KBP304G-BP

Overview

The KBP304G-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a glass passivated chip junction and operates with an average rectified forward current of 3 A. The device supports a peak repetitive reverse voltage of 400 V, with a maximum RMS reverse voltage of 280 V. Electrical characteristics include a typical forward voltage of 1.0 V at 1.5 A and a reverse leakage current of 10 µA at rated voltage and 25°C. The component handles a non-repetitive peak surge current of 80 A for an 8.3 ms half-sine wave. It utilizes the GBP-4 through-hole package.

Feature Summary

• Glass passivated chip junction construction
• Halogen-free "Green" device compliant with environmental standards
• Epoxy material meets UL 94 V-0 flammability rating

Applications

• General purpose AC to DC power supply conversion
• Low voltage DC power supplies
• Battery chargers

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors due to counterfeiting risks. Confirm the "BP" suffix indicates RoHS compliance and lead-free finish. Check for specific packing quantities such as bulk tubes or cartons when placing orders. Ensure the part status remains active for intended designs.

Selection Notes

Select this component for applications requiring 3 A continuous current and 400 V reverse voltage blocking capability. Consider the GBP-4 through-hole package dimensions for PCB layout constraints. Evaluate thermal resistance values if heatsinking is required for high ambient temperatures. Compare surge current ratings against circuit inrush requirements.

Part Context

This part belongs to the KBP30xxG series of 3 Amp bridge rectifiers from Micro Commercial Components. The series covers various voltage ratings from 50 V to 1000 V, sharing identical physical packages and general electrical characteristics except for voltage specifications. The KBP304G specifically targets the 400 V rating within this lineup.

Replacement Considerations

Compatible substitutes include other 3 A, 400 V single-phase bridge rectifiers in the GBP-4 package. Verify pinout compatibility and thermal resistance parameters before substitution. Ensure replacement parts meet the same glass passivation and flammability standards.
