KBP156G C2G

Overview

The KBP156G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features glass passivation and operates within an ambient temperature range of -55°C to +150°C. The device supports a maximum average forward rectified current of 1.5 A and withstands a peak forward surge current of 50 A for 8.3 ms. Electrical specifications include a maximum repetitive peak reverse voltage of 600 V, a maximum RMS voltage of 420 V, and a maximum DC blocking voltage of 600 V. Typical thermal resistance values are 13°C/W (junction-to-lead) and 40°C/W (junction-to-ambient).

Feature Summary

• Glass passivated junction structure for improved reliability.
• Molded plastic construction utilizing UL flammability classification rating 94V-0.
• Compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards.
• Halogen-free composition according to IEC 61249-2-21 definition.

Applications

• Printed circuit board mounting for general-purpose power supplies.
• Adapters and chargers requiring high surge current capability.
• Industrial equipment operating in demanding environmental conditions.

Procurement Notes

Verify the specific ordering suffix 'C2G' against official datasheets to confirm packing code and green compound specifications. Ensure that procurement documentation explicitly references the Taiwan Semiconductor part number KBP156G C2G to avoid confusion with similar variants in the KBP15xG series. Confirm compliance requirements such as halogen-free status and RoHS directives match project specifications before finalizing orders.

Selection Notes

Select this component when a 600 V reverse voltage rating is required for single-phase bridge rectification applications. The 1.5 A average forward current rating suits moderate power loads. Consider the through-hole KBP-4 package for standard PCB assembly processes. Evaluate thermal management needs based on the specified thermal resistance values if operating near maximum current limits.

Part Context

This component belongs to the KBP15xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, sharing identical mechanical dimensions and electrical characteristics except for the reverse voltage parameters. The 'G' suffix indicates halogen-free material compliance, while 'C2' denotes the specific tube packing configuration.

Replacement Considerations

Cross-reference other manufacturers offering KBP156G equivalents with matching 600 V reverse voltage and 1.5 A forward current ratings. Verify pinout compatibility and physical dimensions of the KBP-4 package. Ensure substitute components meet the same thermal resistance and surge current specifications for direct replacement.
