MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has announced the release of the SiEH4800EW, an 80 V TrenchFET® Gen IV n-channel power MOSFET designed to maximize efficiency and thermal performance for industrial uses. Packaged in the space-saving PowerPAK® 8x8SW bond wireless (BWL) package, this innovative device features best-in-class on-resistance and a range of design enhancements.
With an on-resistance as low as 0.88 mΩ typical at 10 V, the SiEH4800EW minimizes power losses, making it an ideal solution for efficiency-conscious applications. The device also boasts a low maximum thermal resistance (RthJC) of 0.36 °C/W, enabling superior thermal performance. Its compact 8 mm by 8 mm footprint occupies 50% less printed circuit board (PCB) space compared to TO-263 packaged MOSFETs, while maintaining an ultra-slim profile of just 1 mm.
“By offering 15% lower on-resistance and an 18% improvement in thermal resistance over competing devices in the same footprint, Vishay’s SiEH4800EW sets a new benchmark in power MOSFET performance,” said Vishay’s spokesperson.
The MOSFET incorporates a fused lead design that expands the source PAD solderable area to 3.35 mm², quadrupling the size of conventional PIN solder areas. This reduces current density between the MOSFET and PCB, lowering the risk of electro-migration and enhancing reliability. Additional features, such as wettable flanks, improve solderability while simplifying visual inspection of solder joints to ensure robust designs.
Capable of operating at high temperatures up to +175 °C, the SiEH4800EW is ideally suited for applications such as motor drive controls, welding equipment, robotics, battery management systems, and more. Its design also reduces parasitic inductance, ensuring maximum current capability in high-performance environments.
RoHS-compliant and halogen-free, the SiEH4800EW further strengthens Vishay’s position as a leader in power electronics. Tested at 100% Rg and UIS standards, it provides unparalleled efficiency and dependability for manufacturers across industries.
By combining state-of-the-art technology with practical enhancements, Vishay’s SiEH4800EW power MOSFET delivers both performance and reliability, meeting the rigorous demands of modern industrial applications.
