GBJ804-F

Overview

The GBJ804-F 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 supports 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. Electrical characteristics include a maximum leakage current of 5 µA at rated voltage and +25°C, rising to 500 µA at +125°C. The component utilizes a GBJ through-hole package with molded plastic construction.

Feature Summary

• Glass passivated die construction ensures low reverse leakage current and high reliability.
• High case dielectric strength of 1500 VRMS provides robust insulation capabilities.
• Surge overload rating accommodates peak currents up to 170 A for transient protection.
• UL listed under Recognized Component Index File Number E95060 for safety compliance.

Applications

• Printed circuit board applications requiring compact bridge rectification
• General purpose AC to DC conversion in power supplies
• Industrial equipment utilizing standard recovery diode technology

Procurement Notes

Verify the specific ordering suffix '-F' corresponds to the tube packing quantity of 15 units as documented in the manufacturer's ordering information. Confirm that the RoHS compliant lead-free finish meets the environmental requirements of the target assembly process. Ensure the procurement channel is authorized to guarantee product authenticity and adherence to standard terms of sale.

Selection Notes

Select this component when a 400 V blocking capability and 8 A continuous current are required within a GBJ form factor. Evaluate thermal management needs based on the 1.6 °C/W junction-to-case thermal resistance per element. Verify that the operating temperature range of -55°C to +150°C aligns with the system's ambient conditions and heat dissipation strategy.

Part Context

This part belongs to the GBJ8005–GBJ810 series of 8 A standard recovery bridge rectifiers from Diodes Incorporated. The series covers voltage ratings from 50 V to 1000 V, sharing identical mechanical dimensions and electrical performance profiles except for the breakdown voltage specifications. The GBJ804-F specifically addresses the 400 V segment of this standardized product line.

Replacement Considerations

Cross-reference other manufacturers offering GBJ-4 packages with 8 A current and 400 V reverse voltage ratings. Verify compatibility regarding forward voltage drop, leakage current limits, and physical mounting hole dimensions to ensure direct substitution without PCB redesign.
