Pinout
The STP9NK50Z is a power MOSFET manufactured by STMicroelectronics. It typically comes in a TO-220 package, which has three pins. The pin configuration and functions are as follows:
1. Pin 1 (Gate): This pin is used to control the MOSFET. By applying a voltage to the gate, it allows current to flow between the drain and source. The gate operates with a low voltage signal to turn the MOSFET on or off.
2. Pin 2 (Drain): This pin is the terminal through which the main current flows from the drain to the source when the MOSFET is turned on. It is connected to the load in a circuit.
3. Pin 3 (Source): This pin acts as the return path for the current flowing through the drain. It is typically connected to the ground or the negative side of the power supply.
Additionally, the tab of the TO-220 package is usually connected to the drain and can be used for heat dissipation. The STP9NK50Z is designed for high-voltage applications, with a maximum drain-source voltage (V_DS) of 500V and a drain current (I_D) of 8.5A.
