Overview
The BY252P-E3/54 is a standard recovery rectifier manufactured by Vishay Semiconductors. It features a single diode configuration housed in a DO-201AD axial through-hole package. Key electrical parameters include a maximum repetitive peak reverse voltage (Vr) of 400 V and an average forward rectified current (If) of 3 A. The device exhibits a forward voltage (Vf) of 1.1 V at the rated current, with a maximum non-repetitive peak forward surge current capability of 150 A. Reverse leakage current (Ir) is specified at 5 uA, and the typical reverse recovery time is 3 us. Operating temperatures range from -55 C to +150 C junction temperature.
Feature Summary
- Standard recovery rectifier design suitable for general-purpose power applications
- Lead-free construction compliant with RoHS directives
- High thermal stability supporting operation up to 150 C junction temperature
Applications
- General purpose rectification circuits
- Power supply input stages
- Freewheeling diode applications
Procurement Notes
Verify component authenticity against Vishay official documentation prior to integration. Confirm that the specific suffix /54 corresponds to the required tape and reel or cut tape packaging format for your assembly line. Ensure the ordering quantity aligns with manufacturer minimum order requirements and check for any recent product change notices affecting specifications or availability status.
Selection Notes
Select this component when a 400 V blocking voltage and 3 A continuous current rating are required in an axial leaded package. The 3 us reverse recovery time distinguishes it from ultra-fast variants, making it appropriate for lower frequency switching or mains-frequency applications where standard recovery characteristics are sufficient and cost-effective.
Part Context
This part belongs to the SUPERECTIFIER series of silicon planar power rectifiers. The BY252P variant specifically addresses the 400 V segment of the BY2xxP family, offering a balance of current handling and voltage blocking capabilities within the DO-201AD form factor commonly used in industrial and consumer electronics power supplies.
Replacement Considerations
Cross-reference with BY252GP-E3/54 for potential pin-compatible alternatives within the same manufacturer portfolio. Verify electrical parameter equivalence before substitution.
