Overview
The KBPC2508W-G is a single-phase bridge rectifier manufactured by Comchip Technology. It features an average forward current of 25 A and a peak repetitive reverse voltage of 800 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and a surge current capability of 400 A. Electrical characteristics include a maximum reverse leakage current of 10 uA. The component operates within a temperature range from -55 °C to +150 °C junction temperature. Physical dimensions are 28.8 mm in length, 28.8 mm in width, and 11.23 mm in height, with a unit weight of 26 g.
Feature Summary
- Integrally molded epoxy case designed for high isolation voltage between the case and leads.
- Glass passivated die construction ensures low reverse leakage current stability.
- Screw mount installation style facilitates secure attachment to external heat sinks.
Applications
- Power supply units requiring high voltage rectification
- Industrial motor drive systems
- Battery charging circuits
Procurement Notes
Verify the specific suffix 'W' against the manufacturer's official documentation to confirm mechanical mounting variations or thermal interface specifications. Ensure compliance with RoHS directives as indicated in the product data sheet before integration into regulated assemblies.
Selection Notes
Select this component when applications demand 800 V blocking capability combined with 25 A continuous conduction. The screw-mount configuration is suitable for designs utilizing external cooling solutions rather than PCB copper plane dissipation alone.
Part Context
This part belongs to the KBPC series of glass passivated bridge rectifiers. It shares the standard KBPC-W-4 package form factor with other variants in the family, differing primarily in voltage ratings and current handling capacities defined by the manufacturer's naming convention.
Replacement Considerations
Consult official substitution lists for equivalent parts with matching 25 A and 800 V ratings. Verify pinout compatibility and thermal resistance values before replacing the original component in existing hardware designs.
