Where to use BC107 Transistor

The BC107 is a low signal NPN which is known for its low noise operations making it famously used in signal processing circuits and television receivers. The transistor is still available in market due to its legacy but you will find better modern transistors as replacement for BC107.

Brief Description on BC107 Transistor

BC107 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. BC107 has a gain value hfe of 50; this value determines the amplification capacity of the transistor. The maximum amount of current that could flow through the Collector pin is 100mA, hence we cannot connect loads that consume more than 100mA using this transistor.

When this transistor is fully biased then it can allow a maximum of 100mA to flow across the collector and emitter. This stage is called Saturation Region. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.

 Applications

  • Driver Modules like Relay Driver, LED driver etc..
  • Amplifier modules like Audio amplifiers, signal Amplifier etc..
  • Darlington pair
