KBJ15L06-TU

Overview

The KBJ15L06-TU is a single-phase bridge rectifier manufactured by Diodes Incorporated, designed for medium to high power applications. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified output current of 15 A at a case temperature of +125°C. The device utilizes glass passivated die construction to ensure reliable low-cost performance. Key electrical characteristics include a maximum forward voltage drop of 0.9 V at 7.5 A and a maximum leakage current of 10 µA at 25°C. It supports a peak forward surge current of 200 A and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated die construction provides enhanced reliability and protection against external voltage stresses.
• Low-forward voltage drop design minimizes conduction losses and improves overall system efficiency.
• High case dielectric strength ensures robust insulation and safety in demanding electrical environments.
• Molded plastic technique with UL flammability classification 94V-0 offers durable mechanical packaging.

Applications

• Printed circuit board mounting for general-purpose rectification
• Industrial power supply circuits requiring high reliability
• AC to DC conversion stages in medium power equipment

Procurement Notes

Verify the specific ordering suffix '-TU' corresponds to the tube carrier packaging containing 20 pieces per unit when sourcing components. Confirm that the requested part matches the exact manufacturer designation to ensure compatibility with existing bill of materials and assembly processes. Cross-reference the date code marking format to validate production recency and storage conditions upon receipt.

Selection Notes

Select this component for designs requiring a 600 V blocking capability with a 15 A continuous current rating. Ensure thermal management strategies account for the specified thermal resistance values, particularly if operating without a heatsink where ambient derating curves apply. Verify that the through-hole KBJ package dimensions fit the available PCB real estate and mounting constraints.

Part Context

This device belongs to the KBJ series of low VF bridge rectifiers from Diodes Incorporated. The series is characterized by its ability to handle significant forward currents while maintaining low voltage drops. The KBJ15L06 variant specifically targets applications needing 600 V reverse voltage support, distinguishing it from lower or higher voltage ratings within the same physical footprint family.

Replacement Considerations

Direct substitutes must match the 15 A current rating, 600 V reverse voltage, and KBJ-4 through-hole package. Verify that alternative manufacturers offer equivalent forward voltage and leakage current specifications to maintain circuit performance integrity without redesigning thermal or layout parameters.

FAQ

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

The maximum non-repetitive peak forward surge current is 200 A for an 8.3 ms single half sine wave at a junction temperature of +25°C.

How does the average forward current change with case temperature?

The average forward current is rated at 15 A at a case temperature of +125°C. Derating curves indicate that the allowable current decreases as the case temperature rises above this point.

Is the device compliant with environmental directives?

Yes, the device features lead-free finish and is RoHS compliant. It is also halogen and antimony free, meeting 'Green' device definitions.
