GBU810-G

Overview

The Comchip Technology GBU810-G is a single-phase bridge rectifier utilizing glass passivated junction technology. It features an 8.0 A average forward rectified current and a 1000 V maximum repetitive peak reverse voltage. The device employs a GBU-4 surface-mount package with four leads, measuring approximately 21.9 mm in width, 18.6 mm in length, and 4.2 mm in height. Key electrical characteristics include a 1.1 V maximum DC forward voltage at rated current and a 5 µA maximum reverse leakage current. It supports a 200 A surge current overload rating and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide reliable operation and enhanced stability under varying thermal conditions.
• Molded plastic construction utilizes flammability classification 94V-0 for improved safety compliance.
• Designed for printed circuit board mounting with flexible positioning capabilities.

Applications

• General-purpose power supply circuits
• Adapters and chargers
• Industrial control systems

Procurement Notes

Verify the specific manufacturer datasheet revision when sourcing the GBU810-G from Comchip Technology or authorized distributors. Confirm that the component matches the GBU-4 package dimensions and lead configuration required for your PCB layout. Ensure the ordering suffix corresponds to the standard bulk or tape-and-reel packaging options available for this part number.

Selection Notes

Select the GBU810-G for applications requiring high reverse voltage blocking capability combined with moderate current handling in a compact form factor. The 1000 V rating makes it suitable for universal input AC-DC conversion stages. Consider the 1.1 V forward voltage drop when calculating thermal management requirements for the rectification stage.

Part Context

The GBU810-G belongs to the GBU series of glass passivated bridge rectifiers, widely used in consumer and industrial electronics. This series is characterized by its low-profile surface-mount design, which facilitates automated assembly processes. The GBU-4 package variant offers a balance between current capacity and board space efficiency compared to larger through-hole alternatives.

Replacement Considerations

Direct substitutes include the Diodes Incorporated GBU810 and Yangzhou Yangjie Electr GBU810. Verify pinout compatibility and ensure equivalent electrical ratings before substitution.
