BY500-800

Overview

The BY500-800 is a silicon rectifier diode manufactured by Vishay, housed in the DO-201AD plastic package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward current rating of 5 A. The device exhibits a maximum non-repetitive peak forward surge current of 200 A, a typical reverse leakage current of 10 µA, and a forward voltage drop of 1.35 V. Its junction temperature range extends up to 125 °C, with a specified reverse recovery time of 200 ns.

Feature Summary

• Fast switching capability designed for high efficiency applications
• Low forward voltage drop to minimize conduction losses
• Low leakage current characteristics
• High forward surge current handling capability

Applications

• Efficiency-critical power conversion circuits
• Free wheeling diode implementations
• General purpose rectification in industrial electronics

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm compliance with RoHS directives and check for specific suffix variations that may indicate lead-free plating or packaging differences. Ensure the DO-201AD package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a robust 5 A rectifier with 800 V blocking capability is required in a standard axial leaded package. Consider its 200 ns recovery time for moderate frequency switching applications. Evaluate thermal management needs as the maximum junction temperature is rated at 125 °C, which may require derating in high ambient temperature environments.

Part Context

This part belongs to the BY500 series of fast-switching plastic rectifiers from Vishay General Semiconductor. The series offers various voltage ratings ranging from 100 V to 800 V while maintaining consistent current and surge capabilities. These diodes are engineered for general-purpose rectification tasks where reliable performance and cost-effectiveness are primary design drivers.

Replacement Considerations

Cross-reference with other DO-201AD packaged 5 A, 800 V rectifiers from manufacturers such as Diotec or Onsemi. Verify electrical parameter equivalence, specifically forward voltage and reverse recovery time, to ensure circuit compatibility without redesign.
