Mingjiada Electronics has been supplying and purchasing used Infineon IQE046N08LM5 devices for a long time. This device is specifically optimized for high-power-density DC-DC converter applications in telecommunications and data center servers. Please feel free to contact us for more information.
IQE046N08LM5 Product Overview
The IQE046N08LM5 is an 80V N-channel logic-level power MOSFET from Infineon’s OptiMOS™ 5 series, featuring an innovative PQFN 3.3×3.3 Source-Down package. Offering industry-leading, ultra-low on-resistance (RDS(on)) at 25°C and exceptional thermal performance, this device is an ideal choice for high-power-density switching power supply (SMPS) products, particularly for DC-DC converter applications in telecommunications and data center servers.
IQE046N08LM5 Key Technical Advantages
Revolutionary Source-Down Technology
OptiMOS™ Source-Down utilizes internal silicon flip-chip technology, offering significant advantages over traditional packaging: better thermal performance, higher power density, and greater layout flexibility. This design shortens the chip’s heat dissipation path and reduces thermal resistance, effectively enhancing system reliability.
Ultra-Low On-Resistance
The IQE046N08LM5 features a maximum on-resistance (RDS(on)) of just 4.6 mΩ at VGS = 10 V, representing a reduction of approximately 30% compared to products using similar technologies. Low on-resistance translates to lower conduction losses and reduced heat generation, directly improving power conversion efficiency.
Logic-Level Drive
This device supports logic-level drive, allowing for lower gate drive voltages (compatible with 4.5V drive), which reduces gate charges Qrr and QOSS while simplifying gate driver selection and design.
Optimized Parallel Configuration
Featuring a Center-Gate package design, this device is specifically optimized for parallel operation of multiple MOSFETs, helping to simplify parallel configurations and improve current sharing.
