Overview
The KBPC5004W-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features an average forward current of 50 A and a repetitive peak reverse voltage of 400 V. The device utilizes a KBPC-W-4 package with screw mount installation style and through-hole termination. Key electrical parameters include a maximum forward voltage of 1.1 V at rated current and a surge current capability of 500 A. The component operates within a temperature range of -55 °C to +150 °C, with a typical reverse leakage current of 10 µA.
Feature Summary
- Glass passivated die construction for enhanced reliability and low reverse leakage current.
- Electrically isolated epoxy case designed for maximum heat dissipation.
- Mechanical design supports through-hole mounting with internally mounted metal heat sink.
Applications
- AC to DC power supply circuits requiring 50 A capacity.
- Battery charging systems operating at 400 V reverse voltage.
- Industrial motor control rectification stages.
Procurement Notes
Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required thermal and mechanical constraints. Confirm RoHS compliance status directly from the supplier documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when a 50 A continuous current rating and 400 V blocking voltage are required in a screw-mountable bridge configuration. Ensure the PCB layout accommodates the KBPC-W-4 footprint and provides adequate clearance for the terminal spacing defined in the official mechanical drawings.
Part Context
This part belongs to the KBPC50 series of glass-passivated bridge rectifiers from Comchip Technology. It shares the standard KBPC-W-4 housing form factor with other variants in the family, differing primarily in voltage ratings such as the 50V (KBPC50005W-G) or 1kV (KBPC5010W-G) models found in public catalogs.
Replacement Considerations
Publicly confirmed substitute part numbers for the KBPC5004W-G were not identified in the provided reference material. Cross-referencing with generic 50A 400V bridge rectifiers requires independent verification of pinout and thermal characteristics.
