Overview
The BY254GP-E3/73 is a silicon rectifier diode manufactured by Vishay General Semiconductor. It features a standard recovery speed with a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 3 A. The device utilizes a DO-201AD plastic package for through-hole mounting. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 100 A, a low leakage current of less than 0.1 µA, and a maximum junction temperature rating of 175 °C.
Feature Summary
- Superrectifier structure designed for high reliability applications
- Cavity-free glass-passivated junction construction
- Low forward voltage drop characteristic
- Low leakage current performance
Applications
- General purpose rectification
- Free wheeling diode circuits
Procurement Notes
Verify the specific suffix against official documentation to confirm packaging configuration. The BY254GP-E3/73 designation indicates a specific tape and reel format distinct from other variants like the /68 or bulk options. Ensure the component matches the required RoHS compliance status and lead finish specifications defined in the manufacturer's datasheet before finalizing procurement orders.
Selection Notes
Select this component when an 800 V blocking capability and 3 A continuous current rating are required in a DO-201AD package. The glass passivation offers superior stability compared to epoxy encapsulated alternatives. Consider the 175 °C junction temperature limit for high-thermal environments. Verify that the standard recovery time meets the switching frequency requirements of the target circuit design.
Part Context
This part belongs to the BY25xGP series of glass-passivated junction plastic rectifiers from Vishay. These devices share common structural features such as the Superrectifier technology and cavity-free junction design. The series spans various voltage ratings from 200 V to 1300 V while maintaining consistent current handling and package dimensions for design flexibility across different power supply architectures.
Replacement Considerations
Direct substitutes within the same family include BY251GP, BY252GP, BY253GP, and BY255GP, which offer identical current and package specifications but differ in reverse voltage ratings. Cross-brand replacements must match the DO-201AD footprint, 3 A current rating, and 800 V minimum reverse voltage requirement.
