KBP204G C2G

Overview

The KBP204G C2G is a glass-passivated bridge rectifier from the KBP series manufactured by Taiwan Semiconductor. It provides a maximum repetitive peak reverse voltage of 400 V and supports a maximum average forward rectified current of 2 A at 25°C. The device features a peak forward surge current capability of 60 A for an 8.3 ms half-sine wave. Electrical characteristics include a maximum instantaneous forward voltage of 1.2 V at 2 A and a maximum DC reverse current of 500 μA at 125°C. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivation protects the junctions against mechanical stress
• Utilizes molded plastic technique for reliable low-cost construction
• Compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards
• Halogen-free according to IEC 61249-2-21 definition

Applications

• Printed circuit board assembly for general-purpose rectification
• Power supply units requiring 400V reverse blocking capability
• Industrial equipment operating within specified thermal limits

Procurement Notes

Verify the ordering suffix 'C2G' corresponds to the green compound variant and tube packing configuration as documented in the datasheet. Confirm that the specific lot meets UL Recognized File # E-326243 requirements if safety certification is mandatory for the end application. Ensure compatibility with JESD22-B102 solderability standards for matte tin plated leads during assembly processes.

Selection Notes

Select this component when a 400 V reverse voltage rating and 2 A continuous forward current are required for PCB-mounted applications. Consider the 60 A surge current rating for circuits experiencing transient load spikes. Verify that the operating environment stays within the -55°C to +150°C junction temperature range. Evaluate the 1.2 V forward voltage drop for efficiency calculations in low-voltage output stages.

Part Context

This part belongs to the KBP201G through KBP207G series of glass-passivated bridge rectifiers. The series offers varying voltage ratings from 50 V to 1000 V while maintaining a consistent 2 A current capacity and identical physical package dimensions. The KBP204G specifically addresses mid-range voltage applications within this standardized family, sharing common thermal and mechanical characteristics with its siblings.

Replacement Considerations

Direct substitutes must match the 400 V reverse voltage, 2 A forward current, and KBP package outline. Verify equivalent glass passivation technology and thermal resistance values. Ensure replacement components meet the same UL recognition and halogen-free specifications if regulatory compliance is required.
