Pinout
The BF840 is an N-channel MOSFET transistor. It typically comes in a TO-92 package, which is a small plastic package commonly used for transistors. The pin count for the BF840 is three, and the pin functions are as follows:
1. Gate (G): This pin is used to control the flow of current between the drain and the source. By applying a voltage to the gate, the MOSFET is turned on or off.
2. Drain (D): This is the pin through which the main current flows from the load. When the MOSFET is turned on, current flows from the drain to the source.
3. Source (S): This pin provides the return path for the current flowing through the drain.
The BF840 is primarily used in switching applications due to its capability to handle relatively high voltages and currents with low input power, making it suitable for various electronic circuits.
