Magnachip Introduces New 80V MXT MV MOSFET with TOLT Package for E-Scooters and LEVs

Magnachip has introduced a new 80V MXT MV MOSFET featuring a TOLT (TO-Leaded Top-Side Cooling) package, which is well-suited for thermally demanding applications such as e-scooters and LEVs. The TOLT package reduces thermal resistance, extends lifespan, and enhances system reliability. Magnachip has begun supplying the new MOSFET to a leading global electric motor manufacturer.

Magnachip Semiconductor Corporation (NYSE: MX) has announced the release of a new 80V MXT MV MOSFET, MDLT080N017RH, featuring a TOLT (TO-Leaded Top-Side Cooling) package. This innovative product is designed to address the thermal management challenges faced by e-scooters and Light Electric Vehicles (LEVs), among other applications [1].

The TOLT-packaged MOSFET represents a significant advancement in thermal management. Unlike conventional TOLL (TO-Leadless) packages that dissipate heat through the bottom, the TOLT package is engineered to release heat directly from the top via a mounted metal heat sink. This innovative structure substantially reduces thermal resistance between the junction and the external environment, making it well-suited for thermally demanding applications [1].

Simulations and tests conducted by Magnachip demonstrated that the new 80V MV TOLT package solution achieved an average 22% reduction in junction temperature compared to using standard TOLL packages. This improvement not only extends an application’s lifespan but also enhances the system reliability. Furthermore, the TOLT package enables compact, lightweight application designs thanks to its high power density and efficient thermal flow that does not compromise current-handling capability and thermal safety margins [1].

Magnachip's CEO, YJ Kim, stated, "This new 80V MXT MV MOSFET, equipped with the TOLT package, is a testament to Magnachip’s advanced capabilities in high-performance and energy-efficient power semiconductors. We remain committed to delivering next-generation solutions that address evolving customer needs to strengthen our position in the global power market" [1].

The new MOSFET, MDLT080N017RH, is rated at 80V and has an RDS(on) of 1.7 mΩ (Max., VGS=10V). It is designed for applications including e-scooters, LEVs, e-bikes, personal mobility devices, high-efficiency DC motor drives, battery management systems, power distribution systems, and more [1].

Magnachip, with about 45 years of operating history, owns a portfolio of approximately 1,000 registered patents and pending applications, and has extensive engineering, design, and manufacturing process expertise. The company provides a broad range of standard products to customers worldwide [1].
