MDmesh V super-junction MOSFET from ST for consumer and industrial electronics

STMicroelectronics has introduced the first MDmesh V Super-Junction MOSFET which enables efficiency of power circuitry in equipment such as white goods, televisions, PCs, telecom, and server switched-mode power supplies. ST says the new TO247-4 4-lead package provides a direct source connection used only for switching control, whereas conventional packages provide one connection for both switching and power. The extra lead increases switching efficiency, which reduces energy losses and allows higher-frequency operation for more compact power supplies. ST co-developed the package with Infineon, which is also introducing its own new Super-Junction devices, providing second-source flexibility for users. “The TO247-4 is highly cost-effective and requires only minimal modification of the PCB layout when replacing a standard TO-247 device, which simplifies adoption in power systems,” commented Maurizio Giudice, Marketing Director, Power Transistor Division, STMicroelectronics. “Our new MDmesh devices using this package will enable better environmental performance of end equipment by improving energy efficiency in active modes.” ST explains: The TO247-4 package features an innovative internal construction implementing a Kelvin connection to the source. This connection bypasses the common source inductance of the main power connection, enabling up to 60% of switching losses to...
