GBU2510-HF

Overview

The GBU2510-HF is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current power supply applications. It features a peak repetitive reverse voltage of 100 V and an average forward rectified current rating of 25 A. The device utilizes glass-passivated silicon die technology within a GBU-4 through-hole package to ensure robust performance under demanding conditions. Key electrical characteristics include a maximum forward voltage drop of 1 V at 12.5 A and a low reverse leakage current of 5 µA at the rated voltage. The component supports a surge current capability of 250 A and operates reliably across a junction temperature range from -55°C to +150°C.

Feature Summary

• Glass-passivated silicon die construction provides enhanced resistance to voltage transients and long-term reliability.
• High thermal stability allows operation up to a junction temperature of 150°C.
• Low forward voltage drop contributes to improved efficiency in power conversion circuits.

Applications

• AC-to-DC power supply units requiring high current capacity
• Battery chargers and DC power adapters
• Industrial motor control systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm compliance with RoHS3 directives and environmental standards. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revisions to confirm package dimensions and pinout configurations match the intended PCB layout requirements.

Selection Notes

Select this component when a 25 A continuous current rating and 100 V blocking voltage are required in a standard GBU footprint. Evaluate the thermal management strategy to maintain junction temperatures within the specified 150°C limit during peak load operations. Consider the 250 A surge current rating to ensure adequate protection against inrush currents typical in capacitive input filter circuits.

Part Context

This component belongs to the GBU series of bridge rectifiers, which are widely used in general-purpose power electronics. The GBU2510 variant specifically addresses applications needing substantial current handling in a compact through-hole form factor. It serves as a fundamental building block for converting alternating current to direct current in various industrial and consumer electronic devices.

Replacement Considerations

Compatible substitutes include other 25 A, 100 V bridge rectifiers in the GBU-4 package such as the GBU2501 or GBU2510 from different manufacturers, provided pin compatibility and electrical ratings are verified.
