South Korea-based Magnachip Semiconductor has released its new 80 V MXT MV MOSFET, MDLT080N017RH, featuring a TO-Leaded Top-Side Cooling (TOLT) package for thermal management and power efficiency in motor control systems for e-scooters and light EVs.
The company has begun supplying the MOSFET to a leading global electric motor manufacturer.
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 reduces thermal resistance between the junction and the external environment, making it well-suited for thermally demanding applications, according to the company.
Simulations and testing demonstrated that the TOLT package achieved an average 22% reduction in junction temperature compared to using standard TOLL packages. This extends an application’s lifespan and enhances system reliability. 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.
“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,” said YJ Kim, CEO of Magnachip. “We remain committed to delivering next-generation solutions that address evolving customer needs to strengthen our position in the global power market.”
