KBP156G C2

Overview

The KBP156G C2 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. Its maximum repetitive peak reverse voltage is rated at 800 V, with a corresponding maximum RMS voltage of 560 V. The component utilizes a KBP-4 through-hole package, measuring approximately 15.24 mm in length, 3.9 mm in width, and 11.68 mm in height. Typical thermal resistance values are 13°C/W for junction-to-lead and 40°C/W for junction-to-air.

Feature Summary

• Glass passivated construction ensures stable electrical characteristics and long-term reliability under varying environmental conditions.
• Molded plastic technique provides reliable low-cost construction with UL flammability classification rating 94V-0.
• Compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards, supporting environmentally conscious manufacturing.

Applications

• Printed circuit board assembly for general-purpose power supply circuits
• AC to DC conversion stages in consumer electronics
• Industrial control systems requiring robust bridge rectification

Procurement Notes

Verify the ordering suffix 'C2' corresponds to the green compound packing code as specified in the official datasheet. Confirm that the 'G' designation indicates compliance with halogen-free requirements per IEC 61249-2-21 definition. Ensure procurement matches the specific voltage rating of 800 VRRM for the KBP156G variant within the KBP15xG series.

Selection Notes

Select this component when an 800 V peak reverse voltage rating is required for single-phase bridge rectification applications. The 1.5 A average forward current capability suits moderate power loads. Consider the KBP-4 through-hole package for standard PCB mounting. Verify thermal management requirements against the specified thermal resistance values if operating near maximum current limits.

Part Context

This part belongs to the KBP151G through KBP157G series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series shares identical mechanical dimensions and current ratings, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50 V to 1000 V. The KBP156G specifically addresses applications requiring 800 V blocking capability.

Replacement Considerations

Direct substitutes must match the 800 V reverse voltage, 1.5 A current rating, and KBP-4 package. Verify pinout compatibility and thermal resistance specifications before substitution.
