Overview
The BY500-1000 is a fast recovery rectifier diode manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 5 A and a peak forward surge current (IFSM) of 220 A at 60 Hz. The device has a maximum repetitive reverse voltage rating of 1000 V, with a typical junction capacitance of 15 pF at 4 V reverse bias. Forward voltage is less than 1.3 V at 5 A, and leakage current is under 5 µA. Reverse recovery time is less than 200 ns. Thermal resistance from junction to ambient is less than 19 K/W, while junction-to-lead resistance is below 8 K/W. Operating and storage temperatures range from -50°C to +175°C.
Feature Summary
- Fast recovery characteristics with reverse recovery time under 200 ns
- High thermal stability supporting operation up to 175°C
- Robust surge handling capability with 220 A peak forward surge current
Applications
- High-frequency switching power supplies
- Free-wheeling rectification in DC-DC converters
- Polarity protection circuits
- General-purpose rectification in industrial electronics
Procurement Notes
Verify the specific suffix code against official Diotec documentation to confirm the exact reverse voltage rating, as the BY500 series covers multiple voltage grades. Confirm RoHS compliance status and packaging options directly with the manufacturer or authorized distributors before ordering. Ensure thermal management design accounts for the specified junction-to-ambient thermal resistance limits under actual operating conditions.
Selection Notes
Select this component when a 5 A continuous current rating and high-voltage blocking capability are required in a compact axial package. Consider the low reverse recovery time for efficiency in high-frequency applications. Evaluate thermal derating curves if ambient temperatures exceed standard conditions. Compare junction capacitance requirements against signal integrity needs in sensitive circuits.
Part Context
This part belongs to the BY500 series of fast recovery rectifiers from Diotec Semiconductor. The series offers various voltage ratings tailored for different power supply designs. These diodes utilize standard axial leaded packaging suitable for through-hole mounting technologies commonly found in legacy and robust industrial equipment designs.
Replacement Considerations
Check datasheets for equivalent 5 A fast recovery diodes with matching voltage ratings and reverse recovery times. Verify pinout compatibility and thermal resistance specifications to ensure direct substitution without circuit redesign.
