BY500-800-E3/54

Overview

The BY500-800-E3/54 is a silicon rectifier diode from the Vishay General Semiconductor BY500 series, housed in a DO-201AD plastic package. It features a maximum average forward rectified current of 5.0 A and a maximum repetitive peak reverse voltage of 800 V. The device supports a peak forward surge current of 200 A and operates within a junction temperature range of -50 °C to +125 °C. Key electrical characteristics include a maximum instantaneous forward voltage of 1.35 V at 5.0 A, a maximum DC reverse current of 10 μA at rated voltage, and a typical reverse recovery time of 200 ns.

Feature Summary

• Fast switching performance optimized for high efficiency applications
• Low leakage current capability under rated blocking voltage conditions
• High forward surge current handling capacity for transient protection

Applications

• Medium frequency rectification in switching mode power supplies
• Inverter and converter circuits requiring fast recovery
• TV scanning and ultrasonic system power stages
• Speed controlled DC motor drive freewheeling paths

Procurement Notes

Verify that the specific ordering suffix /54 corresponds to the required tape and reel packaging configuration before finalizing procurement orders. Confirm RoHS compliance status aligns with project environmental requirements. Ensure technical specifications meet the thermal and electrical demands of the target application circuit design.

Selection Notes

Select this component when an 800 V reverse voltage rating is necessary alongside a 5 A continuous current requirement. Consider the 200 ns reverse recovery time for medium frequency switching operations. Evaluate the DO-201AD package constraints against available board space and thermal dissipation capabilities for the intended installation environment.

Part Context

This part belongs to the BY500 series of soft recovery fast-switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 100 V to 800 V. All members share identical current ratings and package dimensions, differing primarily in their breakdown voltage specifications for various power supply designs.

Replacement Considerations

Direct substitutes within the same family include BY500-600-E3/54 or BY500-400-E3/54 if lower voltage ratings are acceptable. Cross-brand replacements must match the 5 A current, 800 V voltage, and DO-201AD package form factor.
