STW20NK70Z Description

Short technical summary and product information.

The STMicroelectronics STW20NK70Z is a single N-Channel MOSFET from the MOSFET (Metal Oxide) technology family. It is designed for through-hole mounting in a TO-247-3 package.

 

This MOSFET boasts a high drain-to-source voltage (Vdss) of 700V and can handle a continuous drain current of 20A (Tc) with a maximum power dissipation of 350W (Tc). Its on-resistance (Rds On) is a maximum of 285mOhm at 10A and 10V gate-source voltage. The gate charge (Qg) is 185nC (Max) at 10V, and the input capacitance (Ciss) is 6000pF (Max) at 25V.

 

The operating temperature range for this device is -55°C to 150°C (TJ). The gate threshold voltage (Vgs(th)) is a maximum of 4.5V at 150µA, and the maximum gate-source voltage (Vgs) is ±30V. The drive voltage is 10V.

 

Environmental compliance includes RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status. The device is suitable for applications requiring high voltage switching and power handling capabilities.
