KBP310GS-BP

Overview

The KBP310GS-BP is a single-phase glass-passivated bridge rectifier manufactured by Micro Commercial Components. It features an average forward current rating of 3.0 A and supports peak repetitive reverse voltages ranging from 50 V to 1000 V. The device utilizes a KBP surface-mount package designed for printed circuit board mounting. Key electrical characteristics include a maximum non-repetitive peak surge current of 60 A at 8.3 ms single half-sine-wave, a maximum RMS isolation voltage of 4000 V, and a maximum DC blocking leakage current of 5 µA at rated DC voltage. Operating temperatures range from -55 °C to +150 °C junction temperature.

Feature Summary

• Glass passivation provides mechanical strength and meets UL flammability classification 94V-0
• Surge overload capability rated at 60 amperes peak
• Suitable for automated assembly on printed circuit boards

Applications

• General-purpose AC-to-DC conversion in power supplies
• Battery charging circuits
• Adapter applications requiring compact surface-mount solutions

Procurement Notes

Verify the specific voltage code suffix (e.g., 05, 08, 10) corresponding to the required Peak Repetitive Reverse Voltage (VRRM) level, as the base part number covers the 50V to 1000V range. Confirm RoHS compliance status and packaging quantity with the authorized distributor or manufacturer representative prior to ordering.

Selection Notes

Select this component when a 3.0 A current rating and surface-mount footprint are required for single-phase rectification. Ensure the chosen voltage variant exceeds the maximum peak inverse voltage present in the application circuit. Consider thermal management requirements given the high operating junction temperature limit of +150 °C.

Part Context

This component belongs to the KBP series of glass-passivated bridge rectifiers from Micro Commercial Components. The 'S' suffix typically denotes the surface-mount KBP package style, while 'BP' indicates Halogen-free/RoHS compliant construction. It serves as a surface-mount alternative to through-hole bridge rectifiers in space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements include the KBP310G from other manufacturers such as Formosa MS or Gulf Semiconductor. Verify that substitute parts maintain identical current ratings, voltage ratings, and package dimensions before implementation.
