Overview
The KBPC5004-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features a forward current rating of 50 A and a peak reverse voltage of 400 V. The device exhibits a maximum forward voltage drop of 1.1 V and supports a surge current of 500 A. Operating within a temperature range of -55°C to +150°C, it utilizes a KBPC-W-4 package with screw mount installation. Key electrical parameters include a reverse leakage current of 10 uA.
Feature Summary
- High current handling capability suitable for demanding power conversion tasks
- Robust thermal performance allowing operation in extreme temperature environments
- Low forward voltage drop for improved energy efficiency
- Durable construction with high surge current tolerance
Applications
- Industrial power supply units
- Battery charging systems
- DC motor drives
Procurement Notes
Verify the specific suffix and marking on the component body to ensure exact model matching against official Comchip Technology documentation. Confirm that the procurement channel provides valid traceability and authenticity guarantees. Check for compliance with relevant environmental standards such as RoHS requirements before finalizing orders.
Selection Notes
Select this component when a 50 A continuous current and 400 V blocking voltage are required. Ensure the application environment supports the specified operating temperature range. Verify that the PCB layout or chassis design accommodates the physical dimensions and screw mounting requirements of the KBPC-W-4 package.
Part Context
This part belongs to the KBPC series of bridge rectifiers from Comchip Technology. It shares the same physical footprint and general characteristics with variants like KBPC5005W-G and KBPC5010W-G, differing primarily in their reverse voltage ratings. The series is designed for general-purpose rectification in various electronic circuits.
Replacement Considerations
KBPC5005W-G offers identical current and package specifications but with a higher 50 V reverse voltage rating. KBPC5010W-G provides the same 50 A current capacity but with a significantly higher 1 kV reverse voltage rating. Both alternatives maintain the same mechanical form factor.
