KBJ2501G

Overview

The GeneSiC Semiconductor KBJ2501G is a single-phase glass-passivated silicon bridge rectifier designed for printed circuit board mounting. It features a KBJ package with a maximum average forward rectified current of 25 A at 25 °C and a peak forward surge current of 350 A. The device supports a repetitive peak reverse voltage of 100 V, an RMS reverse voltage of 70 V, and a DC blocking voltage of 100 V. It exhibits a maximum instantaneous forward voltage per leg of 1.05 V at 12.5 A and a maximum reverse current of 500 μA at rated DC blocking voltage per leg. Operating temperatures range from -55 °C to 125 °C.

Feature Summary

• Glass passivation provides stable electrical characteristics and high reliability under varying conditions.
• Molded plastic construction utilizes UL flammability classification 94V-0 material for safety.
• Low forward voltage drop design enhances efficiency while maintaining high current capability.

Applications

• Printed circuit board mounted power supply circuits
• General purpose AC to DC conversion applications
• Industrial equipment requiring reliable single-phase rectification

Procurement Notes

Verify the specific manufacturer designation on the component marking, as branding may vary between GeneSiC Semiconductor and Navitas Semiconductor due to corporate acquisitions. Confirm that the ordering suffix 'G' corresponds to the standard lead-free configuration without additional functional changes. Ensure the procurement documentation explicitly references the KBJ package dimensions and terminal configuration to guarantee mechanical compatibility during integration.

Selection Notes

Select this component when a 25 A continuous current rating and 100 V reverse voltage are required for PCB-mounted applications. Consider the 350 A surge capability for inrush protection scenarios. Evaluate thermal management requirements, noting the specified operating temperature limits and the need for current derating if capacitive loads are present. Compare physical dimensions against available board space constraints.

Part Context

This component belongs to the KBJ25005G through KBJ2504G series, which offers various voltage ratings within the same 25 A current framework. The KBJ package provides a compact form factor suitable for dense PCB layouts. This series represents a standard solution for general-purpose rectification tasks where cost-effectiveness and moderate performance are prioritized over specialized high-frequency or high-voltage requirements.

Replacement Considerations

Direct substitutes include other KBJ-series bridge rectifiers with matching 25 A and 100 V ratings. Verify pinout compatibility and physical dimensions before substitution. Cross-reference datasheets for equivalent forward voltage and surge current specifications to ensure circuit performance remains unaffected by the replacement part.
