BY255P-E3/73

Overview

The BY255P-E3/73 is a general-purpose 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 parameters include a maximum DC reverse leakage current of 5 µA at 1300 V, a typical forward voltage drop of 1.1 V at 3 A, and a reverse recovery time of 3 µs. The junction capacitance is 40 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -65°C to 175°C.

Feature Summary

• High voltage capability with 1300 V reverse voltage rating
• Low leakage current specification for efficient blocking
• Robust thermal performance supporting high junction temperatures up to 175°C

Applications

• General purpose rectification in power supplies
• High voltage AC to DC conversion circuits

Procurement Notes

Verify the exact part number suffix against official Vishay documentation to ensure correct packaging and compliance status. Confirm RoHS3 compliance requirements match project specifications. Check current availability as distribution status may vary. Validate that the DO-201AD package dimensions fit the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when high reverse voltage blocking is required alongside moderate current handling capabilities. The standard recovery speed suits applications where switching losses are not critical. Ensure the circuit design accommodates the 1.1 V forward voltage drop at full load. Verify that the axial leaded package aligns with assembly automation or manual soldering processes available in the manufacturing facility.
