KBU1008

Overview

The GeneSiC Semiconductor KBU1008 is a single-phase silicon bridge rectifier designed for through-hole mounting. It features a molded plastic body with plated, solderable leads. The device supports a maximum average forward rectified current of 10 A and offers a repetitive peak reverse voltage of 800 V. Key electrical parameters include a DC blocking voltage of 800 V, an RMS reverse voltage of 560 V, and a maximum instantaneous forward voltage drop of 1.05 V at 10 A. It withstands a peak forward surge current of 300 A under half-sine wave conditions. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• High forward surge current capability suitable for demanding power applications
• Ideal for printed circuit board mounting with flexible positioning
• Guaranteed high-temperature soldering resistance up to 250°C

Applications

• Printed circuit board assembly for AC-to-DC conversion
• General-purpose rectification in industrial equipment
• Power supply units requiring robust surge handling

Procurement Notes

Verify the manufacturer designation on official documentation, as distributor listings may occasionally attribute this part to Navitas Semiconductor due to corporate acquisitions. Confirm the specific voltage rating suffix matches the required 800 V application. Ensure compliance with RoHS directives if restricted materials are prohibited in the target assembly process.

Selection Notes

Select the KBU1008 when an 800 V reverse voltage rating is required alongside a 10 A continuous current capacity. This model fits within the KBU series family, sharing mechanical dimensions with variants like KBU1006 and KBU1010. Consider derating the current by 20% if the load is capacitive rather than resistive or inductive to ensure reliable operation.

Part Context

The KBU1008 belongs to the KBU series of single-phase bridge rectifiers manufactured by GeneSiC Semiconductor. This series includes adjacent models such as the KBU1006 (600 V) and KBU1010 (1000 V), which share identical physical packaging and thermal characteristics but differ in their voltage blocking capabilities. The series is standardized for general-purpose rectification tasks.

Replacement Considerations

Compatible substitutes within the same package include the KBU1006 for lower voltage applications and the KBU1010 for higher voltage requirements. Other manufacturers offering equivalent KBU-style 10 A bridge rectifiers with 800 V ratings may serve as functional replacements provided pinout and thermal specifications align.
