Overview
The BYW77PI-200RG is a single chip rectifier manufactured by STMicroelectronics, designed for switchmode power supplies and high-frequency DC to DC converters. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 25 A. The device utilizes the DOP3I package with insulated straight leads for through-hole mounting. Reverse leakage current is specified at 25 µA when tested at 200 V.
Feature Summary
- Single chip construction optimized for switchmode power supply applications
- Insulated lead design within the DOP3I package for enhanced safety
- Suitable for high-frequency DC to DC converter circuits
Applications
- Switchmode power supplies
- High frequency DC to DC converters
Procurement Notes
Verify the specific ordering suffix RG against the official STMicroelectronics datasheet to confirm compliance with RoHS directives and packaging specifications. Ensure the DOP3I-2 package dimensions match the target PCB footprint. Cross-reference the 200 V rating and 25 A current capacity with the actual circuit requirements to prevent derating issues during operation.
Selection Notes
Select this component when a robust, insulated rectifier is required for high-current switching applications. The DOP3I package provides mechanical stability and electrical isolation suitable for mains-connected or isolated secondary side designs. Confirm that the thermal management strategy accommodates the 25 A continuous current capability without exceeding junction temperature limits.
Part Context
This part belongs to the BYW77PI series of general-purpose rectifiers from STMicroelectronics. The series offers various voltage ratings while maintaining consistent current handling capabilities. The BYW77PI-200RG specifically addresses the 200 V breakdown requirement, distinguishing it from lower or higher voltage variants within the same product family.
Replacement Considerations
Direct substitutes include other BYW77PI series parts with identical current ratings but different voltage codes, such as the BYW77PI-400RG for higher voltage needs. Verify pinout compatibility and package insulation class before substituting with generic equivalents.
