GBU10A-T

Overview

The GBU10A-T is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor, designed for general-purpose power conversion applications. It features an average forward rectified current of 10 A and a maximum repetitive peak reverse voltage of 50 V. The device utilizes a plastic case with UL classification 94V-0 and is housed in the GBU-4 through-hole package. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current and a non-repetitive peak forward surge current capability of 250 A. It operates within a junction temperature range of -55 °C to +175 °C and meets RoHS compliance standards.

Feature Summary

• High thermal stability with extended operating junction temperature up to 175 °C
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved efficiency
• Plastic encapsulate with UL 94V-0 flammability rating

Applications

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

Procurement Notes

Verify the specific ordering code against manufacturer documentation to confirm tape-and-reel packaging versus bulk quantities. Ensure the component meets required regulatory standards such as RoHS and REACH for the target market. Cross-reference the suffix 'T' with official Diotec Semiconductor datasheets to confirm packaging specifications before procurement.

Selection Notes

Select this component when a 10 A current rating and 50 V reverse voltage are required in a through-hole GBU package. Consider the 1.1 V forward voltage drop for thermal management calculations. Verify that the 250 A surge current rating aligns with the circuit's inrush requirements. Ensure the PCB layout accommodates the GBU-4 footprint dimensions.

Part Context

The GBU10A belongs to Diotec Semiconductor's GBU series of silicon bridge rectifiers. This series offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 10 A current capacity. The GBU10A specifically targets low-voltage, high-current applications requiring reliable performance in compact through-hole designs.

Replacement Considerations

Compatible alternatives include the GBU10B (100 V), GBU10D (200 V), or GBU10G (400 V) if higher voltage ratings are acceptable. Other manufacturers offering equivalent GBU-10A packages should be verified for matching current, voltage, and thermal specifications.
