Hey Everyone! I hope you are doing great. We always come with some awesome topics related to engineering so you can excel and progress in your relevant field. Today, I am going to give you a brief details on the
Introduction to 2n1711. It is an NPN (Negative-positive-Negative) bipolar junction transistor (BJT) which is mainly used for amplification and switching purpose. It encompasses low leakage current, high break down voltage, and low capacity which makes it useful over widely current range. I'll try to touch every aspect related to this transistor so you can get an idea what it does and what are its main applications? Let's get started.
Introduction to 2n1711
- 2n1711 is an NPN bipolar junction transistor which is mainly used for switching and amplification applications.
- It consists of three terminals called emitter base collector and comes in TO-39 case style.
- It is a current controlled device where small current at the base side is used to control large current at the emitter and collector side.
- 2n1711 is a bipolar device where conduction is carried out by movement of both charge carriers holes and electrons.
- When we apply positive voltage at the base side, it gets biased and allows to control large current at the emitter and collector side.
- Base is actually acts like a handle which actually controls the flow of electrons emitted by emitter.
- These electron are then collected by collector. So base is actually controlling the conduction from emitter to collector terminals.
- In this NPN transistor, emitter is heavily doped while base side is lightly doped.
- Base side is positive with respect to emitter and P layer of this transistor lies between the two N-doped layers.
2n1711 Pinout
2n1711 mainly consists of three terminals which are described below.
1: Emitter
2: Base
3: Collector
- Small current at the base side is used to control the large current at the emitter and collector side.
- This process of controlling large current with the help of small current is used for amplification purpose.
- This transistor is mainly composed of silicon.
Circuit Diagram of 2n1711
Circuit symbol of 2n1711 is shown in the figure below.
- This NPN transistor can be configured into three main configuration i.e common base configuration, common emitter configuration and common collector configuration.
- Common emitter configuration is widely used for amplification purpose because it features the required voltage and power gain for amplification purpose.
- This configuration allows the input to increase by 20dB which is nearly 100 times more than input signal.
- It is important to note that collector voltage is higher than the base voltage.
- Current at the emitter side is the combination of both base current and collector current.
- Main difference between emitter and collector is their size and doping concentration. Collector is lightly doped while emitter is highly doped.
- In this transistor, base current is always the smallest current while emitter current is always the largest current.
- Forward current gain of the transistor is represented by beta ß. It is actually an amplification factor, the value at which current is being amplified. It is the ratio between collector current to the base current. As it is a ratio between two currents so it features no unit.
Absolute Maximum Ratings
Absolute maximum rating of 2n1711 is shown in the figure given below.
- These are the stress ratings of 2n1711. If values are exceeded from given values, it can harm the device at large.
- Collect base voltage is 75 V while collector emitter voltage is 50 V
- Maximum power it can dissipate is 3 W.
Mechanical Outline of 2n1711
Mechanical outline of 2n1711 is shown in the figure below.
- All dimensions are in mm.
- You must take these dimension into consideration before you intend to make a circuit so these dimensions can properly fit into the circuits.
Applications
- 2n1711 is mainly used for amplification purpose.
- In most of the circuits it is also used as a simple switch. When base is biased with the help of voltage, it allows the current to flow from emitter to collector. And in this state transistor remains in ON mode and acts as an ON switch. When there is no bias involved at the base side, the switch will be OFF.

Introduction to 2sc4793. It is an NPN (Negative-positive-negative) bipolar junction transistor (BJT) which is mainly used for amplification and switching purpose. I'll give you a brief details about this transistor and try to cover as many aspects as possible related to this transistor. Let's hop on the board and explore what kind of transistor is this and what are its main applications? Let's get started.
Introduction to 2sc4793
- 2sc4793 is an NPN bipolar junction transistor where P-doped layer is sandwiched between the two N-doped layer.
- It is mainly three terminal device which comes in TO-220F package and exhibits high transition frequency.
- Three terminals are called emitter base and collector.
- P layer of this transistor is behaved like a base while other two N layers represent collector and emitter receptively.
- As it is an NPN transistor, so base is positive with respect to emitter.
- It is a current controlled device where small current at the base side is used to control the large amount of current at the emitter and collector side.
- Unlike FETs(Field effect transistors), it is a bipolar device, where conduction is carried by the movement of both charge carriers i.e. electrons and holes.
- Sometimes you can see these transistor separated but most of the time they are incorporated in tiny integrated circuit.
- This transistor is widely used in many electronic application but mostly it is used for amplification and switching purpose.

- This silicon transistor is mainly remained in ON state when current flows from emitter to collector.
Circuit Diagram of 2sc4793
Following figure shows the circuit symbol of 2sc4793.
- As it is an NPN transistor, so base is positive as compared to emitter.
- In most NPN transistors, emitter side is heavily doped because its job is to emit number of electrons while base side is lightly doped because its job is to control the number of electrons emitted from the emitter side.
- These injected electrons are then collected by the collector. Hence, base controls the overall conductivity of the path between emitter and collector.
- Forward current gain of this transistor can be represented as Beta ß.
- It is a ratio between collector current and base current and it exhibits no units.
- Sometimes it is referred as a amplification factor because small change in base current causes a large change in collector current.
- Beta value ranges between 20 to 1000. Standard value in most of the cases is 200.
- The current gain of the transistor is represented by alpha a and it is a ratio between collector current and emitter current.
- Alpha value of transistor ranges between 0.95 to 0.99, however in most of the cases alpha value is considered as one.
- When voltage is applied at the base side, it gets biased and allows the current to flow from emitter to collector.
- When there in no voltage at the base side, transistor will be OFF, in case of positive voltage at the base, transistor is considered as ON.
Absolute Maximum Rating of 2sc4793
Absolute maximum rating of 2sc4793 is shown in the figure below.

- 2sc4793 is widely used in many electronic circuits as a voltage and power amplifiers.
- It is also used as switch in most circuits, because it exhibits high transition frequency.
