KBL406-G

Overview

The Comchip Technology KBL406-G is a single-phase bridge rectifier utilizing silicon epitaxial planar chip technology. It features a GBU-4 through-hole package with solder pin termination, measuring 22.2 mm in length, 19.1 mm in height, and 3.53 mm in width. The device supports a maximum average forward current of 4 A and a peak repetitive reverse voltage of 600 V. Key electrical parameters include a maximum forward voltage of 1.1 V, a reverse leakage current of 10 uA, and a non-repetitive peak forward surge current of 150 A. It operates within a temperature range of -55 C to +150 C.

Feature Summary

• Utilizes silicon epitaxial planar chip construction for reliable performance.
• Features glass passivated chip junctions to ensure stability under varying conditions.
• Designed with low profile packaging to optimize board space efficiency.

Applications

• General purpose power supply circuits
• AC to DC conversion systems
• Battery charging applications

Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce components with identical model numbers. Confirm RoHS compliance status directly from the supplier's documentation. Ensure the GBU-4 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a 4 A current rating and 600 V reverse voltage capability. Consider the GBU-4 through-hole package for manual assembly or high-vibration environments. Evaluate thermal management needs based on the 1.1 V forward voltage drop at full load to ensure proper heat dissipation.

Part Context

This component belongs to the KBL series of bridge rectifiers manufactured by Comchip Technology. It shares the same physical package and general specifications as other variants in the series, differing primarily in reverse voltage ratings. The GBU-4 package is standard for this class of through-hole rectifiers.

Replacement Considerations

Compatible substitutes include the KBL406 from other manufacturers such as ETC or Won-Top Electronics. Verify that replacement parts maintain the same 4 A current rating, 600 V reverse voltage, and GBU-4 package dimensions to ensure mechanical and electrical compatibility.
