TIP 42

TIP42 is a type of transistor, a tiny electronic switch that controls the flow of electrical current in circuits. It’s commonly used to amplify signals or switch larger currents on and off. TIP42 specifically is a NPN Bipolar Junction Transistor, meaning it turns on when a small current is applied to its base, allowing a larger current to pass between its collector and emitter. It's valued for its ability to handle moderate power levels and is often used in audio equipment, motor controls, and power supplies to efficiently manage electrical signals and power.
