GBU2506F(HF)

Overview

The GBU2506F(HF) is a single-phase bridge rectifier manufactured by HY Electronic (Cayman) Limited. It features a glass passivated chip junction and operates with a maximum repetitive peak reverse voltage of 600V and an average forward rectified current of 25A. The device supports a peak forward surge current of 350A for an 8.3ms half-sine wave. Electrical characteristics include a peak forward voltage of 1.1V at 12.5A DC and a maximum DC reverse current of 10μA at 25°C. The component utilizes a GBU package, complies with UL flammability classification 94V-0, and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip construction for reliable low-cost performance
• Low forward voltage drop and high surge current capability
• Compliant with UL 94V-0 flammability classification

Applications

• AC/DC bridge full wave rectification in general purpose circuits
• Switching mode power supplies (SMPS)
• Lighting ballasts and adapters

Procurement Notes

Verify the manufacturer designation as HY Electronic (Cayman) Limited on the component body or datasheet header. Confirm the specific ordering suffix HF indicates RoHS compliance. Validate that the GBU package outline matches the required PCB footprint dimensions before finalizing procurement orders.

Selection Notes

Select this component when a 600V blocking voltage and 25A continuous current rating are required for through-hole mounting. Ensure thermal management accounts for the specified thermal resistance values if operating near the maximum case temperature limit. Verify derating requirements for capacitive loads to prevent exceeding the rated forward current limits.

Part Context

This part belongs to the GBU series of low VF glass passivated bridge rectifiers from HY Electronic. The series provides standardized solutions for AC-to-DC conversion applications requiring robust surge handling and compact through-hole packaging suitable for automated assembly processes.

Replacement Considerations

Cross-reference with other manufacturers offering GBU2506 variants. Verify that substitute parts maintain identical pin configurations, voltage ratings, and physical dimensions to ensure compatibility with existing PCB layouts and heatsinking requirements.
