How do you use a BC547 as a switch?
Useful Steps
- Place Transistor on a breadboard.
- Connect Emitter to the ground of the battery.
- Add LED & 330 Ohm Resistor to Collector of BC547.
- Connect 1k Resistor and Switch to Base of transistor.
- Power up the circuit with 9V Battery.
How many pin does BC547 transistor has?
BC547 is an NPN Bipolar Junction Transistor. And like all other transistors, BC547 has three pins called the emitter, collector, and base respectively.
How does a 547 transistor work?
BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BC547 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
What is the output of BC547?
The maximum current gain of BC547 is 800mA. Collector-Emitter Voltage is 65V. Collector-Base Voltage is 80V. Emitter-Base Voltage is 8V.
What is the function of pins 1 and 2 in BC547?
bc547-transistor-pin-configuration Pin1 (Collector): This pin is denoted with symbol ‘C’ and the flow of current will be through the collector terminal. Pin2 (Base): This pin controls the transistor biasing. Pin3 (Emitter): The current supplies out through emitter terminal
What is the function of transistor biasing pin BC547?
This pin controls the transistor biasing. The current supplies out through the emitter terminal. This transistor has two working states, one is Forward Bias and another one is Reverse Bias. BC547 is an NPN transistor. So, when we will apply positive voltage at the base terminal of this transistor, then it starts working as Forward Bias.
How does the BC547 work?
BC547 is an NPN transistor so when no power is applied to the base, the collector and emitter will be left open (Reverse biased). When a positive voltage is applied to the base pin, the transistor will turn on. The max gain of this transistor is 800, which determines the amplification factor of the device.
What is the maximum gain current of BC547 transistor?
The maximum gain current of BC547 transistor is 800A. The flow of current will be through the collector terminal. This pin controls the transistor biasing. The current supplies out through the emitter terminal.
