16N50E Pinout: Understanding the Power MOSFET
The 16N50E is a popular power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) widely used in various electronic applications, including power supplies, motor control, and switching circuits. To ensure proper usage and avoid damage, it's essential to understand the pinout of this device.
16N50E Pinout Diagram
The 16N50E comes in a TO-220 package with three pins: Gate, Drain, and Source.
Pin 1: Gate (G)
- The Gate pin is responsible for controlling the flow of current between the Drain and Source pins.
- It's connected to the control circuitry, such as a microcontroller or a voltage regulator.
- A positive voltage applied to the Gate pin turns the MOSFET on, allowing current to flow between the Drain and Source pins.
Pin 2: Drain (D)
- The Drain pin is the output pin, where the load is connected.
- It's the terminal where the current flows out of the MOSFET.
- The Drain pin is normally connected to the positive supply voltage or the load.
Pin 3: Source (S)
- The Source pin is the input pin, where the current flows into the MOSFET.
- It's normally connected to the negative supply voltage or ground.
