GBU10B

Overview

The GBU10B is a single-phase bridge rectifier manufactured by Diotec Semiconductor, rated for an average forward current of 10 A and a peak repetitive reverse voltage of 200 V. It utilizes silicon technology and features a through-hole installation style with solder pin termination in the GBU-4 package. The device supports a maximum non-repetitive peak forward surge current of 220 A at 60 Hz and operates within a junction temperature range of -50°C to +150°C. Typical thermal resistance values are 18 K/W (junction-to-ambient) and 2.7 K/W (junction-to-case).

Feature Summary

• Robust surge handling capability designed to withstand high transient currents during power-up or fault conditions.
• Low thermal resistance construction facilitates efficient heat dissipation from the junction to the case for reliable operation under load.
• Wide operating temperature range ensures stable performance across demanding industrial and commercial environments.

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems
• Industrial control equipment

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number GBU10B with official Diotec Semiconductor documentation. Confirm that the ordering suffix matches the specific voltage rating required for the application. Ensure compliance with relevant environmental directives such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when a 10 A continuous current rating and 200 V blocking voltage are required for through-hole mounting. Evaluate the thermal management requirements against the specified junction-to-ambient thermal resistance. Ensure the circuit design accommodates the peak surge current limits defined in the datasheet specifications.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 10 A current capacity and standardized GBU package footprint for interchangeability within designs.

Replacement Considerations

Compatible substitutes include other 10 A, 200 V single-phase bridge rectifiers in the GBU-4 package. Verify that alternative components meet the same electrical ratings and physical dimensions to ensure direct replacement without PCB layout modifications.
