KBL406G T0G

Overview

The KBL406G T0G is a single-phase bridge rectifier from Taiwan Semiconductor, utilizing glass-passivated junctions for enhanced reliability. It operates with a maximum repetitive peak reverse voltage of 600 V and supports a maximum average forward rectified current of 4 A. The device features a peak forward surge current rating of 150 A under an 8.3 ms half-sine-wave condition. Electrical characteristics include a maximum DC reverse current of 10 µA at 25°C and 500 µA at 125°C, alongside a maximum instantaneous forward voltage of 1.1 V at 4 A. The component functions within an operating junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide mechanical strength and meet JESD 201 class 1A standards for whisker testing.
• Halogen-free construction compliant with IEC 61249-2-21 definitions, indicated by the green compound code.
• UL recognized (File # E-326243) with molding compound rated 94V-0 flammability classification.

Applications

• Printed circuit board mounting in general-purpose power supply circuits
• AC to DC conversion stages in industrial equipment
• Adapters and chargers requiring robust bridge rectification

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packing configuration. Confirm that the requested unit matches the halogen-free specification associated with the designated packing code. Cross-reference the date code and factory code markings on the physical component against the marking diagram provided in the datasheet to validate authenticity and traceability.

Selection Notes

Select this component when a 600 V reverse voltage rating and 4 A continuous current capacity are required for through-hole PCB applications. Ensure the thermal management design accounts for the typical junction-to-ambient thermal resistance of 19°C/W without a heatsink. Verify that the application does not exceed the specified peak forward surge current limits during startup or fault conditions.

Part Context

This part belongs to the KBL40xG series of glass passivated bridge rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V while maintaining a consistent 4 A current rating across all variants. The KBL406G specifically addresses the 600 V requirement within this standardized product line.

Replacement Considerations

Compatible substitutes within the same series include KBL405G and KBL407G, which share identical electrical and mechanical specifications but differ in their peak reverse voltage ratings.
