BY299P-E3/73

Overview

The BY299P-E3/73 is a silicon rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 2 A. The device utilizes a DO-201AD axial through-hole package. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 70 A and a fast recovery time of less than or equal to 500 ns. It is designed for high efficiency applications with low forward voltage drop and low leakage current.

Feature Summary

• Fast switching capability for high efficiency
• Low forward voltage drop
• High forward surge current capability

Applications

• General purpose rectification
• Efficiency-critical power supplies
• Free wheeling diode circuits

Procurement Notes

Verify the component status as discontinued or obsolete before procurement planning. Confirm availability of direct substitutes such as the BY299P-E3/54 if the specific tape-and-reel packaging of the /73 suffix is not required. Ensure compliance with RoHS directives and check for any lead-time constraints associated with end-of-life inventory sources.

Selection Notes

Select this component when an 800 V reverse voltage rating and 2 A continuous current are required in a standard axial package. Consider the fast recovery characteristic for applications demanding reduced switching losses. Verify that the DO-201AD footprint matches the PCB design and that the thermal management supports the specified operating temperature range.

Part Context

This part belongs to the BY296P through BY299P series of soft recovery plastic rectifiers from Vishay. These devices are engineered for general-purpose applications requiring reliable performance under high surge conditions. The series emphasizes solderability and compliance with environmental standards, making them suitable for broad industrial and consumer electronics usage.

Replacement Considerations

Direct substitute: BY299P-E3/54. Verify package compatibility and electrical equivalence before substitution.
