KBL406G

Overview

The Taiwan Semiconductor KBL406G is a single-phase silicon bridge rectifier rated for a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 4 A. It utilizes the KBL plastic package with four pins for through-hole mounting. The device supports a peak non-repetitive forward surge current of 150 A at 8.3 ms. Electrical characteristics include a maximum DC reverse current of 10 µA and a peak forward voltage of 1.1 V at 4 A. The operating junction temperature range spans from -55°C to +150°C.

Feature Summary

• Constructed with glass-passivated junctions for enhanced reliability under reverse voltage conditions.
• Utilizes molded plastic technology compliant with UL 94V-0 flammability ratings.
• Designed for high mechanical strength, ensuring stability during high-temperature soldering processes.

Applications

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

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to confirm exact electrical tolerances and packaging variations. Ensure compliance with RoHS directives if required by the target application. Cross-reference the part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 600 V blocking capability is required for 4 A continuous loads. The KBL package offers a compact footprint suitable for PCB mounting where space is limited. Consider thermal management requirements based on the specified junction temperature limits and ambient operating conditions.

Part Context

This component belongs to the KBL4 series of single-phase bridge rectifiers manufactured by Taiwan Semiconductor. The series provides various voltage ratings while maintaining consistent current handling and package dimensions. The KBL406G specifically addresses applications requiring 600 V isolation within a standard through-hole form factor.

Replacement Considerations

Direct substitutes include other manufacturers' KBL406 variants or equivalent 4 A / 600 V bridge rectifiers in the KBL package. Verify pinout compatibility and thermal resistance values when considering alternatives from different suppliers.
