KBP310G

Overview

The KBP310G is a single-phase glass passivated bridge rectifier manufactured by SMC Diode Solutions. It features a peak repetitive reverse voltage of 1000 V and an average rectified output current of 3 A at 50°C ambient temperature. The device exhibits a maximum forward voltage drop of 1.1 V at 3 A and a low reverse leakage current of 5 µA at 1000 V. Designed for through-hole mounting in the KBP package, it supports a junction operating temperature range from -55°C to +150°C and withstands a peak forward surge current of 60 A under standard JEDEC testing conditions.

Feature Summary

• Glass passivated die construction ensures stable electrical performance and long-term reliability.
• Molded plastic case meets UL flammability classification 94V-0 for safety compliance.
• Plated terminals are solderable per MIL-STD-202 Method 208 for robust mechanical connections.

Applications

• General purpose AC to DC power supply circuits
• Battery charging systems requiring high reverse voltage tolerance
• Industrial control equipment with resistive or inductive loads

Procurement Notes

Verify the manufacturer marking on the component body matches SMC Diode Solutions branding. Confirm the part number suffix indicates the lead-free RoHS compliant version. Check datasheet revisions for any updates to thermal resistance values. Ensure storage conditions comply with moisture sensitivity level requirements before assembly.

Selection Notes

Select this component when a 1000 V blocking capability is required for single-phase rectification. The 3 A current rating suits moderate power applications where space constraints favor the KBP form factor. Consider the 1.1 V forward voltage drop for efficiency calculations in low-voltage output designs. Verify that the 60 A surge rating exceeds the expected inrush currents in the target circuit.

Part Context

This component belongs to the KBP series of single-phase bridge rectifiers produced by SMC Diode Solutions. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 3 A current capacity. The KBP package provides a standardized footprint for through-hole PCB mounting, facilitating easy integration into existing power supply architectures.

Replacement Considerations

Cross-reference with other manufacturers' KBP310G equivalents such as those from Micro Commercial Components or Formosa MS. Ensure substitute parts maintain identical pinout configurations and thermal characteristics. Verify that alternative sources offer the same glass passivation technology and UL 94V-0 certification.
