KBP104G C2

Overview

The KBP104G C2 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features glass passivated junctions and a molded plastic body with matte tin-plated leads for through-hole mounting. The device provides a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 400 V. Key electrical parameters include a maximum instantaneous forward voltage of 1.0 V at 1 A, a peak forward surge current of 30 A, and a maximum DC reverse current of 500 μA at 125°C. The component operates within a junction temperature range of -55°C to +150°C.

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 compound compliant with IEC 61249-2-21 definition

Applications

• Printed circuit board assembly in general-purpose power supplies
• Offline flyback converter input stages
• Resistive or inductive load rectification

Procurement Notes

Verify the specific ordering suffix 'C2' against the manufacturer's official documentation to confirm packing code details. Ensure compliance requirements such as RoHS Directive 2011/65/EU and WEEE 2002/96/EC are explicitly stated for the exact part number variant being procured. Cross-reference the green compound halogen-free status with the latest datasheet revision.

Selection Notes

Select this component when a 1 A average forward current and 400 V reverse voltage rating are required for through-hole PCB mounting. Consider the thermal resistance values and derating curves if operation near the maximum junction temperature of 150°C is anticipated. Verify that the 30 A surge current capability meets the transient requirements of the target circuit design.

Part Context

This component belongs to the KBP10xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, sharing identical mechanical dimensions and package styles. The KBP104G specifically addresses the 400 V requirement within this standardized inline bridge rectifier family.

Replacement Considerations

Direct substitutes within the same series include KBP101G, KBP102G, KBP103G, KBP105G, KBP106G, and KBP107G, provided the voltage rating matches the application needs. Other manufacturers offering equivalent KBP-style bridge rectifiers should be evaluated based on matching electrical characteristics and mechanical footprint compatibility.
