Vishay Intertechnology Unveils 40 V MOSFET With Industry-Leading RDS(ON) for Higher Efficiency
Vishay’s SiJK140E MOSFET with 0.34 mΩ RDS(ON) in PowerPAK 10x12 packaging enhances power density, efficiency, and thermal performance for industrial applications.
Compared to competing devices in the same footprint, the Vishay Siliconix SiJK140E slashes on-resistance by 32 % while offering 58 % lower on-resistance than 40 V MOSFETs in the TO-263-7L.
With on-resistance down to 0.34 mΩ typical at 10 V, the device released today minimizes power losses from conduction to increase efficiency while improving thermal performance with a low RthJC of 0.21 °C/W typical. By allowing designers to utilize one device instead of two in parallel to achieve the same low on-resistance, the SiJK140E also improves reliability and mean time between failures (MTBF).
The MOSFET features a bond-wireless (BWL) design that minimizes parasitic inductance while maximizing current capability. While TO-263-7L solutions in bond-wired (BW) packages are limited to currents of 200 A, the SiJK140E offers a continuous drain current up to 795 A for increased power density while providing a robust SOA capability. Occupying an area of 120 mm2, the device’s PowerPAK 10x12 package saves 27 % PCB space compared to the TO-263-7L while offering a 50 % lower profile.
The SiJK140E is ideal for synchronous rectification, hot swap switching, 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. To avoid shoot-through in these products, the standard-level FET offers a high threshold voltage of 2.4Vgs. RoHS-compliant and halogen-free, the MOSFET is 100 % Rg and UIS tested.
