GBUK8G

Bridge Rectifier Overview

The GBUK8G is a single-phase diode bridge rectifier from Diotec Semiconductor, rated for an average forward current of 8 A at a case temperature of 50°C. It features a peak repetitive reverse voltage of 400 V and a maximum non-repetitive surge forward current of 200 A under standard half-sine-wave conditions. The device operates within a junction temperature range of -50°C to +150°C. Electrical characteristics include a typical forward voltage of 1 V at 8 A and a reverse recovery time of approximately 1500 ns. Thermal resistance from junction to case is specified at 3.0 K/W per device.

Bridge Rectifier Feature Summary

• High surge current capability with a peak forward surge rating of 200 A.
• Wide operating temperature range supporting junction temperatures up to 150°C.
• Standard GBU through-hole package design for reliable mounting.

Bridge Rectifier Applications

• General-purpose AC-DC power supply circuits
• Industrial control systems requiring robust rectification
• Consumer electronics power adapters

Bridge Rectifier Procurement Notes

Verify the specific manufacturer datasheet before integration, as specifications may be subject to change without notice. Confirm compliance with RoHS directives and environmental regulations relevant to your region. Ensure that the selected component meets the required reliability standards for commercial or industrial applications. Validate thermal management requirements against the specified junction-to-case thermal resistance.

Bridge Rectifier Selection Notes

Select this component when an 8 A continuous current rating and 400 V blocking voltage are required in a GBU package. Consider the 1500 ns reverse recovery time for switching frequency limitations. Evaluate the thermal resistance of 3.0 K/W for heat dissipation needs. Ensure the application does not exceed the 200 A surge current limit during startup or fault conditions.

Bridge Rectifier Part Context

The GBUK8G belongs to Diotec's Protectifiers® series of single-phase bridge rectifiers. This series is designed for general-purpose rectification in standard commercial and industrial environments. The GBUK8G variant specifically targets applications needing 400 V reverse voltage capability within the GBU form factor.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering GBU-8A-400V specifications. Verify pinout compatibility and physical dimensions match the existing footprint. Check if alternative components meet the same thermal and surge current requirements.
