GBU12J-T

Overview

The GBU12J-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 peak repetitive reverse voltage of 600 V and an average forward rectified current of 12 A. The device exhibits a maximum forward voltage drop of 1 V at rated current and supports a non-repetitive peak surge current of 270 A. Operating reliably within a temperature range from -50 °C to +150 °C, it incorporates a low leakage current of 5 µA. The component utilizes solder pin termination and weighs approximately 4.078 g, providing robust performance for general-purpose power supply applications.

Feature Summary

• High thermal stability with an extended operating junction temperature range up to 150 °C
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved energy efficiency
• UL recognized plastic case material classified as UL94V-0

Applications

• General-purpose AC/DC power supplies
• Battery chargers
• Adapters and power bricks
• Industrial control systems

Procurement Notes

Verify the specific suffix 'T' against the official Diotec Semiconductor datasheet to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact electrical ratings required for the target circuit design. Cross-reference with authorized distributors to confirm current availability and lead times. Validate RoHS and REACH compliance status prior to integration into final products.

Selection Notes

Select this component when a 600 V reverse voltage rating is required for mains-connected applications. The 12 A current capacity suits medium-power designs. Compare the 1 V forward voltage against lower-drop alternatives if efficiency is critical. Ensure the GBU-4 through-hole footprint fits the PCB layout constraints. Verify that the 270 A surge rating exceeds the expected inrush currents of the load.

Part Context

The GBU12J-T belongs to the GBU series of single-phase bridge rectifiers from Diotec Semiconductor. This series shares common mechanical dimensions and thermal characteristics across various voltage ratings, such as the GBU12A (100 V), GBU12B (200 V), and GBU12D (400 V). The 'J' suffix specifically denotes the 600 V blocking voltage variant within this standardized family.

Replacement Considerations

Direct substitutes include other GBU12xx series parts from Diotec with matching current ratings but different voltage ratings, provided the system voltage allows. Generic equivalents from other manufacturers must match the 12 A current, 600 V reverse voltage, GBU-4 package, and pinout configuration.
