KBU402G

Overview

The KBU402G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes silicon planar technology and features a molded plastic encapsulation within the KBU package. The device provides an average forward rectified current of 4 A at a case temperature of 130°C. Its maximum repetitive peak reverse voltage is rated at 200 V, with a corresponding non-repetitive peak surge forward current capability of 150 A. The component supports a wide operating junction temperature range from -55°C to +175°C.

Feature Summary

• High thermal performance enabled by a junction temperature rating up to 175°C
• Robust surge overload protection for handling transient current spikes
• Molded plastic construction designed for mechanical stability

Applications

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

Procurement Notes

Verify the manufacturer marking on the component body to confirm it reads Taiwan Semiconductor Corporation. Ensure the package type matches the standard KBU outline dimensions. Cross-reference the datasheet revision date with your procurement requirements to ensure compliance with current specifications.

Selection Notes

Select this component when a 4 A current rating and 200 V blocking voltage are required. The KBU package offers higher current capacity compared to smaller bridge rectifiers. Verify that the application environment supports the specified operating temperature range for reliable long-term operation.

Part Context

This part belongs to the KBU series of bridge rectifiers, which are characterized by high current capabilities and robust packaging. The suffix '402' indicates the specific voltage and current ratings within this product family. It serves as a standard solution for medium-power rectification applications requiring high reliability.

Replacement Considerations

Direct replacements must match the 4 A current rating, 200 V reverse voltage, and KBU package footprint. Verify pinout compatibility before substitution. Other manufacturers producing equivalent KBU-series parts may serve as alternatives if electrical parameters align.
