KBP202G C2G

Overview

The KBP202G C2G is a glass passivated single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 2 A and a peak repetitive reverse voltage of 200 V, with a corresponding maximum DC blocking voltage of 200 V and RMS voltage of 140 V. The device exhibits a maximum instantaneous forward voltage of 1.2 V at 2 A and supports a peak forward surge current of 60 A for an 8.3 ms half-sine wave. Operating junction temperature ranges from -55 °C to +150 °C, with a typical thermal resistance (junction-to-lead) of 8 °C/W. The component utilizes a KBP molded plastic case with matte tin-plated leads.

Feature Summary

• Glass passivation provides stable electrical characteristics and protects the junction against mechanical stress.
• Molded plastic construction ensures reliable low-cost assembly suitable for printed circuit board mounting.
• Halogen-free formulation complies with IEC 61249-2-21 definitions for environmental safety.

Applications

• General-purpose AC to DC power supply rectification
• Battery charging circuits
• Adapters and power bricks

Procurement Notes

Verify the specific ordering suffix to confirm packing configuration and material compliance. The 'C2' designation indicates tube packaging with green compound, while 'G' confirms halogen-free status per IEC standards. Cross-reference the manufacturer's latest datasheet version to ensure alignment with RoHS directives and UL recognition file E-326243 requirements before finalizing procurement specifications.

Selection Notes

Select this component when a 2 A continuous current rating and 200 V reverse voltage capability are required for through-hole PCB applications. Ensure the operating environment stays within the specified -55 °C to +150 °C junction temperature range. Consider the 60 A surge current rating for inductive load switching scenarios. Verify that the KBP package dimensions fit the available board space and that the lead spacing matches the target footprint layout.

Part Context

This part belongs to the KBP20xG series, which includes variants ranging from 50 V to 1000 V reverse voltage ratings. All members share identical current handling and physical package characteristics, differing only in their breakdown voltage specifications. The KBP202G specifically targets low-voltage AC line applications requiring robust surge protection and standard rectification performance.

Replacement Considerations

Direct functional substitutes include other manufacturers' KBP202G equivalents or KBP202 variants from different brands. Ensure replacement parts maintain the same 2 A current rating, 200 V reverse voltage, and KBP package outline to guarantee mechanical compatibility without redesigning the PCB footprint.

FAQ

What does the 'G' suffix indicate in the part number?

The 'G' suffix denotes that the molding compound is halogen-free according to the IEC 61249-2-21 definition.

Is the KBP202G C2G suitable for high-frequency switching applications?

No, it is designed as a general-purpose rectifier. High-frequency applications typically require fast-recovery or Schottky diodes due to slower reverse recovery times inherent in standard bridge rectifiers.

What is the maximum non-repetitive surge current rating?

The device can withstand a peak forward surge current of 60 A for an 8.3 ms single half-sine-wave superimposed on rated load.
