Introduction to S8050 – NPN Transistor

Hi guys welcome to the new post. Here we will learn Introduction to S8050 – NPN Transistor. The transistor is an electronic device that is used as a switch and amplifier in different projects. Different types of transistors are existed according to features and applications. But most commonly used as NPN and PNP. NPN has a larger doping area for N material and PNP has P types material large doped.

Both of these transistors are used for different applications. In this post, we will discuss the main parameters of the S8050 transistor in detail. So let get started.

Introduction to S8050 – NPN Transistor

• The S8050 is less voltage operating and high current used device comes in NPN configuration.

• It is the basic part of class B push-pull amplifier circuits and is mostly employed as a general-purpose transistor.
• Its gain value lies between one ten to four hundred. Gain is a term that tells the amplification power of the transistor.
• Its collector current has an extreme value of seven hundred milliamperes.
• Due to the NPN configuration collector and emitter in a reverse-biased state if the base is linked to the ground and if the voltage is given at the base it is a forward-biased state.
• Its completely biased state called saturation value of volts about VCE is about twenty volts.

 

• If there is no base current it is called a cut-off state.

S8050 – NPN Transistor Pinout

• There are three main pinouts it has been described here
• Emitter: Current comes out through this pinout and has larger areas than the base but less than a collector
• Base: It works as control of transistor-like tap
• Collector Larger part of a transistor and has features to current.

• S8050 transistor is used for small signal processing like audio amplifier switching circuits. The value of gain is 40 to 400 and helps to amplify small input signals in larger signals

S8050 Transistor Working

There are two modes of working for this transistor forward forward-biased and reverse-biased

Forward Bias

• If the S8050 collector pin is connected in forward-biased mode collector voltage is higher than the base voltage, Pn junction will be in forward-biased condition.
• In this condition, forward-biased voltage is produced between the base and emitter resulting base region being small and increasing carrier concentration. Forward bias voltage attracts a larger number of electrons coming from the emitter to the base region and same time larger number of holes moves from the base to the emitter.  For forward bias condition conductive channel is made between collectors and emitter and current flows from the collector to the emitter.

Reverse Bias

• If the collector of the transistor has a reverse polarity connection the battery collector voltage is less as compared to the base voltage. Pn junction will be in reverse biased condition.
• In this condition reverse bias voltage is produced between the base and emitter and results in depletion region to larger size and carrier concentration reduces.
• Reverse bias voltage avoids the movement of electrons from emitter to base and also controls hole flow from base to emitter.
• In this condition cutoff channel is created between the collectors and the emitter of the transistor and the current does not flow collector to the emitter.

Difference Between S8050 and SS8050

• S8050 and SS8050 are types of transistors but have some differences.
• S8050 comes with a high drain voltage value of about -40V and SS8050 comes with a drain voltage of about -25V.
• With that S8050 has features to handle high drain current about 700mA and SS8050 has features to handle  1.5A of maximum drain current.
• S8050 is a PNP transistor and SS8050 is an NPN transistor.

S8050  transistor Equivalent Transistors

• Some transistor such as S9013 and the 2N5830 comes with the same amplification features as S8050. With that, there are some other transistors used as equivalents of S8050 such as  MPSA42, 2N3055, 2N3906, 2N2369, and BC547.

Where to use S8050 Transistor 

• S8050 is known as a general purpose transistor so it is used for different circuits such as small circuits. It is used as a switch in different circuits.
• it also has features to control loads that are below the value of the 700mA threshold. Current is enough for operating most of the small power devices such as those used to operate LEDs, relays, and bulbs.
• It is also used for amplification of small signals.
