Transistors Buying Guide

Transistors are semiconductors that can amplify signals or switch them on and off. They are a crucial component in a wide range of electronic devices, including radios, computers, and televisions. Choosing the right transistor can be challenging as there are many different types and specifications to consider. In this buying guide, we will cover everything you need to know about transistors to help you make an informed decision.

Types of Transistors

There are two main types of transistors: bipolar junction transistors (BJT) and field-effect transistors (FET).

Bipolar Junction Transistors

BJTs consist of three layers of semiconductors. The first layer is called the emitter, the middle layer is called the base, and the last layer is called the collector. BJTs are either NPN (negative-positive-negative) or PNP (positive-negative-positive).

NPN transistors have a negative charge carrier (electron) flow from the emitter to the collector. PNP transistors, on the other hand, have a positive charge carrier (hole) flow from the collector to the emitter.

BJTs are commonly used for amplification applications and switching. They are relatively easy to use and have predictable voltage amplification characteristics. However, they can be affected by temperature changes, and their frequency response is limited.

Field-Effect Transistors

FETs are transistors that use an electric field to control the flow of current. FETs come in three different types: JFETs, MOSFETs, and MESFETs.

JFETs consist of a channel of semiconductor material that connects the source and drain terminals of the transistor. The current flows through this channel, and the gate voltage controls the resistance of the channel, which in turn controls the current flow.

MOSFETs have a metal gate electrode that is separated from the semiconductor channel by a thin layer of insulating material. The voltage applied to the gate controls the flow of current through the channel.

MESFETs are FETs that use a metal semiconductor junction as the gate. MESFETs are commonly used in high-frequency applications, such as satellite communication systems, due to their low noise levels and high gain.

Specifications to Consider

When choosing a transistor, there are several specifications to consider. Here are some of the most critical specifications:

Maximum Voltage (Vceo or Vds)

The maximum voltage is the highest amount of voltage that can be applied to the transistor before it breaks down. This specification should be considered when selecting a transistor for a high voltage application.

Maximum Current (Ic or Id)

The maximum current is the highest amount of current that can flow through the transistor before it becomes damaged. This is an essential specification for power applications, as the current flowing through the transistor can cause it to overheat and fail.

Gain (Hfe or Gm)

Gain is the ratio of the output current to the input current. It is a measure of the amplification capability of the transistor. A high gain transistor can amplify weak signals, while a low gain transistor is better suited for switching applications.

Maximum Power Dissipation (Pd)

Power dissipation is the amount of power that the transistor can handle without overheating. This specification is crucial for applications that require the transistor to handle high power levels.

Frequency Response (fT)

The frequency response is the range of frequencies that the transistor can amplify or switch. This specification is essential for high-frequency applications, such as radio communications.

Application Considerations

When selecting a transistor, consider the specific application for which it will be used. Here are some factors to consider:


If the transistor will be used for amplification, consider the required gain and frequency response. The gain should be sufficient to amplify the signal, and the frequency response should be wide enough to cover the desired frequency range.


If the transistor will be used for switching, consider the maximum voltage, maximum current, and switching speed required. The transistor should be able to handle the voltage and current without breaking down, and it should switch fast enough to meet the application's needs.

Power Applications

If the transistor will be used for power applications, consider the maximum voltage, maximum current, and maximum power dissipation. The transistor should be able to handle the power level without overheating or failing.

Package Types

Transistors come in various package types, each with its own advantages and disadvantages.


The TO-92 package is a popular transistor package type that is inexpensive and easy to use. The package consists of a plastic or metal casing with three leads. The leads can be bent to fit into a circuit board or wire wrapped.


The TO-220 package is a larger transistor package that can handle more power than the TO-92. The package consists of a metal casing with three leads. The leads can be bent to fit into a circuit board or heat sink attached.


The SOT-23 package is a small surface mount transistor package. The package consists of a plastic or metal casing with three leads. The leads are in a row and are spaced close together, making them suitable for densely packed circuit boards.


The DIP package is an older transistor package type that is still in use today. The package consists of a plastic or ceramic casing with two rows of leads. The leads can be bent to fit into a circuit board or inserted into a socket.


Choosing the right transistor for your application can be daunting, but with the information in this buying guide, you can make an informed decision. Consider the specifications and package types when selecting a transistor and factor in the specific requirements of your application.
