KBP308-BP

Overview

The KBP308-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward rectified current of 3.0A at 55°C and a maximum recurrent peak reverse voltage of 800V. The device has a maximum RMS voltage of 560V and a DC blocking voltage of 800V. 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 supports a peak forward surge current of 80A for 8.3ms half-sine waves and operates within a junction temperature range of -55°C to +125°C.

Feature Summary

• Glass passivated junction construction provides mechanical strength and meets environmental sensitivity standards.
• Molded plastic case with UL flammability classification rating 94V-0.
• Suitable for automatic insertion into printed circuit boards.

Applications

• General purpose rectification in AC to DC power supply circuits.
• Bridge rectifier applications in consumer electronics.
• Industrial control systems requiring standard voltage ratings.

Procurement Notes

Verify the authenticity of the KBP308-BP by purchasing only from MCC or authorized distributors to ensure traceability and quality. Confirm that the ordering suffix matches the required compliance specifications, as the BP designation indicates specific packaging and RoHS status. Check for updated datasheets regarding lead-free finish exemptions and handling storage standards before procurement.

Selection Notes

Select the KBP308-BP when an 800V peak reverse voltage rating is required for single-phase bridge rectification. Ensure the application current does not exceed the 3.0A average forward rectified current limit at the specified ambient temperature. Consider the thermal derating curve if operating temperatures exceed 55°C. Verify that the through-hole package dimensions fit the target PCB layout constraints.

Part Context

The KBP308-BP belongs to the KBP series of single-phase bridge rectifiers from Micro Commercial Components. This series offers various voltage ratings ranging from 50V to 1000V while maintaining a consistent 3.0A current capability. The KBP package is designed for through-hole mounting on printed circuit boards, providing a compact solution for general-purpose rectification tasks in electronic equipment.

Replacement Considerations

The datasheet explicitly states that the KBP3005 through KBP310 series is not recommended for new designs. It recommends using the KBP3005G-BP through KBP310G-BP series as replacements. These newer variants likely incorporate updated compliance features such as enhanced RoHS adherence.
