KBJ2510G

Overview

The GeneSiC Semiconductor KBJ2510G is a single-phase glass-passivated silicon bridge rectifier designed for through-hole mounting on printed circuit boards. It features a maximum average forward rectified current of 25 A and a repetitive peak reverse voltage of 1000 V. The device exhibits a maximum instantaneous forward voltage of 1.05 V at 25 A and a maximum reverse current of 10 μA at rated DC blocking voltage. It supports a peak forward surge current of 350 A under standard test conditions. The component operates within an ambient temperature range of -55°C to +150°C and utilizes molded plastic construction classified as UL 94V-0 flammability.

Feature Summary

• Glass passivation provides reliable junction protection
• Molded plastic construction with UL 94V-0 flammability rating
• Low forward voltage drop for improved efficiency
• High surge current capability for robust operation

Applications

• Printed circuit board power supply designs
• AC to DC conversion circuits
• General purpose rectification in industrial equipment

Procurement Notes

Verify the manufacturer designation carefully, as the KBJ series is widely produced by multiple semiconductor companies including Micro Commercial Components and Taiwan Semiconductor. Confirm that the specific part number matches the required electrical ratings and package dimensions before procurement. Ensure the supplier provides official datasheets to validate the glass-passivated construction and thermal characteristics.

Selection Notes

Select this component when a 25 A current rating and 1000 V reverse voltage are required for PCB-mounted applications. Consider the 1.05 V forward voltage drop for thermal management calculations. Verify that the operating environment stays within the specified -55°C to +150°C range. Derate the current by 20% if the load is capacitive to ensure reliable performance.

Part Context

The KBJ2510G belongs to the KBJ series of single-phase bridge rectifiers from GeneSiC Semiconductor. This series includes variants with different voltage ratings such as KBJ2506G (600 V) and KBJ2508G (800 V), all sharing the same 25 A current capacity and physical package. The series is characterized by its glass-passivated silicon construction and suitability for automated PCB assembly processes.

Replacement Considerations

Direct replacements include the KBJ2510G from other manufacturers like Micro Commercial Components or Taiwan Semiconductor, provided they meet the identical 25 A and 1000 V specifications. Ensure the replacement maintains the same KBJ package footprint and terminal configuration for mechanical compatibility.
