Description

BC546 Transistor

The BC546 is a high-frequency NPN Transistor commonly used in low noise amplifier designs. It has a maximum gain value of 800 and a high collector to emitter voltage of 65V making it also suitable for high voltage audio amplifier applications(Click for wide range of Transistors).

BC546 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. It is a low current transistor hence the maximum amount of current that could flow through the Collector pin (Ic) is 100mA, hence we cannot connect loads that consume more than 100mA and load voltage more than 30V using this transistor. BC546 has a decent gain value hfe up to 800; this value determines the amplification capacity of the transistor.

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

The BC546 is a popular NPN Amplifier transistor that can be found in many audio pre-amplifier designs. The Transistor has a gain value of 800 with a transition frequency of 150MHz, the transistor is also know for its low noise feature.

The BC546 has very low Continuous current of 100mA with a collector to emitter voltage of 65V, hence it cannot be used to switch heavy loads. So it can be used in places where the load current is less than 100mA
