KBJ2008G-TU

Overview

The KBJ2008G-TU is a single-phase bridge rectifier manufactured by Diodes Incorporated, designed for through-hole mounting in the KBJ package. It features a maximum average forward rectified current of 2.0 A and a repetitive peak reverse voltage of 800 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and supports a non-repetitive peak surge current of 65 A. Operating temperatures range from -55 °C to +150 °C junction temperature. The component utilizes glass passivated die construction to ensure high reliability and low leakage current under high-temperature conditions.

Feature Summary

• Glass passivated die construction provides high case dielectric strength and low reverse leakage current.
• Molded plastic case meets Underwriters Laboratories flammability classification 94V-0.
• Suitable for automatic insertion on printed circuit boards with reliable low-cost construction.

Applications

• General purpose AC to DC conversion in power supply circuits.
• Bridge rectification in consumer electronics and home appliances.
• Adapter and charger input stages requiring compact through-hole solutions.

Procurement Notes

Verify the specific suffix TU against official Diodes Incorporated documentation to confirm tape and reel packaging details, as standard KBJ variants often utilize tube packaging. Ensure the ordering part number matches the exact electrical specifications required for the target application, particularly regarding the 800 V reverse voltage rating and 2.0 A current capacity. Cross-reference datasheet revisions to confirm compliance with RoHS and REACH directives.

Selection Notes

Select this component when an 800 V blocking capability and 2.0 A continuous current are required in a through-hole KBJ footprint. Compare the 1.1 V forward voltage drop against thermal management requirements for the specific enclosure design. Verify that the 65 A surge current rating exceeds the expected inrush currents of the load circuit to prevent device failure during startup or fault conditions.

Part Context

This component belongs to the KBJ series of silicon bridge rectifiers produced by Diodes Incorporated. The series typically offers various voltage ratings from 50 V to 1000 V with current ratings ranging from 2.0 A to higher values. The KBJ package is characterized by its robust molded plastic construction and lead-through-hole termination style, distinguishing it from surface-mount alternatives like the KBP series.

Replacement Considerations

Compatible substitutes include the KBJ2008 from other manufacturers such as Panjit or SECOS, provided they match the 2.0 A current, 800 V voltage, and KBJ mechanical dimensions. Verify pinout compatibility and thermal characteristics before substitution.
