Overview
The BY500-400 is a standard recovery rectifier manufactured by Diotec Semiconductor. It utilizes a DO-201 axial leaded package for through-hole mounting. The device features a maximum repetitive peak reverse voltage of 400 V and supports a maximum average forward rectified current of 3 A. Key electrical characteristics include a maximum non-repetitive peak surge forward current of 100 A, a maximum DC reverse leakage current of 5 µA at rated voltage, and a typical junction operating temperature range from -55°C to +175°C.
Feature Summary
- High thermal stability with a maximum junction temperature rating of 175°C
- Robust surge current handling capability for transient protection
- Low reverse leakage current ensuring efficient blocking performance
Applications
- General-purpose low-power rectification in AC/DC converters
- Power supply circuits operating at line frequencies
- Battery charging systems requiring reliable DC conversion
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Diotec Semiconductor before procurement. Confirm that the DO-201 package dimensions match your PCB footprint requirements. Ensure the 400V reverse voltage rating provides adequate margin for your circuit's peak inverse voltage conditions. Check for any specific automotive or industrial qualification certifications if required for your application environment.
Selection Notes
Select this component when a 3 A continuous current rating and 400 V blocking voltage are required in an axial package. Consider the 175°C junction temperature limit for high-temperature environments. Evaluate the standard recovery time against switching frequency requirements; it is suitable for low-frequency applications. Compare physical size constraints against alternative packages like DO-201AD or SMA if space is limited.
Part Context
This part belongs to Diotec Semiconductor's general-purpose rectifier diode family. These components are designed for broad industrial and consumer electronics applications. The series offers various voltage ratings while maintaining consistent current handling capabilities. The DO-201 package provides mechanical robustness for through-hole assembly processes commonly used in power supply manufacturing.
