Overview
The KBPC2504W-G is a single-phase bridge rectifier manufactured by Comchip Technology. It features an average forward current rating of 25 A and a maximum repetitive peak reverse voltage of 400 V. The device exhibits a typical forward voltage drop of 1.1 V at rated current and supports a maximum non-repetitive surge current of 400 A. It operates within a temperature range from -55 °C to +150 °C junction temperature. The component utilizes a screw mount installation style with through-hole termination in the KBPC-W-4 package, measuring 28.8 mm in length and width, and 11.23 mm in height.
Feature Summary
- Glass passivated die construction for enhanced reliability
- Integrally molded heatsink design for efficient thermal dissipation
- High surge current capability for robust performance under transient loads
Applications
- AC to DC power supply circuits
- Battery charging systems
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the specific part number against official manufacturer documentation to ensure compliance with required electrical ratings and mechanical specifications. Confirm RoHS status and packaging details directly with authorized distributors or the manufacturer prior to procurement to avoid discrepancies.
Selection Notes
Select this component when a 25 A current capacity and 400 V reverse voltage rating are required in a screw-mount configuration. Ensure the application environment remains within the specified operating temperature range and that adequate heat sinking is provided to maintain junction temperatures below the maximum limit during continuous operation.
Part Context
This component belongs to the KBPC series of glass-passivated bridge rectifiers produced by Comchip Technology. The series offers various current and voltage combinations, with the KBPC2504W-G specifically designed for applications requiring 25 A and 400 V. It shares common mechanical dimensions and mounting styles with other variants in the KBPC family.
Replacement Considerations
Compatible substitutes include the KBPC2504 from other manufacturers offering identical 25 A and 400 V ratings in the same KBPC-W-4 package. Verify pinout compatibility and thermal resistance characteristics before substitution.
