STB40NF20 Description

Short technical summary and product information.

The STMicroelectronics STB40NF20 is an N-Channel MOSFET designed for robust power applications. It features a maximum drain-source voltage (Vdss) of 200V and can handle a continuous drain current of 40A at case temperature.

 

Key electrical characteristics include a low on-resistance (Rds On) of 45mOhm at 20A and 10V Vgs, and a gate charge (Qg) of 75nC at 10V Vgs. The gate threshold voltage (Vgs(th)) is 4V at 250µA. The device operates within a temperature range of -55°C to 150°C (TJ).

 

This MOSFET is housed in a TO-263-3, D²Pak (2 Leads + Tab), TO-263AB package, suitable for surface mounting. Its high power dissipation capability of 160W (Tc) makes it suitable for demanding applications.
