Vishay Intertechnology's Siliconix SiJK140E 40V MOSFET is said to reduce on-resistance by 32% while offering 58% lower on-resistance than 40V MOSFETs in the TO-263-7L.

Minimizes power losses from conduction to increase efficiency while improving thermal performance with a low RthJC of 0.21°C/W typical. Allows designers to utilize one device instead of two in parallel to achieve the same low on-resistance, improving reliability and mean time between failures. Features a bond-wireless (BWL) design that minimizes parasitic inductance while maximizing current capability, and offers a continuous drain current up to 795A for increased power density while providing a robust SOA capability. Occupies an area of 120 mm² in the PowerPAK 10x12 package, saving 27 % PCB space compared to the TO-263-7L while offering a 50% lower profile. Is ideal for synchronous rectification, hot swap switching, and OR-ing functionality, with typical applications being motor drive controls, power tools, welding equipment, plasma cutting machines, battery management systems, robotics and 3-D printers. Offers a high threshold voltage of 2.4Vgs, is RoHS-compliant and halogen-free, and is 100% Rg and UIS tested.
