GBU4K-LV-T

Overview

The GBU4K-LV-T is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current of 2.8 A and a peak reverse voltage of 800 V. The device utilizes a standard GBU plastic case with dimensions of 21.5 x 18.2 x 3.4 mm. It supports a maximum surge current of 135 A and operates within a junction temperature range of -55°C to +150°C. The component is designed for surface-mount applications in power supply circuits.

Feature Summary

• Single-phase bridge rectification using standard silicon technology
• High thermal stability with a maximum junction temperature of 150°C
• Robust surge current handling capability for transient protection
• Compact GBU package design suitable for automated surface-mount assembly

Applications

• General-purpose AC to DC conversion in power supplies
• Battery charging circuits requiring high reverse voltage tolerance
• Industrial control systems with demanding thermal environments
• Consumer electronics adapters and power adapters

Procurement Notes

Verify the specific electrical parameters against the official Diotec Semiconductor datasheet, particularly noting the distinction between the standard GBU4K (4A) and the GBU4K-LV variant (2.8A). Confirm that the LV designation aligns with your circuit's current requirements. Ensure the GBU package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the supplier's authenticity before ordering.

Selection Notes

Select this component when a single-phase rectifier with 800V reverse voltage capability is required. The 2.8A average current rating suits moderate power applications where space efficiency is critical. Consider the GBU package size for board real estate limitations. Evaluate the thermal management needs given the 150°C junction limit. Compare against higher current variants if load demands exceed 2.8A continuously.

Part Context

This part belongs to Diotec Semiconductor's GBU series of single-phase bridge rectifiers. The series offers various voltage ratings from 50V to 1000V. The GBU4K-LV-T represents a specific low-voltage variant within the 800V class, optimized for specific current derating profiles compared to the standard GBU4K model.

Replacement Considerations

Direct substitutes include other 800V, 2.8A-4A single-phase bridge rectifiers in the GBU package. Verify pinout compatibility and thermal resistance characteristics. Cross-reference with generic equivalents ensuring identical peak reverse voltage and average forward current ratings.
