KBPC1004W-G

Overview

The KBPC1004W-G is a single-phase bridge rectifier manufactured by Comchip Technology. It features an average forward current rating of 10 A and a peak repetitive reverse voltage of 400 V. The device utilizes a KBPC-W-4 package with solder pin termination for through-hole mounting. Key electrical parameters include a maximum forward voltage drop of 1.1 V at rated current, a surge current capability of 300 A, and a maximum non-repetitive reverse leakage current of 5 uA. The component operates within a temperature range from -55 °C to +150 °C junction temperature.

Feature Summary

• High thermal stability supporting operation up to 150 °C junction temperature
• Robust surge current handling capability for transient protection
• Low forward voltage drop design for improved efficiency
• Through-hole construction with solder pin termination

Applications

• AC-DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status as per manufacturer documentation. Confirm the package variant matches the KBPC-W-4 footprint requirements for your PCB layout. Ensure the 400 V reverse voltage rating meets the peak inverse voltage demands of your AC input source. Check datasheet limits for thermal derating if operating near the maximum junction temperature.

Selection Notes

Select this component when a 10 A continuous current and 400 V blocking voltage are required in a standard bridge configuration. Compare against the KBPC1010-G if a higher 1 kV rating is needed, or the KBPC5010W-G for significantly higher current capacity. Ensure the through-hole mounting style aligns with assembly capabilities. Verify that the 1.1 V forward voltage drop is acceptable for your system's power loss budget.

Part Context

This part belongs to the KBPC series of single-phase bridge rectifiers from Comchip Technology. The 'W' suffix typically denotes a specific lead-free or enhanced packaging variant within the KBPC family. It shares the same physical dimensions as other KBPC-W devices but differs in electrical ratings compared to lower-current counterparts like the KBPC1000 series.

Replacement Considerations

Direct substitutes must match the 10 A / 400 V specification and KBPC-W-4 package. Cross-reference with other manufacturers offering equivalent single-phase bridges in this form factor. Verify pinout compatibility and thermal characteristics before substitution.
