Overview
The GeneSiC Semiconductor KBPC5004W is a single-phase silicon bridge rectifier designed for high-efficiency power conversion. It features a maximum average forward rectified current (IO) of 50 A and a repetitive peak reverse voltage (VRRM) of 400 V. The device supports a peak forward surge current (IFSM) of 400 A under standard half-sine wave conditions. Electrical characteristics are specified at a case temperature (Tc) of 25 °C, with a typical thermal resistance per leg of 2.5 °C/W. The component operates within a junction temperature range of -55 °C to 150 °C.
Feature Summary
- Utilizes a metal encapsulation case for robust mechanical protection and thermal dissipation.
- Designed for high efficiency in single-phase rectification applications.
- Features a mounting hole configuration compatible with #10 screws for secure installation.
Applications
- General-purpose AC to DC power supply rectification
- Industrial equipment requiring reliable single-phase bridge rectification
- Power supplies operating within the specified voltage and current ratings
Procurement Notes
Verify the specific ordering suffix 'W' against the manufacturer's documentation to confirm package type compatibility. Ensure that procurement specifications match the required electrical parameters, particularly the 400 V reverse voltage rating and 50 A current capacity. Confirm RoHS compliance status through official datasheets or supplier declarations before finalizing orders.
Selection Notes
Select this component when a 50 A continuous current rating and 400 V blocking voltage are required for single-phase applications. Consider the 2.5 °C/W thermal resistance per leg for heat sink design calculations. Verify that the operating environment stays within the -55 °C to 150 °C junction temperature range. Derate current by 20% if used with capacitive loads as per specification guidelines.
Part Context
The KBPC5004W belongs to the KBPC series of single-phase silicon bridge rectifiers manufactured by GeneSiC Semiconductor. This series includes variants ranging from 50 V to 400 V VRRM, all sharing similar mechanical dimensions and thermal characteristics. The 'W' suffix typically denotes a specific package variation within the KBPC-T/W family, distinguished by its terminal configuration and mounting style.
Replacement Considerations
Direct replacements must match the 50 A IO, 400 V VRRM, and KBPC package form factor. Verify pinout compatibility and thermal resistance values. Cross-reference with other manufacturers offering equivalent single-phase bridge rectifiers in the same current and voltage class.
