Overview
The BY550-2000 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 5 A and a peak repetitive reverse voltage (VRRM) of 2000 V. The device has a maximum forward voltage (VF) of 1.1 V at 5 A and a typical reverse recovery time (trr) of 1500 ns. It withstands a peak forward surge current (IFSM) of 200 A for 8.3 ms or 180 A for 10 ms. Operating junction temperature ranges from -50°C to +175°C.
Feature Summary
- High voltage blocking capability rated up to 2000 V
- Robust thermal performance with a wide operating junction temperature range extending to +175°C
- Standard recovery characteristics suitable for general-purpose rectification applications
Applications
- Industrial power supplies
- General purpose rectification in high voltage circuits
- Battery chargers requiring high voltage isolation
Procurement Notes
Verify the specific part number suffix against official Diotec documentation to ensure correct voltage rating and package configuration. Confirm RoHS compliance status and lead-free availability directly with the manufacturer or authorized distributors before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring a 5 A continuous current capacity combined with a 2000 V reverse voltage rating. Ensure the application environment supports the specified thermal resistance values and that the standard 1500 ns reverse recovery time aligns with the switching frequency requirements of the target system.
Part Context
This component belongs to the BY550 series of standard recovery rectifier diodes produced by Diotec Semiconductor. The series covers various voltage ratings ranging from 50 V to 2000 V, all sharing a common 5 A average forward current rating and similar physical packaging constraints for industrial integration.
Replacement Considerations
Cross-reference with other 5 A, 2000 V standard recovery rectifiers such as those from Vishay or Littelfuse. Verify matching electrical parameters including VF, IFSM, and trr to ensure functional compatibility without circuit redesign.
