Vishay Intertechnology, Inc. introduced a versatile new 30 V n-channel TrenchFET® Gen V power MOSFET that delivers increased power density and enhanced thermal performance for industrial, computer, consumer, and telecom applications.
Featuring source flip technology in the 3.3 mm by 3.3 mm PowerPAK® 1212-F package, the Vishay Siliconix SiSD5300DN provides best in class on-resistance of 0.71 mΩ at 10 V and on-resistance times gate charge — a critical figure of merit (FOM) for MOSFETs used in switching applications — of 42 mΩ*nC.
Occupying the same footprint as the PowerPAK 1212-8S, the device released today offers 18 % lower on-resistance to increase power density, while its source flip technology reduces thermal resistance by 63 °C/W to 56 °C/W. In addition, the SiSD5300DN’s FOM represents a 35 % improvement over previous-generation devices, which translates into reduced conduction and switching losses to save energy in power conversion applications.
PowerPAK1212-F source flip technology reverses the usual proportions of the ground and source pads, extending the area of the ground pad to provide a more efficient thermal dissipation path and thus promoting cooler operation. At the same time, the PowerPAK 1212-F minimizes the extent of the switching area, which helps to reduce the impact of trace noise.
In the PowerPAK 1212-F package specifically, the source pad dimension increases by a factor of 10, from 0.36 mm2 to 4.13 mm2, enabling a commensurate improvement in thermal performance. The PowerPAK1212-F’s center gate design also simplifies parallelization of multiple devices on a single-layer PCB.
The source flip PowerPAK1212-F package of the SiSD5300DN is especially suitable for applications such as secondary rectification, active clamp battery management systems (BMS), buck and BLDC converters, OR-ing FETs, motor drives, and load switches. Typical end products include welding equipment and power tools; servers, edge devices, supercomputers, and tablets; lawnmowers and cleaning robots; and radio base stations.

The National Science Foundation has given a $300,000 grant to Xiaoqing Song, an assistant professor in the Electrical Engineering and Computer Science Department, to support his research project focused on advancing high density and high-operation-temperature traction inverters. Song’s project explores the integration of gallium oxide packaged power modules to enhance the power density and temperature range of electric vehicles.
Collaborating with the National Renewable Energy Laboratory, the project sets out to innovate power module packaging, establish reliable strategies for gallium oxide power devices and demonstrate the capabilities of a high density, high temperature traction inverter.
“By eliminating technical barriers for gallium oxide device integration, this project will foster the development of next-generation, high density and high-operation-temperature power converters,” Song said.
The traction inverter, responsible for converting stored direct current (DC) power into alternating current (AC) power to drive electric motors, stands to benefit significantly from gallium oxide technology. Song said, “Gallium oxide can make the traction inverter smaller, lighter, more efficient and capable of operating across a wider range of temperatures.
“Gallium oxide has a larger band gap energy compared to conventional silicon and wide band gap semiconductors. It enables high breakdown electrical strength, low intrinsic carrier concentration and correspondingly high operation temperatures,” Song said.
One challenge addressed in the project is the low thermal conductivity of gallium oxide, which hinders efficient heat removal. Song outlines the plan to develop advanced power module packaging techniques that enable low thermal resistance, low parasitic inductances and high-temperature operation capability.
“National Renewable Energy Laboratory (NREL) has significant experience in power module simulation, fabrication and characterization, as well as world-class experimental and lab capabilities for evaluating and designing efficient and reliable power electronics systems. The PI will collaborate with them to design and develop a gallium oxide-based high density and operation-temperature traction inverter for automotive applications. This project will help establish a long-term partnership with NREL that can catalyze further research and development of ultra-wide bandgap power semiconductor devices,” Song said.
Song shared that the collaboration with the National Renewable Energy Laboratory aims to design and develop a gallium oxide-based high density and high-operation-temperature traction inverter for automotive applications, fostering a long-term partnership that can drive further research in ultra-wide bandgap power semiconductor devices.
“Other applications include power grids, data centers, renewable energy, space and defense, etc.,” Song added.
The success of the project, he believes, will provide valuable insights into gallium oxide device modeling, packaging, gate driving, protection and application in power converters. These advancements are expected to catalyze progress in transport electrification and the deployment of gallium oxide technology in challenging environments.
“The research achievements and experiences gained in the fellowship will sustain and promote the PI’s future multi-disciplinary research activities in semiconductor devices, multiphysics analysis, power module packaging and high performance power electronics. Other broader impacts also include the education and development of the next generation workforce in STEM (science, technology, engineering and math), the encouragement of more women and underrepresented minorities in electrical engineering, especially in the area of wide and ultra-wide bandgap semiconductor devices, power module packaging and power electronics with hands-on lab experiences,” Song said.
