2、BC547 Pinout Diagram & Testing BC547 Pinout (Note: Add actual image link in production) Pin 1 (Collector): Connects to load (LED/motor) in switching circuits. Pin 2 (Base): Control terminal – bias with 5-10mA via resistor (R = (Vin - 0.7V)/Ib). Pin 3 (Emitter): Ground re...
BC547 Transistor Circuit Diagram The ON/OFF touch switch using transistor BC547 is shown below. The circuit is activated once the power supply is given to the circuit. Once the supply is given to the circuit, the relay gets off mode. Thus, the base terminal of the Q3 transistor is high ...
