KBP154G C2

Overview

The KBP154G C2 is a single-phase glass passivated bridge rectifier manufactured by Taiwan Semiconductor. It provides a maximum average forward rectified current of 1.5 A and supports a maximum repetitive peak reverse voltage of 400 V. The device features a peak forward surge current capability of 50 A for an 8.3 ms half-sine wave. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 1.5 A, with reverse currents specified at 10 μA at 25°C and 500 μA at 125°C. It operates within a junction temperature range of -55°C to +150°C and utilizes a KBP-4 through-hole package.

Feature Summary

• Glass passivated junctions provide reliable low-cost construction utilizing molded plastic technique.
• High surge current capability suitable for demanding power applications.
• Halogen-free molding compound compliant with IEC 61249-2-21 definition.
• Matte tin plated leads are solderable per JESD22-B102 standards.

Applications

• Printed circuit board mounting for general-purpose rectification
• Power supply input stages requiring 400V blocking capability
• Industrial equipment AC-to-DC conversion

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packing code details. Confirm that the component meets RoHS Directive 2011/65/EU requirements and WEEE 2002/96/EC compliance if environmental regulations apply to the assembly process. Ensure the green compound halogen-free designation matches project specifications.

Selection Notes

Select this component when a 1.5 A continuous current rating and 400 V peak reverse voltage are required for single-phase bridge rectification. Consider the thermal resistance values and derating curves for ambient temperature management. Verify that the through-hole KBP-4 package dimensions fit the target PCB layout constraints.

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, sharing identical mechanical and electrical performance profiles except for the reverse voltage specifications. The 'C2' suffix indicates a specific packing configuration within the product line.

Replacement Considerations

Other devices within the KBP15xG family offer different voltage ratings but share the same 1.5 A current capacity and physical footprint. Cross-referencing datasheets for specific voltage requirements is necessary when substituting parts in existing designs.
