Overview
The GBU12A-T is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor, designed for through-hole mounting in the GBU-4 package. It features a maximum average forward rectified current of 12 A and a repetitive peak reverse voltage of 50 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and supports a non-repetitive peak forward surge current of 270 A. Operating temperatures range from -50 °C to +150 °C junction temperature, with a typical reverse leakage current of 5 µA.
Feature Summary
- Single-phase bridge configuration utilizing silicon technology
- Through-hole solder pin termination for PCB integration
- High thermal stability supporting elevated junction temperatures
Applications
- General-purpose AC to DC power supply circuits
- Battery charging systems requiring low voltage rectification
- Industrial control power modules
Procurement Notes
Verify the specific suffix 'T' against the official Diotec Semiconductor datasheet to confirm packaging details, as standard bulk quantities may differ. Ensure the component meets required RoHS and REACH compliance standards for the target market. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a 12 A current rating and 50 V reverse voltage are sufficient for the application. Compare the 1.1 V forward voltage drop against efficiency requirements. Verify that the GBU-4 package dimensions fit the mechanical constraints. Consider higher voltage variants like GBU12B or GBU12D if system transients exceed 50 V.
Part Context
This part belongs to the GBU series of plastic bridge rectifiers from Diotec Semiconductor. The series offers various voltage ratings (e.g., GBU12A, GBU12B, GBU12D) sharing the same 12 A current capacity and GBU-4 package form factor. The GBU12A specifically denotes the 50 V variant within this standardized product line.
Replacement Considerations
Direct functional substitutes include other manufacturers' GBU12A equivalents. Verify pinout compatibility and thermal characteristics. Alternative Diotec parts such as GBU12B (100V) or GBU12D (200V) offer higher voltage margins but require circuit validation.
