Similarly, the common-base current gain is the ratio between the collector current and the emitter current, which is called alpha and is denoted by α. It usually ranges from 20 to 1000, but the standard value is taken as 200. The common emitter current gain is the ratio between the collector current and the base current, which is called beta and is expressed as β. Two current gain factors: common emitter current gain and common base current gain play a crucial role in determining the characteristics of the transistor. The base is corrected with respect to the emitter, and the voltage on the collector must also be corrected with respect to the base. In the S8050 NPN transistor, electrons are the primary charge carriers, unlike the PNP transistor where holes are the primary charge carriers ![]() Once the current source is removed from the base terminal of the transistor, it will be turned off, so this stage is called the cutoff region. 20V and 30V are typical voltages used on VCE or VCB, respectively. Once the transistor is fully biased, it allows up to 700mA of current to be supplied through the emitter and collector terminals, so this phase is called the saturation region. Once the current supply is supplied to the base pin, which must be limited to 5mA, the transistor can be biased. However, the gain value for the collector current will be 110 and the maximum current supply across the collector terminals is 700mA, so we cannot control different loads by passing more than 700mA through this transistor. This value will determine the amplification capability and will be used if the amplification is very high. The S8050 triode has a maximum gain value of 300. In the S8050 NPN transistor, both terminals, emitter and collector, are reverse biased when the base is grounded, and they are closed (forward biased) when a signal is supplied to the base pin. When a voltage is applied at the base terminal, amplification is a simple way for the transistor to absorb a small current that is then used to control a large current at the other terminals. If the transistor is not forward biased, there will be no collector current no matter how much voltage is applied to the base terminal. It is important to note that the S8050 transistor must be operated in forward bias mode for better performance. The S8050 triode has two PN junctions: a forward-biased emitter-base junction and a reverse-biased collector-base junction. The S8050 transistor consists of three layers, with one P-doped semiconductor layer encapsulated between two other N-doped layers, the P-doped layer representing the base terminal, and the other two layers representing the emitter and collector, respectively. The S8050 is an NPN epitaxial silicon transistor with low voltage and high current capability that is a highlight for push-pull amplification and general purpose switching applications. ![]()
