STW40NS15 Description

Short technical summary and product information.

The STW40NS15 is an N-Channel MOSFET manufactured by ST, utilizing the MESH OVERLAY™ process. This device is designed for high current switching applications, including uninterruptible power supplies (UPS) and primary switches in isolated DC-DC converters.

Key electrical specifications include a drain-source voltage (Vds) of 150V, a continuous drain current (Id) of 40A at 25°C, and a maximum pulsed drain current (Idm) of 160A. The typical static drain-source on-resistance (RDS(on)) is 0.042 Ohms at a gate-source voltage (Vgs) of 10V and a drain current of 40A. The typical gate threshold voltage (Vgs(th)) is between 2V and 3V.

Thermal characteristics include a maximum total power dissipation (Ptot) of 180W at 25°C and a maximum operating junction temperature (Tj) of 175°C. The component is housed in a TO-247 package, suitable for through-hole mounting.

This MOSFET offers extremely high dv/dt capability and minimized gate charge, contributing to efficient switching performance. Its design is optimized to improve performance compared to standard parts.
