KBP155G C2G

Overview

The KBP155G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features glass passivation and utilizes a molded plastic construction within the KBP-4 through-hole package. The device supports a maximum average forward rectified current of 1.5 A and offers a peak repetitive reverse voltage rating of 600 V. Key electrical specifications include a maximum instantaneous forward voltage of 1.1 V at 1.5 A, a peak forward surge current capability of 50 A, and a maximum DC reverse current of 10 µA at rated voltage. The component operates reliably across a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated structure for improved stability and reliability
• Molded plastic technique ensures low-cost construction with UL flammability classification 94V-0
• High surge current capability suitable for demanding power applications
• Halogen-free composition compliant with IEC 61249-2-21 definitions

Applications

• Printed circuit board assembly for general-purpose power supplies
• Adapters and chargers requiring robust bridge rectification
• Industrial equipment utilizing single-phase AC-to-DC conversion

Procurement Notes

Verify that the ordering suffix includes both 'C2' and 'G'. The 'C2' code indicates tube packing, while the 'G' designation confirms the use of green compound and halogen-free materials. Ensure the specific part number matches the required 600 V reverse voltage rating within the KBP15xG series before procurement.

Selection Notes

Select this component when a 600 V blocking voltage is required for single-phase rectification. The 1.5 A current rating and 50 A surge capacity define its operational limits. Consider the KBP-4 through-hole package dimensions and thermal resistance characteristics for proper heat dissipation in the target design environment.

Part Context

This component belongs to the KBP151G through KBP157G family from Taiwan Semiconductor. The family shares identical mechanical and electrical performance profiles, differentiated solely by the maximum repetitive peak reverse voltage ratings ranging from 50 V to 1000 V. The KBP155G specifically addresses the 600 V requirement within this standardized lineup.

Replacement Considerations

Direct functional replacements within the same manufacturer's portfolio include KBP153G, KBP154G, KBP156G, and KBP157G, provided the voltage ratings meet or exceed the circuit requirements. Cross-manufacturer equivalents must be verified against the KBP-4 footprint and 1.5 A current specifications.
