based on the D2PAK package's heat dissipation capabilities under continuous load conditions.
Part Context
This device belongs to the MURH series of ultrafast recovery rectifiers from onsemi, engineered for efficiency in high-frequency power conversion. The series is characterized by low reverse recovery charge and short tail current, reducing electromagnetic interference and switching losses compared to standard recovery diodes.
Replacement Considerations
Compatible substitutes include MURH860CTG (600V rating) and MURH840CT (non-RoHS version). Verify pinout compatibility and thermal resistance values when cross-referencing with other manufacturers' ultrafast rectifiers.
