KBP305G C2

Overview

The KBP305G C2 is a glass passivated single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It provides a maximum repetitive peak reverse voltage of 600 V and supports a maximum average forward rectified current of 3 A. The device features a molded plastic body with matte tin-plated leads, suitable for printed circuit board mounting. Electrical characteristics include a typical junction capacitance of 215 pF per leg at 1 MHz and a maximum instantaneous forward voltage of 1.1 V at 3 A. Operating temperatures range from -55 °C to +150 °C for both junction and storage conditions.

Feature Summary

• Glass passivation protects the junctions against mechanical stress and ensures long-term reliability.
• High surge current capability allows the component to withstand transient overloads during operation.
• Halogen-free molding compound meets environmental directives including RoHS and WEEE compliance.

Applications

• Printed circuit board assembly for AC-DC power conversion
• General-purpose rectification in electronic equipment
• Power supply input stages requiring high dielectric strength

Procurement Notes

Verify the specific ordering suffix 'C2' against the manufacturer's official documentation to confirm packing code details. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the marking diagram and package dimensions provided in the datasheet to validate physical specifications upon receipt.

Selection Notes

Select this component when a 600 V blocking voltage and 3 A continuous current rating are required for single-phase rectification. Consider the thermal resistance values and derating curves if operating near maximum temperature limits. Verify compatibility with lead-free soldering processes due to the matte tin plating and halogen-free material composition.

Part Context

This part belongs to the KBP30xG series of single-phase bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, sharing identical mechanical dimensions and electrical performance profiles except for the reverse voltage specification. The 'G' suffix indicates a halogen-free green compound variant within the standard KBP package family.

Replacement Considerations

Direct substitutes must match the 600 V reverse voltage, 3 A forward current, and KBP package outline. Verify that alternative bridge rectifiers meet the same thermal resistance and surge current requirements to ensure equivalent circuit performance without redesigning the PCB footprint.
