Overview
The GBU8K-LV is a low forward voltage single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 8 A and a peak repetitive reverse voltage (VRRM) of 800 V. The typical forward voltage (VF) is 0.87 V at 25°C with an 8 A load. Peak forward surge current (IFSM) ratings are 180 A for 50 Hz half-sine waves and 200 A for 60 Hz half-sine waves. The device operates within a junction temperature range of -50°C to +150°C, with a thermal resistance from junction to case of 3.0 K/W.
Feature Summary
- Low forward voltage design for enhanced power conversion efficiency
- Robust silicon construction suitable for high-temperature environments
- Plastic encapsulation with Underwriters Laboratory flammability classification 94V-0
Applications
- General-purpose AC to DC power supply circuits

Procurement Notes
Verify the specific part number against official manufacturer documentation before procurement. Confirm that the Low Vf variant meets the electrical requirements of the target circuit design. Ensure compliance with relevant safety standards and environmental directives applicable to the intended deployment region.
Selection Notes
Select this component when reduced conduction losses are critical for system efficiency. Evaluate the thermal management strategy based on the specified thermal resistance values. Ensure the operating environment remains within the defined junction temperature limits to maintain long-term reliability and performance stability.
Part Context
This component belongs to the GBU series of single-phase bridge rectifiers produced by Diotec Semiconductor. The series utilizes molded plastic techniques for cost-effective and reliable construction. The GBU8K-LV specifically addresses applications requiring lower forward voltage drops compared to standard variants within the same package footprint.
Replacement Considerations
Substitute only with verified equivalent parts offering matching IFAV, VRRM, and VF characteristics. Verify pinout compatibility and physical dimensions to ensure proper mounting. Confirm that alternative components meet or exceed the required thermal and surge current specifications.
