KBU6M

Overview

The onsemi KBU6M is a single-phase bridge rectifier in the KBU series, rated for a maximum repetitive reverse voltage of 1000 V and an average forward current of 6.0 A at 65°C ambient temperature. It features a peak non-repetitive forward surge current capability of 250 A and a maximum forward voltage drop of 1.0 V per bridge at 6.0 A. The device operates within a junction temperature range of -55°C to +150°C and utilizes a plastic KBU case with four solder pin terminals.

Feature Summary

High surge current capability for handling transient loads
Reliable construction technique suitable for printed circuit boards
High case dielectric strength of 1500 V RMS

Applications

General purpose AC to DC conversion circuits
Power supply designs requiring high reverse voltage blocking
Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the manufacturer origin carefully, as the KBU6M part number was originally developed by Fairchild Semiconductor and is now distributed by onsemi. Confirm that the specific batch meets RoHS compliance standards if required by your assembly process. Ensure the ordering suffix matches the lead plating specifications needed for your soldering method.

Selection Notes

Select the KBU6M when a 1000 V reverse voltage rating is necessary for the application. Compare thermal resistance values against other bridge rectifiers if heat dissipation is a primary constraint. Ensure the PCB footprint accommodates the KBU package dimensions and lead spacing requirements for reliable mounting.

Part Context

The KBU6M belongs to the broader KBU6A through KBU6M family of bridge rectifiers. This series shares identical electrical characteristics regarding current ratings and thermal performance, differing only in their maximum repetitive reverse voltage ratings. The KBU6M represents the highest voltage variant within this specific standard lineup.
