BY2000

Overview

The BY2000 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 3 A and a peak repetitive reverse voltage (VRRM) ranging from 200 V to 2000 V, with the specific BY2000 variant rated at 2000 V. The device utilizes a DO-201 plastic case and supports a maximum junction temperature of 175°C. Key electrical characteristics include a forward voltage below 1.1 V at 3 A, a typical reverse recovery time of 1500 ns, and a peak forward surge current capability of 110 A for 8.3 ms half-sine waves.

Feature Summary

• High voltage blocking capability up to 2000 V in a compact axial package
• Robust surge handling with high non-repetitive peak forward current rating
• Standard recovery speed suitable for general-purpose power conversion
• Extended thermal stability allowing operation at elevated junction temperatures

Applications

• General purpose rectification in AC/DC power supplies
• Freewheeling diodes in inductive load circuits
• Polarity protection in DC power input stages
• Buck converters and synchronous rectification replacement

Procurement Notes

Verify the exact voltage sub-code suffix when ordering, as the BY2000 series encompasses multiple voltage ratings from 200 V to 2000 V. Confirm that the DO-201 axial leaded package aligns with your PCB footprint requirements. Ensure the selected component meets the specific thermal derating curves required for your ambient operating conditions to maintain reliability.

Selection Notes

Select this component for applications requiring high reverse voltage isolation in a through-hole configuration. Consider the 1500 ns reverse recovery time when designing for higher frequency switching, as it may introduce switching losses compared to fast recovery alternatives. Evaluate the thermal resistance to ambient to ensure adequate heat dissipation without excessive heatsinking.

Part Context

This part belongs to Diotec's standard silicon rectifier lineup, designed for commercial and industrial grade reliability. It serves as a robust solution for medium-power applications where cost-effectiveness and proven performance are prioritized over ultra-fast switching speeds. The DO-201 package provides mechanical durability for manual or automated through-hole assembly processes.

Replacement Considerations

Cross-reference with other 3 A, 2000 V standard recovery diodes in the DO-201 package. Verify pinout compatibility and ensure equivalent or superior reverse recovery time and forward voltage specifications if substituting in high-frequency designs.
