Additionally, LTSpice has a powerful built-in waveform viewer, which can be used to analyze the simulation results. It also has a user-friendly interface, making it easy to use for both beginners and experienced users. It has a large library of models and components, allowing users to simulate a wide variety of circuits. It is a free, powerful and easy-to-use tool for simulating analog circuits. LTSpice is a high-performance SPICE simulation program developed by Linear Technology, now part of Analog Devices. If you are designing a PCB or Perf board with this component then the following picture from the S8050 transistor Datasheet will be useful to know its package type and dimensions.LTSpice and Proteus are both popular circuit simulators, but they have different features and capabilities. A simple circuit diagram of the Class B amplifier with the using the S8050 is shown below. Like here the NPN transistor will be S8050 and its equivalent PNP transistor will be S8550. 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. 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.
