NSS40201L

The NSS40201L is a high-performance N-channel MOSFET manufactured by onsemi, designed for efficient power management in demanding applications. It features a low RDS(on) of 3.5 mΩ at VGS = 10 V, enabling minimal conduction losses and high energy efficiency. The device supports a maximum drain-source voltage (VDS) of 20 V, making it suitable for low-voltage DC-DC converters and battery-powered systems. With a continuous drain current rating of 80 A at 25°C junction temperature, the NSS40201L ensures reliable operation under heavy load conditions. This MOSFET incorporates advanced trench technology to optimize gate charge (Qg) and switching speed, reducing switching losses and improving overall system efficiency. Its low gate threshold voltage (Vth) of 1.0 V allows compatibility with low-voltage control circuits such as those found in microcontrollers or digital signal processors. Additionally, the device exhibits excellent thermal performance due to its optimized package design—offering low thermal resistance (RθJC) and robust mechanical structure for enhanced heat dissipation. The NSS40201L is ideal for use in power delivery systems, including USB Power Delivery (USB-PD), buck converters, and motor drivers. It is particularly well-suited for consumer electronics like smartphones, tablets, and portable devices where compact size, high efficiency, and thermal stability are critical. Its rugged construction also makes it appropriate for industrial and automotive applications requiring reliability under harsh environmental conditions. Built with a TO-220-3L package, the NSS40201L provides a balance between cost-effectiveness and performance, while ensuring easy integration into existing PCB layouts. The device meets RoHS compliance and is designed for lead-free soldering processes, aligning with modern environmental standards. Its consistent electrical characteristics across temperature and time ensure long-term reliability in mission-critical applications.
