A simple circuit diagram of the Class B amplifier with the using the S8050 is shown below. BC547 transistor’s first pin is collector, second is base and third is Emitter while the 2N2222 transistor’s first pin is emitter, second is base and third is Collector. Like here the NPN transistor will be S8050 and its equivalent PNP transistor will be S8550. By looking at the above pin comparison image above we can understand that pin configuration of both the transistors are different. By complimentary it means that we need a NPN transistor and its equivalent PNP transistor. It is very simple to construct and requires two identical complimentary transistors operate. So let us discuss how that is done.Ī push pull amplifier, commonly known as Class B amplifier is type of multistage amplifier commonly used for audio amplification of loudspeakers. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.Īs mentioned in the features of the S8050 transistor is commonly used in push pull configuration with Class B amplifier. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (VCE) or Collector-Base (VCB) could be 20V and 30V respectively.

When this transistor is fully biased then it can allow a maximum of 700mA to flow across the collector and emitter. (Including GST) Purchase this product now and earn 4 Robu Points Add to cart. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA. The maximum amount of current that could flow through the Collector pin is 700mA, hence we cannot drive loads that consume more than 700mA using this transistor.

However at a normal operating collector current the typical value of gain will be 110. Since it is very high it is normally used for amplification purposes. It has a maximum gain value of 400 this value determines the amplification capacity of the transistor normally S8050. S8050 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.
