Overview
The BY880-800 is a standard recovery rectifier manufactured by Diotec Semiconductor. It features an 8 A average forward current rating and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a D5.4x7.5 through-hole package configuration. Key electrical characteristics include a maximum forward voltage drop of 1.1 V, a peak non-repetitive surge current capacity of 400 A, and a maximum reverse leakage current of 5 µA.
Feature Summary
- Standard recovery rectifier technology for general-purpose power conversion
- Through-hole mounting style for robust mechanical attachment
- Single diode configuration with high surge current handling capability
Applications
- General purpose rectification in AC/DC power supplies
- Freewheeling diodes in inductive load circuits
- Reverse polarity protection in DC power systems
Procurement Notes
Verify the specific part number suffix against official Diotec Semiconductor documentation to confirm exact electrical tolerances and marking codes. Ensure the procurement channel provides valid manufacturer traceability. Confirm RoHS compliance status directly from the latest datasheet revision before finalizing orders.
Selection Notes
Select this component when an 8 A current rating and 800 V blocking voltage are required in a through-hole form factor. Compare the 1.1 V forward voltage drop against system efficiency targets. Verify that the 400 A surge rating exceeds the expected inrush currents in the target application circuit design.
Part Context
This component belongs to the BY series of standard recovery rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. The BY880-800 specifically addresses applications requiring high voltage isolation within a compact axial leaded footprint.
Replacement Considerations
Cross-reference with BY880-600 or BY880-1000 if voltage requirements differ. Verify pinout compatibility with existing PCB layouts. Confirm thermal management requirements match the original design specifications.
