S8050 is a common NPN transistor. The transistor is designed for a variety of general purposes in audio amplification and electronic circuits such as switch applications.
What is S8050 transistor
S8050 is an NPN transistor, so when the base pin is grounded, the collector and emitter will remain open (reverse bias); when the signal is provided to the base pin, the collector and emitter will be closed (forward bias). The maximum gain is 400; the maximum gain is 400. This value usually determines the amplification capacity of the transistor s8050. Because it is very high, it is usually used for amplification purposes. However, under normal collector current, the typical value of gain is 110. The maximum current that can flow through the collector pin is 700mA, so we cannot use this transistor to drive loads that consume more than 700mA. To bias the transistor, we have to supply current to the base pin, which should be limited to 5mA.
When the transistor is fully biased, it allows a maximum current of 700mA to flow through the collector and emitter. This stage is called saturation zone, and the typical voltage allowed for cross collector emitter (VCE) or collector base (VCB) is 20V and 30V respectively. When the base current is removed, the transistor is completely cut off, which is called the cut-off region.

How does a S8050 transistor work?
ThAs mentioned before, the s8050 transistor is a general purpose transistor, which is an ideal transistor for performing small conventional tasks in electronic circuits. You can use it as a switch in an electronic circuit to turn on loads below 700mA. 700mA is enough for various loads, such as relay, led, bulb, etc. It can also be used as an amplifier in a small amplification stage or as a separate small signal amplifier.
To operate the transistor safely in a circuit or electronic project, do not operate the transistor at a voltage higher than 20V, nor at a load of 700mA or more than 0.7A. Use a suitable base resistance to limit the base current to the desired level. Do not expose to temperatures above 150 ° C and below – 60 ° C.
