BY500-200-E3/54

Overview

The BY500-200-E3/54 is a soft recovery fast-switching silicon rectifier diode manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 5.0 A and a maximum repetitive peak reverse voltage of 200 V. The device is housed in a DO-201AD plastic package with matte tin-plated leads. 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 junction capacitance of 28 pF. It supports a peak forward surge current of 200 A and operates within a junction temperature range of -50 °C to +125 °C.

Feature Summary

• Fast switching performance optimized for high efficiency applications
• Low forward voltage drop to minimize conduction losses
• Low leakage current ensuring stable operation under reverse bias
• High forward surge capability for robust transient handling

Applications

• Medium frequency rectification in switching mode power supplies
• Inverter and converter circuits
• TV scanning circuits
• Ultrasonic systems
• Speed controlled DC motors

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration, as the /54 suffix indicates reel delivery. Confirm RoHS compliance status and material categorization requirements against project specifications. Ensure thermal management designs account for the specified thermal resistance from junction to ambient. Validate that the component meets all environmental operating limits for the intended application environment.

Selection Notes

Select this component when a 5 A current rating and 200 V blocking voltage are required in a DO-201AD through-hole package. Consider the 200 ns reverse recovery time for medium-frequency switching applications. Evaluate the thermal resistance characteristics if heatsinking or specific lead lengths are necessary for the design. Compare against other voltage variants in the BY500 series if different reverse voltage ratings are needed.

Part Context

This part belongs to the BY500 series of soft recovery fast-switching plastic rectifiers from Vishay General Semiconductor. The series includes variants with reverse voltages ranging from 100 V to 800 V, all sharing similar current and surge capabilities. These devices are designed for general-purpose rectification where fast switching and low loss are beneficial. The series utilizes a single die configuration within a molded epoxy body meeting UL 94 V-0 flammability ratings.

Replacement Considerations

Direct substitutes within the same family include BY500-100, BY500-400, BY500-600, and BY500-800, which share identical mechanical and current ratings but differ in reverse voltage. Verify that any replacement maintains the DO-201AD package and pinout compatibility. Ensure the alternative component meets the same thermal and electrical performance criteria for the specific circuit application.
