GBJ808-F

Overview

The GBJ808-F is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It provides 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 800 V. The device features a low forward voltage drop of 1.0 V maximum at 4.0 A and a leakage current of 5 µA at rated voltage. It withstands non-repetitive peak forward surge currents up to 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 stable electrical characteristics and long-term reliability under varying conditions.
• High case dielectric strength of 1500 VRMS provides robust isolation between internal components and external mounting surfaces.
• Surge overload rating accommodates transient current spikes up to 170 A without compromising device integrity.
• Molded plastic package meets UL flammability classification 94V-0 for enhanced safety in printed circuit board applications.

Applications

• General-purpose AC-to-DC power supply circuits requiring high voltage blocking capability.
• Industrial equipment power stages operating within extreme ambient temperature ranges.
• Automotive electronics systems utilizing through-hole mounting configurations.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the component matches the required voltage and current ratings for your application. Check for compliance with relevant environmental directives such as RoHS 3. Ensure proper handling procedures are followed during storage and installation to maintain device performance.

Selection Notes

Select this component when designing circuits that require an 800 V reverse voltage rating combined with an 8 A continuous current capacity. Evaluate the thermal management requirements based on the specified junction-to-case thermal resistance. Consider the physical dimensions of the GBJ package to ensure compatibility with the intended PCB layout and mounting constraints.

Part Context

This part belongs to the GBJ8005–GBJ810 series of standard recovery bridge rectifiers. All members share identical mechanical and thermal specifications while differing primarily in their maximum repetitive peak reverse voltage ratings. The series utilizes a standardized GBJ through-hole package suitable for automated assembly processes.

Replacement Considerations

Direct replacements must match the 800 V peak reverse voltage, 8 A average forward current, and GBJ package outline. Verify that alternative bridge rectifiers meet the same 1.0 V forward voltage maximum and 170 A surge current rating to ensure equivalent circuit performance.
