BY297P-E3/54

Overview

The BY297P-E3/54 is a general-purpose fast recovery rectifier diode manufactured by Vishay General Semiconductor. It utilizes the DO-201AD (DO-4) axial leaded package for through-hole mounting. The device is rated for a maximum repetitive reverse voltage of 200V and an average forward rectified current of 2A. Key electrical characteristics include a maximum forward voltage drop of 1.3V at 3A and a reverse recovery time of 500ns. These specifications define its performance envelope for high-speed switching applications in power conversion circuits.

Feature Summary

• Fast recovery characteristic with a reverse recovery time of 500ns
• General purpose rectification capability for power supplies
• Robust axial leaded construction for reliable through-hole integration

Applications

• General purpose rectification in power supply circuits
• Inverter and converter freewheeling diode applications
• High speed switching circuits requiring fast recovery

Procurement Notes

Verify component authenticity as this part number is listed as obsolete and no longer manufactured by the original producer. Confirm availability of verified substitutes such as the EGP20D series if new production units are required. Ensure datasheet alignment for critical parameters like reverse recovery time and forward voltage when selecting alternatives to maintain circuit integrity.

Selection Notes

Select this component for applications requiring 200V blocking voltage and 2A continuous current handling. The 500ns reverse recovery time makes it suitable for faster switching frequencies compared to standard rectifiers. Consider thermal management requirements associated with the DO-201AD package and ensure the operating temperature range aligns with system constraints before finalizing the design.

Part Context

This diode belongs to the BY2xxP series of fast recovery rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent current handling and recovery characteristics. The E3 suffix indicates halogen-free and RoHS compliance, while /54 denotes the specific tape and reel packaging configuration for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers include the EGP20D series. Verify that alternative devices match the 200V reverse voltage, 2A forward current, and 500ns reverse recovery time specifications to ensure functional equivalence in existing designs.
