STF3NK80Z Description

Short technical summary and product information.

The STMicroelectronics STF3NK80Z is a single N-Channel MOSFET from the MOSFET (Metal Oxide) technology family. It is rated for a maximum drain-to-source voltage (Vdss) of 800V and a continuous drain current of 2.5A at the case temperature (Tc).

 

Key electrical characteristics include a maximum on-resistance (Rds On) of 4.5 Ohms at 1.25A and 10V gate-source voltage, a gate charge (Qg) of 19 nC maximum at 10V, and an input capacitance (Ciss) of 485 pF maximum at 25V. The gate-to-source voltage (Vgs) has a maximum rating of ±30V, with a gate threshold voltage (Vgs(th)) of 4.5V maximum at 50µA.

 

This MOSFET operates within a temperature range of -55°C to 150°C (TJ). It has a maximum power dissipation of 25W at the case temperature. The component is mounted via a through-hole method and comes in a TO-220-3 Full Pack package, also referred to as TO-220FP by the supplier.

 

The STF3NK80Z is RoHS3 compliant and has an MSL rating of 1 (Unlimited).
