KBU2510

Overview

The MDD KBU2510 is a single-phase silicon bridge rectifier in the KBU series, designed for through-hole PCB mounting. It features a molded plastic body with Underwriters Laboratory Flammability Classification 94V-0. The device supports a maximum repetitive peak reverse voltage of 1000 V and an average forward output rectified current of 25 A at Tc=50°C. It withstands a peak forward surge current of 400 A under JEDEC testing conditions. Operating junction temperature ranges from -55°C to +150°C. The component utilizes solder-plated terminals compliant with MIL-STD-750 Method 2026.

Feature Summary

• High forward surge current capability rated at 400 A
• Low reverse leakage current characteristics
• Guaranteed high-temperature soldering resistance up to 260°C for 10 seconds
• Suitable for printed circuit board installation in any mounting position

Applications

• Printed circuit board power supply circuits
• General purpose AC to DC rectification
• Industrial equipment requiring robust thermal performance

Procurement Notes

Verify that the specific order matches the original MDD KBU2510 part number. Confirm compliance with RoHS and RoHS III standards as specified in the documentation. Ensure the packaging quantity aligns with the bulk box configuration of 400 pieces per box. Check terminal solderability against MIL-STD-750 Method 2026 requirements during incoming inspection.

Selection Notes

Select this component when a 1000 V reverse voltage rating and 25 A continuous current are required for through-hole applications. Consider the 400 A surge capacity for circuits with high inrush currents. Verify that the operating environment stays within the -55°C to +150°C junction temperature range. Ensure PCB layout accommodates the KBU package dimensions and lead spacing.

Part Context

The KBU2510 belongs to the KBU series of thru-hole silicon bridge rectifiers manufactured by MDD. This series is characterized by glass-passivated junctions and molded plastic bodies. The component is distinct from surface mount variants and is specifically engineered for standard PCB mounting techniques. It serves as a reliable solution for medium-power rectification tasks in electronic assemblies.

Replacement Considerations

Cross-reference models include KBU2510 from other manufacturers such as Yangzhou Yangjie Electric and Microdiode Semiconductors. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent electrical ratings for voltage, current, and thermal performance.
