When it comes to switching and amplification operations, there are various electronic components that you will look out for.

One of them is the transistor.

But again,there are various types of transistors designed for this job.

One of them is the S8050 transistor.

What is it and should I consider buying it?

Well, here is a perfect guide for you.

We are going to get deep into this electronic components.

I will also guide you on how to choose the best S8050 transistors  from the best suppliers in China.

What is S8050 Transistor?

First things first,lets get ahead with the definition.

This is a an NPN transistor that is mainly used for the switching and amplification functions.

The P layer of the transistor is well-encapsulated between the N layers hence the NPN configuration.

S8050 transistor is perfectly designed for optimum performance in whichever applications that it used in.

The NPN design means that it has the collector emitter and the base terminals.

Of course the base terminal of the transistor is grounded while the rest are connected to the circuit.

S8050 transistors are commonly used in the class B amplifiers( amplifiers that use the class B transistor configuration).

Also the transistor has a low voltage and high current characteristic.

Which class does this transistor belong to?

Probably you are aware that transistor belong to two major classes. These are BJT and UJT.

The S8050 transistor belongs to the BJT transistors class (Bipolar Junction Transistor)

This means that it has two major carriers. These are holes and electrons with the later forming the major part of the carriers.

Other than the two classes we have to know the biases of the S8050 transistor. Is it Forward Biased or Reverse biased?

To get the optimum performance out of this transistor, it will be wise to forward bias it, unless you have no other option.

S8050 transistor Pin configuration

Pin configuration refers to the the arrangement of pins in transistors

S8050 transistor has three pins. These are:

Pin 1(Emitter): This pin that allows the current to drain out of the transistor.

Pin 2 (Base): This pin makes it possible to execute the biasing operations.

Pin 3(Collector): This is this supply current pin. It gets the electric current into the transistor.

As you can see, each pin has a specific function. So, when handling the transistor, it will be prudent to identify each of them before you connect it to the circuit.

Key features and specifications of theS8050 transistor

Now let’s look at the key characteristics that define the S8050 transistor.

• Transition Frequency of 150 MHz
• Categorized as a high current and as well as low voltage transistors
• DC current gain(hFE) of between 40 to 400

How does S8050 transistor work?

Now that you know the basics, let look at how this transistor works.

S8050 transistor working principle is similar to the other transistors when they are connected to their respective electric circuits.

As we have stated about the configuration, S8050 transistor has three terminals: The emitter, the base and the collector.

The emitter and the collector are reverse-biased while the base(which is grounded) is forward biased.

This configuration ensures that the signal is supplied to the base pin.

From the S8050 transistor specifications, it is clear that it has a  max gain value of 300. This is the value that will determine the level  of amplification that you will get.

If you want to get the best amplification,then the gain value should definitely be high.

Let’s say if the gain value based at the collector is 110 and the supply current at the same terminal remains at 700mA, it will be difficult to control  different loads that are designed to operate at the current value of more than 700mA.

You can only bias a S8050 transistor only if the current supplied at the vase terminal remains at 5mA.

Once you completely bias the transistor,it will end up creating an operational phase known as the Saturation Region.

Thus phase is created when you supply 700mA current across the emitter and the collector terminals.

Similarly,the voltage across  VCE and VCB should be between the 20V and 30V.

Once you terminate the supply current at the base terminal, the transistor will go off. This new phase is known as the Cut-off region.

And based on this working principle, you can tell why it is easy to use S8050 transistor for both switching and amplification operations.

Application of S8050 transistor

Where is S8050 transistor used?

Here are some of the application areas of this NPN transistor.

-Loading function: S8050 transistors are used to perform the general loading functions in electric circuits. This is possible as it can activate the loads of below 700mA.

-Lighting devices: Lighting devices such as LEDs and rbulbs use this transistor to switch on and off.

-Relays: Since relays operate like switches, these transistors will controlteh on and off actions.

-Audio amplification

-Push-pull circuits

-Low gain and high gain amplification

What project or device are you working on? Do you think it will require  an S8050 transistor?

How to protect S8050 transistor

From the working operation and even applications, you can tell that S8050 transistor is quite a sensitive transistor. So, you should put appropriate protection mechanism.

One way of protecting it is by limiting its operation voltage to 20V. Also, avoid exposing it to temperatures of over  150C or below-60C.
