STP40N20 Description

Short technical summary and product information.

The STMicroelectronics STP40N20 is a high-performance N-Channel Power MOSFET designed for efficient switching applications. It features a robust 200V Drain-Source Voltage (Vdss) and can handle a continuous drain current of up to 40A at a case temperature of 25°C, with a maximum power dissipation of 160W.

 

This MOSFET utilizes Metal Oxide Semiconductor (MOS) technology and is housed in a standard TO-220 package, making it suitable for through-hole mounting. Key electrical characteristics include a low on-resistance of 45mOhm at 20A and 10V, a gate threshold voltage of 4V at 250µA, and a maximum gate charge of 75nC at 10V. The operating temperature range is from -55°C to 150°C (TJ).

 

The STP40N20 is part of the STripFET™ series, known for minimized input capacitance and gate charge, making it ideal for advanced high-efficiency isolated DC-DC converters. Its design ensures good manufacturing repeatability and an excellent figure of merit (RDS*Qg).
