KBJ3010

Overview

The KBJ3010 is a single-phase bridge rectifier manufactured by Diodes Incorporated, designed for through-hole mounting in the KBJ-4 package. It features an average forward current rating of 30 A and a maximum repetitive peak reverse voltage of 1000 V. The device exhibits a typical forward voltage drop of 1.05 V at 17.5 A and supports a maximum surge current of 350 A. Operating temperatures range from -55°C to +150°C junction temperature, with low reverse leakage current specified at 10 µA under rated voltage conditions.

Feature Summary

• High-voltage capability suitable for demanding power supply applications
• Robust thermal performance with extended operating temperature range
• Standardized KBJ package facilitates automated assembly processes

Applications

• AC-DC power supply circuits
• Battery chargers
• General-purpose rectification in industrial equipment

Procurement Notes

Verify component authenticity against official Diodes Incorporated datasheets before integration. Confirm package markings match the KBJ3010 designation to avoid substitution errors. Ensure storage conditions comply with moisture sensitivity levels specified in the manufacturer's handling guidelines. Cross-reference ordering codes with authorized distributors to guarantee traceability.

Selection Notes

Select this component when 1000 V blocking voltage and 30 A continuous current are required in a standard through-hole bridge configuration. Compare thermal resistance values against PCB copper area constraints to ensure adequate heat dissipation. Evaluate forward voltage characteristics against system efficiency targets. Verify that the KBJ-4 footprint aligns with existing board layout requirements.

Part Context

The KBJ3010 belongs to the KBJ series of single-phase bridge rectifiers from Diodes Incorporated. This series includes variants with different voltage ratings such as KBJ3006 (600 V) and KBJ3008 (800 V), sharing identical current ratings and physical dimensions. The KBJ family is widely used in medium-power applications requiring reliable rectification in compact through-hole packages.

Replacement Considerations

Direct substitutes include KBJ3008 for lower voltage applications or KBJ3510 for higher current capacity. Ensure pinout compatibility and thermal management requirements remain consistent when evaluating alternative part numbers within the same manufacturer's portfolio.
