KBP151G C2

Overview

The KBP151G 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 provides a maximum average forward rectified current of 1.5 A and supports a peak forward surge current of 50 A for 8.3 ms half-sine waves. Its maximum repetitive peak reverse voltage is rated at 50 V, with a corresponding maximum RMS voltage of 35 V and DC blocking voltage of 50 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.

Feature Summary

• Glass passivated junctions provide stable electrical characteristics and improved reverse leakage performance.
• Molded plastic construction ensures reliable low-cost assembly suitable for printed circuit board mounting.
• High surge current capability allows the device to withstand transient overload conditions during operation.

Applications

• Adapters and power supplies
• Battery chargers
• General-purpose rectification in electronic circuits

Procurement Notes

Verify that the ordering suffix matches the required packing code, as the C2 designation indicates a specific tube packaging format. Confirm compliance requirements such as RoHS directives and halogen-free status according to IEC 61249-2-21 definitions when sourcing components for regulated environments. Ensure the manufacturer documentation aligns with the specific part number requested to avoid discrepancies in technical specifications or physical dimensions.

Selection Notes

Select this component based on the 50 V reverse voltage rating and 1.5 A continuous current requirement. Consider the thermal resistance values and derating curves if operating near maximum temperature limits. Verify that the through-hole KBP-4 package fits the available PCB footprint and that the lead spacing accommodates the manufacturing process.

Part Context

This component belongs to the KBP15xG series, which includes variants ranging from 50 V to 1000 V reverse voltage ratings. All members share identical mechanical dimensions and current handling capabilities, differing only in their peak reverse voltage specifications. The 'G' suffix denotes halogen-free construction, while the 'C2' suffix specifies the tube packing method used for distribution.

Replacement Considerations

Other devices within the KBP15xG family offer higher voltage ratings but maintain the same form factor. Cross-referencing with generic 1.5 A bridge rectifiers requires verifying pinout compatibility and ensuring equivalent surge current and thermal performance metrics are met for the intended application environment.
