KBPC2506-G

Overview

The KBPC2506-G is a single-phase silicon bridge rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 25 A and a repetitive peak reverse voltage of 600 V. The device utilizes a GBPC-style plastic package with an integrated metal heat sink for efficient thermal management. Key electrical parameters include a maximum non-repetitive peak forward surge current of 300 A at 8.3 ms single half-sine wave, a maximum DC forward voltage drop of 1.2 V at rated current, and a maximum DC reverse leakage current of 5 µA at 600 V. The component supports a wide operating junction temperature range from -55 °C to +150 °C and meets UL flammability classification 94V-0 standards.

Feature Summary

• Integrated metal heat sink embedded within the bridge encapsulation for enhanced thermal dissipation
• Molded plastic case constructed from materials classified as UL 94V-0 flammability resistant
• Electrically isolated base capable of withstanding high isolation voltages
• Designed for flexible mounting in any orientation due to robust mechanical construction

Applications

• High-current AC to DC power supply conversion circuits
• Battery charging systems requiring robust surge handling
• Industrial motor drive rectification stages

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the KBPC2506 part number is widely used across multiple semiconductor vendors including Panasonic, Vishay, and Good-Ark. Confirm that the suffix '-G' corresponds to Comchip Technology's specific ordering code and RoHS compliance status. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications and pinout configurations before finalizing procurement orders.

Selection Notes

Select this component for applications demanding a 25 A continuous current rating with 600 V blocking capability in a through-hole configuration. The integrated heatsink design makes it suitable for space-constrained boards where external cooling solutions are impractical. Ensure the PCB layout accommodates the specific terminal spacing of the GBPC package style and provides adequate copper area for thermal transfer given the 1.2 V forward voltage drop characteristics under load.

Part Context

This component belongs to the family of high-current single-phase bridge rectifiers designed for general-purpose power electronics. It shares the standard GBPC form factor with other industry-standard devices, allowing for potential physical interchangeability with similar packages from different manufacturers. The 25 A/600 V rating positions it between lower-current small signal bridges and higher-power industrial modules, serving mid-range power conversion needs.

Replacement Considerations

Direct substitutes include the Panasonic BR2506, Vishay VS-KBPC2506, and Good-Ark KBPC2506. Verify that replacement parts maintain the same 25 A current rating, 600 V reverse voltage, and compatible GBPC package dimensions. Check for equivalent thermal resistance values and forward voltage drops to ensure circuit performance remains within design tolerances.
