KBJ404G-BP

Overview

The KBJ404G-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It utilizes glass passivation technology for enhanced reliability and operates within a temperature range of -55°C to +150°C. The device features a KBJ-4 through-hole package with solder pin termination, measuring 25.2 mm in length, 9.7 mm in width, and 19.3 mm in height. Key electrical specifications include a maximum average forward rectified current of 4.0 A, a peak repetitive reverse voltage of 400 V, and a maximum non-repetitive peak forward surge current of 120 A.

Feature Summary

• Glass passivated junctions provide improved stability and long-term reliability under varying thermal conditions.
• Designed for high surge current capability to withstand transient overloads during power-up or fault conditions.
• Utilizes a compact through-hole mounting style suitable for standard PCB layouts requiring robust mechanical anchoring.

Applications

• AC-to-DC conversion circuits in general-purpose power supplies.
• Battery charging systems requiring reliable rectification at moderate currents.
• Industrial control equipment operating in environments with significant thermal fluctuations.

Procurement Notes

Verify the specific suffix 'BP' against the manufacturer's latest datasheet to confirm compliance with current environmental directives such as RoHS and REACH. Ensure that the KBJ-4 package dimensions align with the target PCB footprint, as variations may exist between different manufacturing batches or regional production sites. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when a 4A current rating and 400V reverse voltage are required for through-hole applications. Compare the forward voltage drop and leakage current specifications against alternative bridge rectifiers to ensure compatibility with the system's efficiency targets. Consider the physical dimensions of the KBJ-4 package to verify adequate clearance on the printed circuit board relative to adjacent components.

Part Context

This component belongs to the KBJ series of single-phase bridge rectifiers from Micro Commercial Components. The series is characterized by its use of glass passivation techniques and standardized through-hole packaging options. The KBJ404G-BP specifically denotes the 4A/400V variant within this lineup, sharing common thermal and mechanical characteristics with other members of the family while differing in electrical ratings.

Replacement Considerations

Direct substitutes include the Diodes Incorporated KBJ404G, which shares identical electrical ratings and package dimensions. Verify pinout compatibility and thermal resistance values before implementing any cross-brand replacement to ensure seamless integration into existing designs without requiring layout modifications.
