KBL604G

Overview

The KBL604G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes a glass-passivated junction design and is housed in a KBL through-hole package with four pins. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 6 A at 25°C. It features a typical non-repetitive peak forward surge current capability of 175 A. Electrical characteristics include a maximum RMS isolation voltage of 3,000 V and a low leakage current. The component operates within a temperature range from -55°C to +150°C.

Feature Summary

• Glass-passivated junction construction for enhanced reliability
• High case dielectric strength suitable for PCB mounting
• Low leakage current performance under reverse bias conditions

Applications

• General-purpose AC-to-DC power supply circuits
• Battery charging systems
• Industrial control equipment power stages

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm halogen-free status and packaging configuration. Ensure that the procurement documentation explicitly references the KBL604G part number to distinguish it from other variants within the KBL series. Confirm RoHS compliance requirements match the project specifications before finalizing orders.

Selection Notes

Select this component when a 6 A continuous current rating and 400 V blocking voltage are required in a standard through-hole form factor. Evaluate thermal management needs based on the 6 A rating and ambient operating temperatures up to 150°C. Compare physical dimensions of the KBL package against available board space constraints during the design phase.

Part Context

This component belongs to the KBL series of bridge rectifiers produced by Taiwan Semiconductor. The series is characterized by its robust mechanical design and suitability for general electronic applications requiring reliable rectification in compact through-hole packages.

Replacement Considerations

Cross-reference with other KBL series parts such as KBL601G or KBL605G if voltage ratings differ. Verify pinout compatibility and thermal resistance values before substituting with components from different manufacturers.
