The BSS138 is an N-channel MOSFET commonly used in low-power switching applications. It has a total of three pins.
1. Gate (G) - This pin is used to control the MOSFET. Applying a voltage (typically between 2-4V) to the gate allows current to flow from the drain to the source.
2. Drain (D) - This pin connects to the load. When the MOSFET is turned on, current can flow from the drain to the source.
3. Source (S) - This pin is connected to ground or the negative side of the power supply in most applications. It completes the circuit for current flow when the MOSFET is activated.
The BSS138 is widely used in digital circuits for signal switching, level shifting, and as a general-purpose switch due to its low on-resistance and fast switching capabilities.
