KBU601G

Overview

The KBU601G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features glass passivated junctions and utilizes the KBU-4 through-hole package. The device supports an average forward current of 6 A with a maximum repetitive peak reverse voltage of 50 V. Key electrical parameters include a typical reverse leakage current below 0.1 μA, a maximum non-repetitive peak forward surge current of 200 A, and a forward voltage drop of approximately 1.1 V at rated current. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide stable performance and reliable long-term operation under varying thermal conditions.
• High case dielectric strength ensures robust isolation and safety in high-voltage applications.
• Designed for direct mounting on printed circuit boards, facilitating efficient assembly processes.

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm compliance with RoHS Directive 2011/65/EU and WEEE 2002/96/EC requirements. Ensure halogen-free status aligns with IEC 61249-2-21 definitions when specified. Validate UL Recognized File # E-326243 certification for safety standards adherence.

Selection Notes

Select this component for applications requiring 6 A continuous current handling and low reverse leakage. The KBU-4 package suits through-hole PCB designs. Verify that the 50 V reverse voltage rating meets circuit peak inverse voltage demands. Consider the 200 A surge capability for inrush current protection scenarios.

Part Context

The KBU601G belongs to the KBU series of glass passivated bridge rectifiers from Taiwan Semiconductor. This series includes variants such as KBU601G through KBU607G, differentiated primarily by their peak reverse voltage ratings. The KBU601G specifically offers the lowest voltage rating in this sequence, suitable for low-voltage AC conversion tasks.

Replacement Considerations

Direct substitutes within the same series include KBU602G, KBU603G, KBU604G, KBU605G, KBU606G, and KBU607G, provided the higher voltage ratings do not conflict with design constraints. Cross-manufacturer replacements require matching 6 A current, KBU-4 package, and equivalent electrical characteristics.
