KBPC2504-G

Overview

The KBPC2504-G is a single-phase bridge rectifier manufactured by Comchip Technology. It utilizes glass passivated die construction and features an integrally molded heatsink for effective thermal management. The device supports a maximum average forward output rectified current of 25 A and offers a repetitive peak reverse voltage rating of 400 V. It operates within a junction temperature range of -55°C to +175°C and complies with RoHS standards.

Feature Summary

• Glass passivated die construction ensures high reliability and long-term stability under varying electrical conditions.
• Integrally molded heatsink design provides very low thermal resistance for maximum heat dissipation during operation.
• High surge current capability allows the component to withstand transient overloads without failure.
• Plastic material carries UL flammability recognition rated at 94V-0 for enhanced safety compliance.

Applications

• General purpose AC to DC power supply conversion circuits
• Battery charging systems requiring robust rectification
• Industrial power supplies operating in high-temperature environments

Procurement Notes

Verify the specific suffix G against the manufacturer's official datasheet to confirm RoHS compliance status. Ensure the ordering part number matches the exact voltage and current ratings required for the target application circuit. Cross-reference the package dimensions with PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a 25 A continuous current rating and 400 V reverse voltage blocking capability are required. The integrated heatsink makes it suitable for applications where external cooling solutions are impractical. Verify that the operating environment does not exceed the maximum junction temperature limit of 175°C.

Part Context

This component belongs to the KBPC series of bridge rectifiers from Comchip Technology. The series is designed for general-purpose power applications, offering a balance of high current handling and compact packaging. The KBPC2504-G variant specifically addresses needs for 400 V isolation in medium-power rectification tasks.

Replacement Considerations

Compatible substitutes include the GBPC2504 from ETC2, which shares identical 25 A and 400 V ratings. Other equivalents may include components from Littelfuse or TE Connectivity within the same current and voltage class, provided pinout compatibility is verified.
