BY500-200

Overview

The BY500-200 is a silicon rectifier diode manufactured by Diotec Semiconductor, designed for general-purpose rectification applications. It features a maximum average forward rectified current of 5.0 A and a repetitive peak reverse voltage rating of 200 V. The device is housed in a DO-201AD plastic package with two terminals, suitable for through-hole mounting. Key electrical characteristics include a low leakage current of 10 µA and a maximum non-repetitive peak forward surge current of 200 A. The component supports a maximum junction temperature of 125 °C and exhibits a fast switching time of 200 ns, making it efficient for high-frequency operations.

Feature Summary

• Fast switching capability ensures high efficiency in power conversion circuits.
• Low forward voltage drop minimizes energy loss during conduction.
• Low leakage current enhances performance in high-temperature environments.
• High forward surge capability provides robust protection against transient currents.

Applications

• General-purpose rectification in power supplies
• Free-wheeling diode applications in inductive loads
• Efficiency optimization in AC-DC converters

Procurement Notes

Verify the specific manufacturer datasheet for the BY500-200 to confirm compliance with RoHS directives and lead times. Ensure the DO-201AD package dimensions match your PCB layout requirements. Cross-reference the electrical ratings, particularly the 200 V reverse voltage and 5 A forward current, against your circuit design specifications to guarantee reliable operation under expected load conditions.

Selection Notes

Select the BY500-200 when a standard recovery rectifier with moderate speed and high current handling is required. Its DO-201AD package offers mechanical stability for through-hole assembly. Consider this component for applications where low leakage and fast switching are prioritized over ultra-low forward voltage drops typical of Schottky diodes. Verify thermal management needs given the 125 °C junction temperature limit.

Part Context

The BY500-200 belongs to the BY500 series of soft recovery fast-switching plastic rectifiers produced by Vishay General Semiconductor. This series is engineered for high-efficiency applications requiring reliable performance under varying thermal conditions. The DO-201AD case provides a molded epoxy body with UL-94V-0 flammability rating, ensuring safety and durability in industrial and consumer electronics environments.

Replacement Considerations

Check for direct substitutes within the same series or equivalent packages from other manufacturers. Ensure replacement parts maintain the 200 V reverse voltage and 5 A forward current ratings. Verify that the alternative diode's switching speed and leakage current specifications meet the original design requirements for efficiency and thermal performance.
