Overview
The KBPC5008-G is a single-phase bridge rectifier manufactured by Comchip Technology, utilizing silicon planar technology. It features a forward current rating of 50 A and a peak repetitive reverse voltage of 800 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and a surge current capability of 450 A. Designed for through-hole mounting via solder pins, it operates within a temperature range of -55°C to +150°C junction temperature. The component is housed in the GBPC-W-4 package with dimensions of 28.8 mm x 28.8 mm x 8.5 mm.
Feature Summary
- High thermal stability enabling operation up to 150°C junction temperature
- Robust surge current handling capability for transient protection
- Low forward voltage drop for improved efficiency
Applications
- AC-DC power supply rectification
- Battery charging circuits
- General-purpose DC power supplies
Procurement Notes
Verify the specific datasheet version for the KBPC5008-G to confirm RoHS compliance status and exact pinout configuration. Ensure that the procurement documentation matches the GBPC-W-4 package style. Cross-reference the manufacturer part number with official Comchip Technology records to validate authenticity before integration into production lines.
Selection Notes
Select this component when a 50 A continuous current and 800 V blocking voltage are required in a through-hole bridge rectifier format. Compare the 1.1 V forward voltage against system loss requirements. Verify that the PCB layout supports the 28.8 mm x 28.8 mm footprint and that thermal management strategies accommodate the 150°C operating limit.
Part Context
This part belongs to the KBPC series of high-current bridge rectifiers from Comchip Technology. It shares the GBPC-W-4 package form factor with other variants in the family, differing primarily in voltage ratings and current capacities. The series is designed for industrial and commercial applications requiring reliable single-phase rectification.
Replacement Considerations
Direct substitutes include the GBPC5008-G, which shares identical electrical specifications and package dimensions. Other compatible replacements must match the 50 A current rating, 800 V reverse voltage, and through-hole solder pin termination style.
