Overview
The BY1800 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features a DO-201 through-hole package and provides a maximum repetitive peak reverse voltage of 1800 V with a nominal forward current of 3 A. The device exhibits a maximum forward voltage of 1.5 V at rated current and a typical reverse leakage current of 5 µA. Its maximum non-repetitive surge current capability is 70 A, and the typical reverse recovery time is 1.5 µs.
Feature Summary
- High-voltage rectification capability up to 1800 V
- Robust surge current handling for transient protection
- Standard plastic DO-201 axial leaded package
Applications
- High-voltage power supply rectification
- Industrial equipment power circuits
- General-purpose high-voltage rectifying applications
Procurement Notes
Verify the specific datasheet revision and electrical parameter tolerances against the manufacturer's official documentation before integration. Confirm that the DO-201 package dimensions and pinout align with the target PCB footprint requirements. Ensure thermal management strategies account for the forward voltage drop under continuous load conditions.
Selection Notes
Select this component when a through-hole solution is required for high-voltage applications exceeding 1000 V reverse blocking. Compare the 3 A average forward current rating against circuit load demands. Evaluate the 1.5 µs reverse recovery time suitability for the operating frequency to minimize switching losses in the specific application context.
Part Context
The BY1800 belongs to Diotec Semiconductor’s silicon rectifier portfolio, designed for general-purpose power conversion. It complements lower voltage variants within the same series, offering higher breakdown voltage ratings while maintaining similar mechanical packaging standards for consistent assembly processes across different power stages.
Replacement Considerations
Cross-reference with other 1800 V, 3 A DO-201 rectifiers from alternative manufacturers. Verify matching electrical parameters including reverse voltage, forward current, and recovery time before substitution.
