Overview
The KBPC5010W-G is a single-phase silicon bridge rectifier manufactured by Comchip Technology. It features a 50 A average forward current rating and a 1 kV maximum repetitive peak reverse voltage. The device utilizes the KBPC-W-4 through-hole package with solder pin termination. Key electrical parameters include a forward voltage of 1.1 V at 25 A, a reverse leakage current of 10 µA at 1000 V, and a maximum non-repetitive surge current of 500 A. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Glass-passivated junctions for enhanced stability and reliability under varying thermal conditions.
- High surge current capability designed to withstand transient overloads during power-up or fault events.
- Isolated mounting flange allows for direct heat sink attachment without additional insulators.
Applications
- Industrial power supply units requiring high current rectification.
- Battery charging systems for electric vehicles and industrial equipment.
- DC motor drives and variable frequency drive input stages.
Procurement Notes
Verify compliance with RoHS3 directives and REACH regulations before integration. Confirm that the specific manufacturing date code aligns with project requirements, as packaging changes may occur. Ensure the supplier provides valid certificates of conformity for the glass-passivation process and material safety data sheets.
Selection Notes
Select this component when a 50 A continuous current and 1 kV blocking voltage are required in a standard through-hole form factor. Compare the 500 A surge rating against expected inrush currents. Consider the KBPC-W-4 package dimensions for PCB layout clearance and thermal management strategies involving the isolated flange.
Part Context
This part belongs to the KBPC5010 series of high-current bridge rectifiers from Comchip Technology. It shares the same electrical ratings as the KBPC5010G but utilizes the specific KBPC-W-4 package variant. The series is designed for general-purpose applications where robustness and high thermal performance are critical.
Replacement Considerations
Direct substitutes include the GBPC5010-G, which offers identical 50 A and 1 kV ratings but uses a screw-mount GBPC-G package. Verify mechanical fit and terminal compatibility when swapping between the KBPC-W-4 and GBPC-G form factors.
