KBP306-BP

Overview

The KBP306-BP is a single-phase silicon bridge rectifier manufactured by Micro Commercial Components (MCC). It provides an average forward current of 3.0A at 55°C and supports a maximum repetitive peak reverse voltage of 600V with a DC blocking voltage of 600V. The device features a maximum RMS voltage of 420V and a peak forward surge current rating of 80A for 8.3ms half-sine pulses. Electrical characteristics include a maximum forward voltage drop of 1.1V per element at 1.0A and a maximum DC reverse current of 10µA at 25°C. The component utilizes a GBP-4 through-hole package with solder pin termination.

Feature Summary

• Glass passivated junction construction ensures high reliability and resistance to voltage transients.
• Molded plastic case material meets UL flammability classification rating 94V-0.
• Designed for ideal mounting on printed circuit boards using through-hole technology.

Applications

• General purpose AC to DC conversion in power supply circuits.
• Bridge rectification in low to medium power electronic equipment.
• DC output stages for adapters and consumer electronics.

Procurement Notes

Verify the specific ordering suffix against official MCC documentation to confirm compliance status, as the datasheet indicates that the 'P' suffix designates RoHS compliance. Ensure procurement channels are authorized distributors to guarantee genuine parts with full traceability and adherence to handling standards. Confirm package dimensions match the GBP-4 specification before integration.

Selection Notes

Select this component when a 600V reverse voltage rating is required for 3A applications. Verify thermal management requirements, as the average forward current derates significantly above 55°C ambient temperature. Compare the 80A surge capability against potential inrush currents in the target circuit to ensure adequate safety margins during startup conditions.

Part Context

This part belongs to the KBP3005 through KBP310 series of 3 Amp bridge rectifiers from Micro Commercial Components. The series covers voltage ratings from 50V to 1000V, sharing identical physical dimensions and electrical current characteristics while varying only in reverse voltage capabilities. The KBP306 specifically targets 600V applications within this standardized form factor.

Replacement Considerations

Cross-reference with other manufacturers offering the KBP306 designation or equivalent 3A/600V bridge rectifiers in the GBP-4 package. Verify that substitute components maintain matching forward voltage drops and surge current ratings to ensure circuit compatibility without redesign.
