Insights
Vishay's new MOSFET offers significant efficiency gains with best-in-class specs that strengthen their industrial power management portfolio.
Vishay's new SiEH4800EW 80V MOSFET represents a meaningful advancement in power semiconductor technology. The 0.88 mΩ on-resistance at 10V is 15% lower than competing devices, directly translating to reduced conduction losses and higher system efficiency in high-current applications.
The thermal performance improvements are equally significant - the 0.36 °C/W junction-to-case thermal resistance (RthJC) is 18% better than competitors, allowing for better heat dissipation in compact designs. This enables higher power handling in the same thermal envelope.
What's technically impressive is how Vishay achieved these gains while reducing the footprint by 50% compared to TO-263 packages. The PowerPAK 8x8SW package with bond wireless design minimizes parasitic inductance - a critical factor for high-frequency switching applications that reduces switching losses and EMI.
The implementation of fused lead technology increasing the source PAD solderable area to 3.35 mm² (four times larger than traditional designs) is particularly innovative. This significantly reduces current density at the PCB connection point, addressing electro-migration concerns in high-current industrial applications like motor drives and welding equipment.
The wettable flanks feature enhances manufacturing reliability through better visual inspection capabilities - an underappreciated but important factor for industrial equipment with long service life requirements. The high temperature operation to +175 °C suggests robust performance in harsh industrial environments.
Compared to their previous PowerPAK 8x8L, this new device offers double the current handling capability (608A vs 302A) in a thinner package (1.0mm vs 1.7mm), showing a significant generational improvement in Vishay's semiconductor process technology.
Space-Saving Device Offers Low Max. RthJC of 0.36 °C/W and Wettable Flanks to Improve Thermal Performance and Solderability in Industrial Applications
MALVERN, Pa., May 21, 2025 (GLOBE NEWSWIRE) -- To provide higher efficiency for industrial applications, Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new 80 V TrenchFET® Gen IV n-channel power MOSFET in the PowerPAK® 8x8SW bond wireless (BWL) package with best in class on-resistance. Compared to competing devices in the same footprint, the Vishay Siliconix SiEH4800EW offers 15 % lower on-resistance while reducing RthJC by 18 %.
With on-resistance down to 0.88 mΩ typical at 10 V, the device released today minimizes power losses from conduction to increase efficiency while improving thermal performance with a low maximum RthJC of 0.36 °C/W. With its 8 mm by 8 mm footprint, the space-saving device occupies 50 % less PCB space than MOSFETs in the TO-263 package while offering an ultra low profile of 1 mm.
The SiEH4800EW implements a fused lead to increase the source PAD solderable area to 3.35 mm², which is four times larger than a traditional PIN solder area. This decreases the current density between the MOSFET and PCB, reducing the risk of electro-migration risk and enabling a more robust design. In addition, the device’s wettable flanks enhance solderability while making it easier to visually inspect the reliability of solder joints.
The MOSFET is ideal for synchronous rectification and OR-ing functionality. Typical applications will include motor drive controls, power tools, welding equipment, plasma cutting machines, battery management systems, robotics, and 3D printers. In these applications, the device offers high temperature operation to +175 °C, and its BWL design minimizes parasitic inductance while maximizing current capability.
RoHS-compliant and halogen-free, the MOSFET is 100 % Rg and UIS tested.
