NPN Silicon Transistor S8050 - Datasheet, Application Specifications, Pinout and Equivalent Replacements
S8050 is an NPN bipolar transistor. So when the base pin is connected to ground, the collector and emitter will remain open (reverse biased) and when a signal is supplied to the base pin, the collector and emitter will be closed (forward biased). It is commonly used in amplification and switching applications and is the perfect transistor to perform small and versatile tasks in electronic circuits. The electrical characteristics of the S8050 make it a very popular choice in many electronic circuits, especially in low and medium power circuits. The maximum gain value is 400; this value generally determines the amplification capability of the transistor S8050. If you are designing or repairing a circuit and need to check its specific parameters or application recommendations, we recommend that you refer to the S8050 data sheet.

S8050 frequently asked questions:
What type of transistor is the S8050?
The S8050 transistor is a general-purpose transistor that is perfect for performing small and general tasks in electronic circuits and is suitable for applications such as small and medium power amplifier circuits, switching circuits, etc.
What is the basic working principle of S8050?
Structure: The S8050 transistor has three main areas: emitter (E), base (B) and collector (C).
Operating Mode: When we refer to how a transistor operates, we are usually referring to its behavior in active mode or saturation mode.
Active mode: In this mode, a forward bias is formed between the base and the emitter, and a reverse bias is formed between the base and the collector. This allows a small current from base to emitter (base current, Ib) to control a larger current from collector to emitter (collector current, Ic).
Saturation mode: When the voltage at the base is high enough, a forward bias will also be formed between the base and the collector. In this case, the transistor is fully open and allows maximum current to flow.
Cut-off mode: When the base is unbiased or biased very low, the transistor is off and almost no current flows.
Current Gain (β or hFE): Current gain is the ratio between collector current and base current. The current gain of the S8050 is typically in the range of 100-300, which means that a small current through the base can control a larger current through the collector.
How to apply S8050?
Since the S8050 is a low-power NPN transistor, it is often used in signal amplification and switching small load applications.
How much does the S8050 cost?
S8050 unit price is US$0.04-0.08. This is a relatively cheap transistor. Of course prices always change and change over time, markets and regions.
