Overview
The GBU12B-T is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current rating of 12 A and a maximum repetitive peak reverse voltage of 100 V. The device utilizes a GBU-4 plastic package with through-hole solder pin termination, designed for high reliability in power supply applications. Key electrical characteristics include a maximum forward voltage drop of 1 V at the rated current and a low reverse leakage current of 5 µA. The component supports a maximum operating junction temperature of +150 °C and can withstand a non-repetitive peak surge current of 270 A.
Feature Summary
- High thermal stability with a maximum operating temperature of +150 °C
- Robust surge current handling capability for transient protection
- Low forward voltage drop to minimize conduction losses
- UL recognized plastic housing classified as UL94V-0
Applications
- General-purpose AC to DC power supply circuits
- Battery charging systems
- Industrial control power modules
Procurement Notes
Verify the specific ordering suffix against official Diotec Semiconductor documentation to confirm packaging configuration. The suffix typically indicates bulk or tape-and-reel availability. Ensure the requested quantity matches the manufacturer's standard factory pack size to avoid unnecessary handling or repackaging requirements during assembly.
Selection Notes
Select this component when a 12 A continuous current capacity and 100 V blocking voltage are required in a compact through-hole format. The GBU-4 package offers a balance between current handling and board space efficiency. Consider the 1 V forward voltage characteristic for thermal management calculations in enclosed designs.
Part Context
This part belongs to the GBU series of silicon bridge rectifiers from Diotec Semiconductor. The series provides various voltage ratings and current capacities within the same standardized GBU-4 footprint, facilitating design flexibility and inventory simplification for manufacturers producing multiple power supply variants.
Replacement Considerations
Compatible substitutes include other GBU-12A, GBU-12D, or GBU-12G variants from Diotec that share identical mechanical dimensions and electrical ratings. Cross-brand replacements must match the 12 A current, 100 V voltage, and GBU-4 package outline.
