KBU1002

Overview

The GeneSiC Semiconductor KBU1002 is a single-phase silicon bridge rectifier designed for through-hole mounting. It features a maximum average forward rectified current (IO) of 10 A and a repetitive peak reverse voltage (VRRM) of 200 V. The device supports a peak forward surge current (IFSM) of 500 A under half-sine wave conditions. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.05 V per leg at rated current. The component operates within a junction temperature range of -55 °C to +150 °C and utilizes a molded plastic body with plated, solderable leads.

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 assembly handling

Applications

• General-purpose AC to DC power supply rectification
• Industrial control systems requiring reliable bridge rectification
• Consumer electronics power adapters

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm electrical ratings and mechanical dimensions. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm RoHS compliance status and packaging details directly with authorized distributors or the manufacturer prior to ordering.

Selection Notes

Select the KBU1002 when a 10 A continuous current rating and 200 V reverse voltage blocking capability are required. Consider the 500 A surge current rating for applications with high inrush currents. Verify that the operating environment stays within the specified -55 °C to +150 °C temperature range and that through-hole mounting is feasible for the design.

Part Context

The KBU1002 belongs to the KBU series of single-phase silicon bridge rectifiers from GeneSiC Semiconductor. This series includes variants with different voltage ratings, such as the KBU10005 (50 V), KBU1001 (100 V), and KBU1004 (400 V), all sharing the same 10 A current rating and KBU package form factor.

Replacement Considerations

Direct substitutes within the same series include the KBU1001 (100 V) if lower voltage tolerance is acceptable, or the KBU1004 (400 V) for higher voltage headroom. Cross-manufacturer replacements must match the 10 A IO, 200 V VRRM, KBU package, and pinout configuration.
