KBJ25005G

Overview

The KBJ25005G is a single-phase glass-passivated silicon bridge rectifier manufactured by GeneSiC Semiconductor. It features a maximum average forward rectified current of 25 A at an ambient temperature of 25 °C and a peak forward surge current of 350 A under an 8.3 ms single sine-wave condition. The device has a repetitive peak reverse voltage (VRRM) of 50 V, with a corresponding RMS reverse voltage of 35 V and DC blocking voltage of 50 V. The maximum instantaneous forward voltage per leg is 1.05 V when tested at a forward current of 12.5 A. Maximum reverse current is specified as 10 µA at rated DC blocking voltage per leg. The operating junction temperature range extends from -55 °C to 125 °C.

Procurement Notes

Verify the manufacturer designation matches GeneSiC Semiconductor specifications. Confirm the part number suffix corresponds to the 50 V rating variant within the KBJ25005G through KBJ2504G series. Ensure documentation aligns with the October 2018 datasheet revision for accurate electrical parameters and package dimensions.

Selection Notes

Select this component for applications requiring a 25 A continuous current capacity with a 50 V reverse voltage rating. Consider the 1.05 V forward voltage drop for thermal management calculations. Verify that the PCB layout accommodates the specific terminal configuration and spacing defined in the KBJ package outline.

Part Context

This component belongs to the KBJ series of single-phase bridge rectifiers produced by GeneSiC Semiconductor. The series offers various voltage ratings ranging from 50 V to 400 V while maintaining a consistent 25 A current capability and standardized KBJ package footprint for design interchangeability.

Replacement Considerations

Cross-reference with other manufacturers offering the KBJ package format. Ensure substitute parts maintain the 25 A current rating and 50 V minimum reverse voltage withstand capability. Verify pinout compatibility and physical dimensions match the original design constraints.
