LKK47-06C5

FET, MOSFET Arrays Overview

The LKK47-06C5 is a dual CoolMOS power MOSFET manufactured by IXYS. It features two N-channel transistors integrated into a single ISOPLUS264-5 package. The device supports a drain-source breakdown voltage of 600V and a continuous drain current of 47A. Key electrical parameters include an on-resistance of 45 mOhms, a gate charge of 190 nC, and a maximum power dissipation of 278W to 480W depending on thermal conditions. Operating temperatures range from -55°C to +150°C.

FET, MOSFET Arrays Feature Summary

• Dual CoolMOS technology integrating two N-channel MOSFETs
• High-voltage capability with 600V drain-source breakdown
• Robust thermal management via ISOPLUS264-5 package design

FET, MOSFET Arrays Applications

• High-frequency switching power supplies
• Motor control applications requiring high current handling
• Industrial inverter circuits

FET, MOSFET Arrays Procurement Notes

Verify the specific datasheet version for accurate thermal resistance values, as power dissipation ratings vary by mounting condition. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as legacy records may indicate varying environmental compliance levels. Ensure the ISOPLUS264-5 footprint matches the target PCB layout before ordering.

FET, MOSFET Arrays Selection Notes

Select this component for designs requiring high voltage isolation and significant current capacity in a compact form factor. The dual configuration allows for bridge or half-bridge topologies without separate component matching. Evaluate thermal requirements carefully, as the 45 mOhm on-resistance generates heat under full load. Consider the 190 nC gate charge for driver selection to ensure adequate switching speed.

FET, MOSFET Arrays Part Context

This part belongs to IXYS's CoolMOS family, known for optimized superjunction technology. The ISOPLUS264-5 package provides enhanced thermal performance compared to standard TO-247 variants. It serves as a discrete solution for medium-power electronics where space constraints and efficiency are critical design drivers.

FET, MOSFET Arrays Replacement Considerations

Direct substitutes must match the 600V/47A rating and ISOPLUS264-5 package. Verify pinout compatibility and thermal characteristics. Cross-reference with other dual CoolMOS devices from IXYS or equivalent manufacturers offering similar Rds(on) and Qg specifications.
