STF12N50M2 Description

Short technical summary and product information.

The STF12N50M2 is an N-Channel enhancement mode power MOSFET manufactured by STMicroelectronics. It features a maximum drain-source voltage of 500V and continuous drain current of 10A, making it suitable for high-voltage switching applications. The device uses silicon technology with a single channel and is designed for efficient power conversion.

 

Switching performance is characterized by a typical rise time of 10.5 ns and fall time of 34.5 ns, with turn-on and turn-off delay times of 13.5 ns and 8 ns respectively. The gate charge is specified at 15 nC maximum at 10V, and the input capacitance is 560 pF at 100V drain-source voltage. These parameters support high-frequency operation with minimized switching losses.

 

The STF12N50M2 is offered in a TO-220FP-3 through-hole package with an operating junction temperature range from -55°C to 150°C. Maximum power dissipation is 85W. The package style facilitates easy mounting on printed circuit boards for prototyping and production runs.
