The STMicroelectronics STW40NF20 is an N-Channel Power MOSFET utilizing the STripFET process, designed to minimize input capacitance and gate charge for high-efficiency isolated DC-DC converters. It features a drain-source breakdown voltage of 200V and a continuous drain current rating of 40A at 25°C.
Key electrical characteristics include a maximum Rds On of 45mOhm at 20A and 10V, a gate-to-source voltage (Vgs) maximum of ±20V, and a threshold voltage of 4V at 250µA. The input capacitance (Ciss) is rated at 2500pF at 25V, and the gate charge (Qg) is a maximum of 75nC at 10V.
This MOSFET operates within a temperature range of -55°C to 150°C (TJ) and has a maximum power dissipation of 160W (Tc). It is housed in a TO-247-3 package and supports through-hole mounting.
The STW40NF20 is suitable for switching applications and is manufactured by STMicroelectronics. It is RoHS compliant and has a Moisture Sensitivity Level (MSL) of 1.
