S8050 is a commonly used NPN transistor. This transistor is used for audio amplification as well as a wide range of general-purpose applications in electronic circuits, such as switching. The S8050 transistor works as a low voltage, high current transistor device in applications, and as a result, S8050 transistors are used in more general-purpose circuits.
Its collector current is 0.7A (700mA), it can handle up to 700mA through its collector and emitter pins. As a result, we can only drive loads which are in 700mA limit. The maximum voltage this transistor can allow through its collector and emitter pins is 20V, therefore you can only use this transistor in circuits which operate under 20V. The transistor's normal gain value is 110, and its maximum gain value is 400. The maximum amplification of a signal that a transistor in an electronic circuit can achieve is indicated by the max gain value. The base current of this transistor is 5mA
The S8050 is an NPN transistor, when the base pin is held at ground, the collector and emitter are left open (reverse biased), and when a signal is applied to the base pin, the collector and emitter are closed (forward biased). It has a maximum gain of 400, this value determines the transistor's amplification capacity.

|When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region. When we supply current to the transistor's base, it makes a path for the collector current to flow from the base to the emitter. During Forward Bias, the transistor will act as an Open switch, and during Reverse Bias, it will act as a Closed switch||When in the Active Region, a transistor operates as an amplifier. It has the ability to amplify power, voltage, and current. The most popular and commonly used configuration is the common emitter type. The input is always applied at the forward-biased junction in the amplification transistor circuit. Similarly, the output can be collected across the reverse-biased junction of the transistor.|
The S8550 is a PNP transistor, when the base pin is held at ground, the collector and emitter are left open (reverse biased), and when a signal is applied to the base pin, the collector and emitter are closed (forward biased). It has a maximum gain of 300, this value determines the transistor's amplification capacity. S8550 is a widely used transistor, it is a reliable transistor with very good technical characteristics. The S8550 possess some very good features in its small TO-92 package.
The maximum collector current is -700mA, it can be used in a variety of electronic circuits for switching. The transistor's maximum gain is 400 which is also a plus point of this transistor. A maximum of 700mA current can flow between the collector and the emitter. The maximum voltage allowed between the Collector-Emitter (VCE) or Collector-Base (VCB) could be 20 or 30 volts, respectively.

|when a voltage is supplied to the base, a transistor conducts current across the collector-emitter. The switch is turned off when there is no base voltage. A transistor's switching operation is based on the voltage applied at the base terminal.||The input is always applied at the forward-biased junction in the amplification transistor circuit. Similarly, the output can be collected across the reverse-biased junction of the transistor. The input signal is applied to the base-emitter junction, and the output signal is sent through the load to the emitter-collector junction.|
