GBU8J-E3/51

Overview

The GBU8J-E3/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It features an in-line circuit configuration within a GBU case style, designed for printed circuit board mounting. The component supports a maximum repetitive peak reverse voltage of 600 V and delivers a maximum average forward rectified output current of 8.0 A at a case temperature of 60 °C. It withstands a peak forward surge current of 200 A and exhibits a maximum instantaneous forward voltage drop of 1.0 V at the rated current. The device operates within a junction and storage temperature range of -55 to +150 °C.

Feature Summary

• Glass passivation protects junctions against mechanical stress
• High surge current capability for robust operation
• High case dielectric strength of 1500 V RMS

Applications

• AC/DC bridge full wave rectification
• Switching mode power supplies
• General purpose adapters

Procurement Notes

Verify the specific ordering suffix to confirm the delivery mode and base quantity. The /51 designation indicates a paper tray package with a base quantity of 250 units. Confirm that the E3 suffix aligns with RoHS compliance requirements for the intended manufacturing process. Ensure the procurement documentation matches the exact part number to avoid discrepancies in packaging or material categorization.

Selection Notes

Select this component when a 600 V rating is required for AC/DC conversion applications. The GBU package provides high thermal performance suitable for heatsink mounting or PCB copper pad configurations. Verify that the 8.0 A continuous current rating meets the load requirements under the expected ambient temperature conditions. Consider the 200 A surge capability for circuits experiencing high inrush currents.

Part Context

This component belongs to the GBU8 series of single-phase bridge rectifiers from Vishay. The series includes variants with different voltage ratings, such as 50 V, 100 V, 200 V, 400 V, 800 V, and 1000 V. All variants share the same 8.0 A current rating and GBU mechanical footprint, allowing for standardized design layouts across different voltage requirements.

Replacement Considerations

Other GBU8 series parts with identical current ratings but different voltage ratings may be considered if the system voltage allows. Cross-referencing with other manufacturers offering GBU packages requires verification of thermal resistance and pinout compatibility.
