KBP301G

Overview

The KBP301G is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a peak repetitive reverse voltage of 100 V and an average rectified output current of 3 A at an ambient temperature of 50°C. The forward voltage drop is specified as 1.1 V at the rated current, with a maximum reverse leakage current of 5 µA at 100 V. The device operates within a junction temperature range of -55°C to 150°C and utilizes a KBP plastic package for through-hole mounting.

Feature Summary

• Glass passivated die construction ensures high reliability and stability under varying electrical conditions.
• Plastic material meets UL flammability rating 94V-0 for enhanced safety compliance.
• High surge current capability supports robust performance during transient load events.

Applications

• General purpose half-wave rectification in AC to DC power supplies
• Bridge rectifier circuits for resistive or inductive loads
• Low voltage DC power conversion systems

Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and RoHS compliance, as indicated by the 'G' designation. Confirm the manufacturer source directly from SMC Diode Solutions documentation rather than distributor listings. Ensure the component matches the standard KBP mechanical dimensions for PCB footprint compatibility before finalizing procurement orders.

Selection Notes

Select this component for applications requiring 100 V blocking voltage and 3 A continuous current handling. The KBP package is suitable for through-hole assembly where higher thermal mass is beneficial. Consider derating the current by 20% if the circuit involves capacitive loads to prevent excessive stress on the diode junctions during startup phases.

Part Context

The KBP series represents SMC Diode Solutions' standard glass-passivated bridge rectifiers designed for general-purpose electronics. This model belongs to the KBP30xG family, sharing identical mechanical housing and pinout configurations while differing primarily in voltage ratings. It serves as a foundational discrete semiconductor component for basic power supply architectures.

Replacement Considerations

Compatible substitutes include the HER301G through HER308G series from Micro Commercial Components (MCC) which share the DO-201AD-like bridge form factor and similar electrical characteristics. Other manufacturers offering KBP-formatted bridge rectifiers with matching 100 V and 3 A ratings may also serve as functional replacements provided mechanical tolerances align.
