STP46NF30 Description

Short technical summary and product information.

The STP46NF30 is an N-Channel enhancement-mode MOSFET manufactured by STMicroelectronics. It features a maximum drain-to-source voltage of 300V and a continuous drain current rating of 42A at 25°C case temperature. The device offers a maximum on-resistance of 75mOhm at 17A and 10V gate drive, making it suitable for high-efficiency switching applications.

 

Key electrical characteristics include a maximum gate threshold voltage of 4V at 250µA, a maximum gate charge of 90nC at 10V, and an input capacitance of 3200pF at 25V drain-source voltage. The maximum power dissipation is 300W at 25°C case temperature, and the device can operate at a junction temperature up to 175°C.

 

The STP46NF30 is housed in a TO-220 package, which is a through-hole mounting package suitable for power applications requiring good thermal performance. This MOSFET is designed for use in power supplies, motor control circuits, and other high-voltage switching applications where low on-resistance and high current capability are required.
