KBU1001

Overview

The GeneSiC Semiconductor KBU1001 is a single-phase silicon bridge rectifier designed for through-hole mounting. It features a maximum average forward rectified current of 10 A and a repetitive peak reverse voltage of 100 V. The device exhibits a maximum instantaneous forward voltage drop of 1.05 V per leg at rated conditions and supports a peak forward surge current of 300 A. Operating temperatures range from -55°C to +150°C, with storage capabilities within the same limits. The component utilizes a molded plastic body classified as UL 94V-0 flammability rated.

Feature Summary

• High forward surge current capability for robust transient handling
• Ideal for printed circuit board integration via through-hole technology
• Not ESD sensitive for simplified handling procedures

Applications

• General-purpose AC to DC rectification in power supplies
• Industrial control systems requiring high temperature stability
• Consumer electronics utilizing standard bridge configurations

Procurement Notes

Verify manufacturer attribution carefully, as distributor listings may display Navitas Semiconductor or GeneSiC branding interchangeably due to corporate acquisitions. Confirm the specific datasheet version matches the required electrical parameters, particularly the 100 V rating. Ensure ordering suffixes align with package type requirements before finalizing procurement orders.

Selection Notes

Select this component when a 10 A continuous current rating and 100 V blocking voltage are required for through-hole applications. Consider the 1.05 V forward voltage drop for thermal management calculations. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature range for reliable performance.

Part Context

The KBU1001 belongs to the KBU series of single-phase silicon bridge rectifiers, which includes variants ranging from 50 V to 400 V reverse voltage ratings. This family shares common mechanical dimensions and thermal characteristics, allowing for design flexibility across different voltage requirements while maintaining consistent footprint compatibility.

Replacement Considerations

Direct substitutes include other KBU-series parts like KBU1002 or KBU1004 if higher voltage ratings are acceptable. Cross-brand replacements must match the 10 A current, 100 V reverse voltage, and KBU package outline to ensure physical and electrical compatibility.
