KBPF205G C0G

Overview

The KBPF205G C0G is a single-phase glass passivated bridge rectifier manufactured by Taiwan Semiconductor. It features a peak average forward current of 2A and a repetitive peak reverse voltage of 600V. The device utilizes a KBFP molded plastic package with four pins for through-hole mounting. Electrical characteristics include a maximum forward voltage of 1.1V at 1A, a typical reverse current of 5µA at rated voltage, and a junction capacitance of 18pF. Thermal resistance from junction to lead is typically 12°C/W. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivation provides reliable low-cost construction utilizing molded plastic technique
• High surge current capability suitable for demanding power applications
• Compliant to RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards

Applications

• General purpose AC/DC bridge full wave rectification
• Switching Mode Power Supplies (SMPS)
• Space constrained appliance applications

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. The datasheet lists the C8G suffix for tube packing; ensure the requested variant matches available supply configurations. Confirm compliance requirements such as halogen-free status per IEC 61249-2-21 if applicable to the design.

Selection Notes

Select this component when a 600V rating is required for general-purpose rectification in space-constrained designs. Ensure the PCB layout accommodates the KBFP package dimensions and thermal dissipation needs. Verify that the 2A continuous current rating meets the circuit load requirements under expected ambient temperatures.

Part Context

This part belongs to the KBPF204G-KBPF207G series from Taiwan Semiconductor. The series offers varying reverse voltage ratings from 400V to 1000V while maintaining a consistent 2A forward current capacity. All variants share identical mechanical dimensions and electrical performance profiles except for their breakdown voltage specifications.

Replacement Considerations

Direct substitutes within the same series include KBPF204G (400V), KBPF206G (800V), and KBPF207G (1000V). Cross-manufacturer replacements must match the 2A current, 600V voltage, KBFP package, and pin configuration.
