KBL405G T0G

Overview

The KBL405G T0G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes glass passivated junction technology and is housed in a KBL through-hole package with four pins. The device supports a maximum average forward rectified current of 4 A and a peak repetitive reverse voltage of 600 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 4 A, a typical thermal resistance of 2.4 °C/W (junction-to-lead) and 19 °C/W (junction-to-ambient), and a peak non-repetitive forward surge current of 150 A for an 8.3 ms half-sine wave. The operating junction temperature range spans from -55 °C to +150 °C.

Feature Summary

• Glass passivated junction construction for reliable performance
• Halogen-free molding compound compliant with IEC 61249-2-21 definition
• Matte tin plated leads ensuring solderability per JESD22-B102 standard
• UL Recognized File # E-326243 certification

Applications

• Printed circuit board installations requiring compact rectification
• General purpose AC to DC power conversion circuits
• Industrial equipment utilizing resistive or inductive loads

Procurement Notes

Verify the specific ordering suffix 'T0G' against official manufacturer documentation to confirm packaging details and halogen-free status. Ensure compatibility with RoHS Directive 2011/65/EU requirements if applicable to your supply chain. Cross-reference datasheet version G13 for accurate mechanical dimensions and electrical ratings before finalizing procurement specifications.

Selection Notes

Select this component when a 600 V reverse voltage rating and 4 A continuous forward current are required for single-phase applications. Consider the KBL package size for through-hole mounting constraints. Evaluate the thermal resistance values against your heatsinking strategy, as the junction-to-ambient resistance is 19 °C/W without additional cooling measures.

Part Context

This part belongs to the KBL40xG series, which includes variants ranging from 50 V to 1000 V reverse voltage ratings. All members share the same KBL physical footprint and 4 A current capacity, differing primarily in their blocking voltage capabilities. The 'G' suffix indicates compliance with halogen-free standards.

Replacement Considerations

Direct replacements within the same series include KBL404G and KBL406G, provided the voltage requirements align with the application's peak reverse voltage needs. Verify that alternative manufacturers offer equivalent KBL packages and matching electrical parameters such as forward voltage and surge current ratings.
