STN4NF20L Description

Short technical summary and product information.

The STMicroelectronics STN4NF20L is an N-Channel MOSFET designed for power switching applications. It offers a high drain-source voltage (Vdss) of 200V and a continuous current rating (Id) of 1A at a case temperature of 25°C.

This MOSFET features a low on-resistance (Rds On) of 1.5 Ohm maximum at 500mA and 10V gate-source voltage, contributing to efficient power transfer. The gate charge (Qg) is 0.9 nC maximum at 10V, and the input capacitance (Ciss) is 150 pF maximum at 25V, important parameters for switching speed.

The device operates within a temperature range of -55°C to 150°C (TJ) and has a maximum power dissipation of 3.3W (Tc). It is available in a SOT-223 package, suitable for surface mounting.

The STN4NF20L is RoHS3 compliant and has an MSL rating of 1, indicating unlimited moisture sensitivity. Its REACH status is unaffected.
