KBJ1008G-TU

Overview

The KBJ1008G-TU is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It features an 800V maximum repetitive peak reverse voltage (VRRM) and supports a 10A average rectified output current at a case temperature of +110°C. The device utilizes glass passivated die construction within a KBJ through-hole package, ensuring low reverse leakage current. Electrical characteristics include a maximum forward voltage of 1.1V at 5.0A and a peak forward surge current rating of 170A for an 8.3ms half-sine wave. The component operates across a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated die construction provides reliable low-cost performance with high case dielectric strength.
• Molded plastic technique ensures UL flammability classification rating of 94V-0.
• Lead-free finish and RoHS compliant design suitable for printed circuit board applications.

Applications

• General purpose AC to DC conversion in power supplies
• Bridge rectification in industrial control systems
• Power adapters and battery chargers

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the tube packaging quantity matches project requirements. Ensure compliance with applicable environmental directives such as RoHS 2 and RoHS 3. Validate that the component meets all necessary safety certifications for the intended end-use application.

Selection Notes

Select this component when an 800V blocking voltage is required for single-phase bridge rectification. Evaluate thermal management needs based on the 10A current rating and the specified derating curve. Consider the KBJ package dimensions for PCB layout constraints. Verify that the operating temperature range aligns with the system's environmental conditions.

Part Context

This part belongs to the KBJ series of standard recovery bridge rectifiers from Diodes Incorporated. The series includes variants with different voltage ratings, specifically 600V, 800V, and 1000V options. All variants share similar mechanical and electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage capabilities.

Replacement Considerations

Direct replacements must match the 800V VRRM, 10A IF(AV), and KBJ package outline. Verify that alternative components meet the same forward voltage and leakage current specifications. Ensure any substitute maintains equivalent thermal resistance and surge current ratings for safe operation.
