BY253GPHE3/54

Overview

The BY253GPHE3/54 is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 3 A. The device exhibits a maximum forward voltage of 1.1 V at 3 A and a reverse leakage current of 5 µA at 600 V. Capacitance is specified as 40 pF at 4 V and 1 MHz. The component utilizes a DO-201AD axial through-hole package and operates within a junction temperature range of -65°C to 175°C.

Feature Summary

• High thermal stability with a junction temperature rating up to 175°C
• Robust construction in a DO-201AD axial leaded package for through-hole mounting
• Low reverse leakage current characteristics at rated voltage

Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching applications
• DC-AC conversion stages requiring high thermal endurance

Procurement Notes

Verify the specific suffix HE3 against official Vishay documentation to confirm hermetic sealing or enhanced reliability specifications, as suffixes often denote distinct manufacturing processes or material compositions. Cross-reference the part number with current manufacturer lifecycle notices to determine active production status or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when circuit requirements demand a 600 V blocking capability combined with a 3 A continuous current handling capacity. The DO-201AD package is suitable for applications requiring robust mechanical mounting and high thermal dissipation. Ensure the operating environment remains within the specified -65°C to 175°C junction temperature range to maintain performance integrity.

Part Context

This device belongs to the SUPERECTIFIER series from Vishay, designed for general-purpose rectification tasks. The BY253 variant specifically addresses applications needing higher current ratings than standard 1 A diodes while maintaining reliable performance at elevated temperatures. The product line emphasizes durability and consistent electrical characteristics across varying thermal conditions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative components by matching key parameters such as 600 V reverse voltage, 3 A forward current, DO-201AD package dimensions, and maximum junction temperature limits.
