Overview
The KBPC3510W-G is a single-phase glass-passivated bridge rectifier manufactured by Comchip Technology. It features an average forward rectified current of 35 A and a maximum repetitive peak reverse voltage of 1000 V. The device utilizes a GBPC-W package with integrated heatsink for efficient thermal management. Key electrical parameters include a non-repetitive peak forward surge current of 400 A at 8.3 ms, a maximum DC forward voltage drop of 1.1 V at 35 A, and a maximum RMS isolation voltage of 2500 V between terminals and case. The component operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Glass passivation provides long-term stability and protects against mechanical stress.
- Integrated heatsink design in the molded plastic case ensures low thermal resistance.
- High surge current capability handles transient overload conditions effectively.
Applications
- AC-DC power supply circuits
- Battery chargers
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the manufacturer marking on the component body matches Comchip Technology branding. Confirm the suffix 'G' indicates lead-free compliance per RoHS standards. Check datasheet revisions for any updates to mechanical dimensions or thermal characteristics before finalizing procurement specifications.
Selection Notes
Select this component when a 1000 V blocking voltage and 35 A continuous current are required in a through-hole package. Ensure the application environment stays within the specified -55 °C to +150 °C operating temperature range. Verify that the PCB layout accommodates the GBPC-W footprint and allows for adequate airflow or mounting to the integrated heatsink.
Part Context
This part belongs to the KBPC series of high-current bridge rectifiers. The 'W' suffix typically denotes a specific terminal finish or packaging variation compared to standard KBPC models. It serves as a robust solution for medium-to-high power applications requiring reliable AC-to-DC conversion with high surge tolerance.
Replacement Considerations
Cross-reference with GBPC3510W from other manufacturers if sourcing constraints exist. Ensure substitute parts maintain identical pinout configuration, thermal resistance values, and voltage/current ratings to guarantee compatibility without circuit redesign.
FAQ
