Overview
The NRVBD640CTG-VF01 is a dual common cathode fast recovery rectifier manufactured by onsemi. It features a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 2A per diode. The device exhibits a low forward voltage drop of 1.35V at 2A and a typical reverse recovery time of 75ns. It is housed in a compact DPAK-3 surface-mount package, suitable for high-frequency switching applications requiring efficient power conversion.
Feature Summary
- Dual common cathode configuration for bridge or synchronous rectification topologies
- Fast recovery characteristics with low reverse recovery charge
- High thermal efficiency via direct PCB mounting tab
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in motor drives
- Uninterruptible Power Supply (UPS) input stages
Procurement Notes
Verify the specific suffix VF01 against the manufacturer's latest datasheet to confirm packaging details and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.
Selection Notes
Select this component when designing circuits requiring moderate current handling with fast switching speeds. The dual common cathode arrangement simplifies layout compared to discrete single diodes. Consider the thermal resistance of the DPAK package and ensure adequate copper area on the PCB for heat dissipation during continuous operation.
Part Context
This part belongs to onsemi's NRVBD series of fast recovery rectifiers. These devices are engineered for general-purpose power applications where speed and reliability are critical. The series offers various voltage and current ratings to accommodate diverse power supply designs across industrial and consumer electronics sectors.
Replacement Considerations
Consult official substitution guides for equivalent dual fast recovery diodes from onsemi or other manufacturers. Verify that any substitute matches the 400V rating, 2A current capacity, and DPAK-3 package dimensions to ensure mechanical and electrical compatibility.
