2KBP04M

Overview

The 2KBP04M is a general-purpose bridge rectifier manufactured by onsemi. It features a single-phase full-wave configuration with a maximum average forward rectified current of 2 A and a repetitive peak reverse voltage rating of 400 V. The device utilizes glass-passivated junctions for enhanced reliability and surge overload protection. Electrical characteristics include a maximum RMS bridge voltage of 560 V, a DC blocking voltage of 400 V, and a non-repetitive peak forward surge current capability of 70 A at 60 Hz. The unit operates within a junction temperature range of -55 °C to +175 °C and is housed in a KBP package.

Feature Summary

• Glass-passivated junctions provide high reliability and resistance to surge overload conditions.
• High forward current capability rated at 2 A for continuous operation.
• Low forward voltage drop contributes to improved system efficiency.
• Compliant with international standards including UL, CSA, and CQC certifications.

Applications

• AC to DC power supply circuits
• General-purpose rectification in electronic equipment
• Bridging applications requiring robust surge protection

Procurement Notes

Verify the component marking against official datasheet specifications to confirm authenticity. Ensure the package type matches the required PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm the voltage rating aligns with the specific circuit requirements before integration.

Selection Notes

Select this component when a 2 A current rating and 400 V reverse voltage are required for AC-DC conversion. Consider the thermal management capabilities of the KBP package for the intended operating environment. Evaluate the forward voltage drop impact on overall system efficiency compared to alternative rectifier technologies.

Part Context

This part belongs to the 2KBP series of surface-mount bridge rectifiers from onsemi. The series offers various voltage ratings to suit different input AC line requirements while maintaining a consistent 2 A current capacity. It serves as a standard solution for compact power supply designs.

Replacement Considerations

Direct substitutes must match the 2 A current rating, 400 V reverse voltage, and KBP package outline. Verify that alternative manufacturers offer equivalent glass-passivated junction technology and similar thermal characteristics to ensure compatibility.
