Overview
The BY253 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features a single configuration housed in a DO-201 through-hole package. The device supports an average forward current of 3 A and a repetitive peak reverse voltage of 600 V. Key electrical parameters include a maximum surge current of 100 A, a forward voltage of 1.1 V, and a reverse current of 5 uA.
Feature Summary
- Standard silicon rectifier construction for general-purpose applications
- Isolated case connection within the DO-201 plastic housing
- Single diode configuration designed for reliable power conversion
Applications
- General purpose rectification circuits
- Power supply input stages
- DC output filtering
Procurement Notes
Verify the specific datasheet revision to confirm exact thermal resistance values and mechanical dimensions. Ensure the DO-201 lead spacing matches your PCB footprint requirements. Confirm RoHS compliance status with the manufacturer if restricted substances are a project constraint. Cross-reference the part number to distinguish it from similar series components like the BY251 or BY254.
Selection Notes
Select this component when a 3 A continuous current rating and 600 V blocking capability are required in a standard axial leaded package. Consider the 637 ns reverse recovery time for frequency limitations. Evaluate thermal management needs based on the 1.1 V forward voltage drop at full load. Compare against higher voltage variants if system transients exceed 600 V.
Part Context
This component belongs to the BY series of silicon rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings while maintaining a consistent 3 A current capacity and DO-201 form factor. It serves as a fundamental discrete semiconductor device for converting AC to DC in low-to-medium power electronic systems.
Replacement Considerations
Public confirmed substitutes include BY251 (200V) and BY254 (800V) from the same manufacturer family. Verify voltage derating requirements when substituting with different series members.
