KBPC1508W-G

Overview

The KBPC1508W-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting. It features an average forward current of 15 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a KBPC-W-4 plastic package with solder pin termination. Electrical characteristics include a maximum non-repetitive surge current of 300 A and a maximum DC forward voltage drop of 1.1 V at rated current. The component operates within a junction temperature range from -55 °C to +150 °C, ensuring reliability in demanding power conversion applications.

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 energy efficiency

Applications

• AC-DC power supply units
• Battery chargers
• General-purpose rectification circuits

Procurement Notes

Verify the specific manufacturer designation on the datasheet, as some listings associate this part number with GeneSiC or Navitas due to corporate acquisitions. Confirm RoHS compliance status directly with the supplier documentation before procurement. Ensure the ordering suffix matches the required lead-free specification. Cross-reference the package outline dimensions against your PCB footprint requirements to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 15 A continuous current rating and 800 V blocking voltage are required in a standard through-hole configuration. Compare the 1.1 V forward voltage drop against alternative brands to assess thermal management needs. Verify that the 300 A surge rating exceeds the expected inrush currents of the target application circuit to prevent device failure during startup conditions.

Part Context

This component belongs to the KBPC series of bridge rectifiers, which are widely used in industrial and consumer electronics. The KBPC1508W-G specifically addresses the need for high-voltage rectification in compact through-hole designs. It serves as a standard solution for converting AC input to DC output in medium-power applications requiring reliable performance over a wide temperature range.

Replacement Considerations

Direct substitutes include the GBPC1508W from onsemi, which shares identical electrical ratings and package dimensions. Other compatible alternatives may include parts from Sensitron or Won-Top Electronics, provided they meet the 15 A/800 V specifications and physical form factor constraints.
