GBJ804

Overview

The GBJ804 is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It features an average forward rectified output current of 8.0 A at a case temperature of +110°C and a maximum repetitive peak reverse voltage of 400 V. The device exhibits a maximum forward voltage of 1.0 V at 4.0 A and a non-repetitive peak forward surge current rating of 170 A for an 8.3 ms half-sine wave. Operating temperatures range from -55°C to +150°C, with a typical thermal resistance of 1.6 °C/W per element.

Feature Summary

• Glass passivated die construction ensures high reliability and low reverse leakage current.
• High case dielectric strength rated at 1500 VRMS for enhanced safety isolation.
• Surge overload capability supports up to 170 A peak current for robust transient protection.
• UL listed as a recognized component under file number E95060.

Applications

• Printed circuit board applications requiring through-hole mounting.
• General-purpose AC to DC power supply conversion circuits.
• Industrial equipment utilizing standard recovery bridge rectification.

Procurement Notes

Verify the specific ordering suffix when sourcing components. The official datasheet lists the orderable part number as GBJ804-F. Confirm that the received units match this exact designation to ensure compliance with the manufacturer's specifications and packaging requirements.

Selection Notes

Select this component for designs requiring an 8 A continuous current capacity and a 400 V blocking voltage. Ensure the application allows for adequate heat sinking or airflow to maintain the case temperature within the specified limits during operation.

Part Context

This component belongs to the GBJ8005–GBJ810 series of 8 A standard recovery bridge rectifiers. The series provides various voltage ratings ranging from 50 V to 1000 V while maintaining consistent current handling and physical package dimensions across all variants.

Replacement Considerations

Compatible substitutes include other 8 A, 400 V bridge rectifiers in the GBJ package. Verify that replacement parts meet the same electrical parameters, specifically the 1.0 V forward voltage and 170 A surge current ratings.
