BY255P-E3/54

Overview

The BY255P-E3/54 is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 1300 V and an average forward rectified current of 3 A. The device utilizes a DO-201AD axial through-hole package. Key electrical characteristics include a typical forward voltage of 1.1 V at 3 A, a reverse leakage current of 5 µA at 1300 V, and a reverse recovery time of 3 µs. The junction capacitance is specified as 40 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -65°C to 175°C.

Procurement Notes

Verify the exact part number against official Vishay documentation, as the specific suffix P-E3/54 may not be explicitly listed in all public databases compared to similar variants like GP or E3/73. Confirm availability status, as related components in this series have been subject to end-of-life notifications. Ensure compliance requirements match project specifications before procurement.

Selection Notes

Select this component for designs requiring high-voltage blocking capabilities up to 1300 V with moderate current handling. The 3 µs reverse recovery time suits standard frequency applications rather than high-speed switching. Verify that the DO-201AD package dimensions fit the PCB layout constraints and that the thermal management supports the specified junction temperature range.

Part Context

This diode belongs to the SUPERECTIFIER family from Vishay, designed for robust performance in demanding environments. The series emphasizes reliability through glass passivation and cavity-free construction. It serves as a general-purpose solution for industrial and consumer electronics requiring durable rectification under high reverse bias conditions.
