STB46NF30 Description

Short technical summary and product information.

This STB46NF30 is a single N-Channel MOSFET manufactured by STMicroelectronics. It features a high drain-to-source voltage (Vdss) of 300V and a continuous drain current (Id) capability of 42A at a case temperature of 25°C. The MOSFET has a low on-resistance (Rds On) of 75mOhm at 17A and 10Vgs, ensuring efficient power handling.

 

With a maximum power dissipation of 300W (Tc), this device is suitable for demanding applications. It operates within a temperature range of -55°C to 175°C (TJ). The gate charge (Qg) is 90nC at 10Vgs, and input capacitance (Ciss) is 3200pF at 25Vds.

 

The STB46NF30 utilizes MOSFET (Metal Oxide) technology and is designed for surface mounting. It comes in a TO-263-3, D²Pak (2 Leads + Tab), TO-263AB package, also known as D²PAK (TO-263). This package type is ideal for automated assembly processes and provides good thermal performance.
