GBJ810

Overview

The GBJ810 is an 8A standard recovery bridge rectifier manufactured by Diodes Incorporated. It features a maximum repetitive peak reverse voltage of 1000V and a forward current rating of 8.0A at a case temperature of +110°C. The device exhibits a maximum forward voltage drop of 1.0V at 4.0A and a leakage current of 5µA at rated voltage and +25°C, rising to 500µA at +125°C. Non-repetitive peak forward surge current reaches 170A for an 8.3ms half-sine wave. Operating and storage temperatures range from -55°C to +150°C.

Feature Summary

• Glass passivated die construction ensures reliable low-cost performance with high case dielectric strength of 1500VRMS.
• Low reverse leakage current and low forward voltage drop optimize efficiency in power conversion circuits.
• High surge overload rating supports robust operation against transient current spikes up to 170A peak.
• Molded plastic package with UL flammability classification 94V-0 is ideal for printed circuit board applications.

Applications

• General-purpose AC to DC rectification in power supplies
• Battery charging circuits requiring high surge capability
• Industrial control systems operating within wide temperature ranges

Procurement Notes

Verify the specific ordering suffix '-F' when sourcing components, as it denotes the tube packaging configuration containing 15 units per carrier. Confirm RoHS compliance status and lead-free finish specifications directly with the manufacturer or authorized distributors to ensure adherence to environmental directives applicable to your region.

Selection Notes

Select the GBJ810 when a 1000V blocking voltage and 8A continuous current are required for through-hole mounting. Ensure thermal management allows the junction temperature to remain within the specified -55°C to +150°C range. Consider the 1.6°C/W thermal resistance for heatsinking calculations if operating near maximum current ratings.

Part Context

This component belongs to the GBJ8005–GBJ810 series of 8A glass passivated bridge rectifiers. The series offers various reverse voltage options ranging from 50V to 1000V, sharing identical mechanical dimensions and electrical characteristics except for the breakdown voltage rating. All variants utilize the GBJ package format designed for PCB mounting.

Replacement Considerations

Direct substitutes include other 8A, 1000V bridge rectifiers in the GBJ package such as the GBJ810 from different manufacturers. Verify that replacement parts match the 1.0V max forward voltage and 170A surge current ratings to maintain circuit performance integrity.

FAQ

What is the maximum non-repetitive peak forward surge current?

The GBJ810 can withstand a non-repetitive peak forward surge current of 170A for an 8.3ms single half-sine wave superimposed on rated load.

How does leakage current vary with temperature?

Leakage current is specified as a maximum of 5µA at +25°C and increases to a maximum of 500µA at +125°C when tested at the rated voltage.

Is the GBJ810 suitable for automotive applications?

Standard GBJ810 parts are not automatically qualified for automotive use. For applications requiring AEC-Q100/101/104/200 qualification and IATF 16949 manufacturing, customers must contact Diodes Incorporated directly.
