KBP157G C2

Overview

The KBP157G C2 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features glass passivation and operates with a maximum average forward rectified current of 1.5 A. The device supports a maximum repetitive peak reverse voltage of 1000 V, corresponding to a maximum RMS voltage of 700 V and a DC blocking voltage of 1000 V. It exhibits a maximum instantaneous forward voltage of 1.1 V at 1.5 A and handles a peak forward surge current of 50 A. Electrical characteristics are defined within an operating junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated structure for improved stability and reliability
• Molded plastic construction utilizing UL flammability classification 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
• Battery charging circuits in consumer electronics

Procurement Notes

Verify the specific ordering suffix 'C2' against the manufacturer's official documentation to confirm the packing code and green compound specifications. Ensure that procurement channels provide traceable datasheets matching Document Number DS_D1311018. Confirm compliance requirements such as halogen-free status and UL recognition file E-326243 align with project specifications before finalizing orders.

Selection Notes

Select this component when a 1000 V reverse voltage rating is required alongside a 1.5 A continuous current capacity. The through-hole KBP-4 package is suitable for applications needing robust mechanical mounting. Consider the thermal resistance values and derating curves if operation exceeds standard ambient temperatures. Verify lead solderability per JESD22-B102 if specific plating finishes are mandated.

Part Context

This part belongs to the KBP15xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, differentiated by the numeric suffix (e.g., 151G to 157G). The KBP157G specifically denotes the 1000 V variant within this inline bridge rectifier family.

Replacement Considerations

Cross-reference with other KBP157G variants from different manufacturers ensuring identical 1.5 A current, 1000 V voltage, and KBP-4 package dimensions. Verify electrical parameters such as forward voltage and leakage current match or exceed original specifications.
