Chrysler had made the all-transistor car radio, Mopar model HR, available as an option starting in fall for its new line of Chrysler and Imperial cars which first hit the dealership showroom floors on October 21, The first commercial silicon transistor was produced by Texas Instruments in This was the work of Gordon Teal , an expert in growing crystals of high purity, who had previously worked at Bell Labs.
A Darlington transistor is effectively two transistors on the same chip. One transistor is much larger than the other, but both are large in comparison to transistors in large-scale integration because this particular example is intended for power applications. The transistor is the key active component in practically all modern electronics.
Many consider it to be one of the greatest inventions of the 20th century. A logic gate consists of up to about twenty transistors whereas an advanced microprocessor , as of , can use as many as 3 billion transistors MOSFETs.
Transistorized mechatronic circuits have replaced electromechanical devices in controlling appliances and machinery. It is often easier and cheaper to use a standard microcontroller and write a computer program to carry out a control function than to design an equivalent mechanical system to control that same function.

The essential usefulness of a transistor comes from its ability to use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals.
This property is called gain. It can produce a stronger output signal, a voltage or current, which is proportional to a weaker input signal; that is, it can act as an amplifier.
Alternatively, the transistor can be used to turn current on or off in a circuit as an electrically controlled switch , where the amount of current is determined by other circuit elements.
There are two types of transistors, which have slight differences in how they are used in a circuit. A bipolar transistor has terminals labeled base, collector, and emitter.

A small current at the base terminal that is, flowing between the base and the emitter can control or switch a much larger current between the collector and emitter terminals. For a field-effect transistor , the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain.
The image represents a typical bipolar transistor in a circuit. Charge will flow between emitter and collector terminals depending on the current in the base. Because internally the base and emitter connections behave like a semiconductor diode, a voltage drop develops between base and emitter while the base current exists. The amount of this voltage depends on the material the transistor is made from, and is referred to as VBE. Transistor as a switch[ edit ] BJT used as an electronic switch, in grounded-emitter configuration.
Transistors are commonly used in digital circuits as electronic switches which can be either in an "on" or "off" state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates.
Important parameters for this application include the current switched, the voltage handled, and the switching speed, characterised by the rise and fall times. In a grounded-emitter transistor circuit, such as the light-switch circuit shown, as the base voltage rises, the emitter and collector currents rise exponentially. Current gain values normally vary widely even for transistors of the same type so some variation will be acceptable.
Don't go for a transistor with a much higher Ft as this may increase the risk of oscillation. Choosing a replacement transistor with a similar can style will often mean that both transistors have a similar power dissipation. These are normally required when transistors are used in specialist applications.
Once the choice of replacement transistor has been made, then it can be installed in the circuit, and the performance checked. In most cases it will operate satisfactorily, but occasionally there may be a problem.
If this is the case, it is necessary to re-visit the way in which the choice of the replacement transistor was made and see if any mistakes were made or look for other parameters that may affect the operation of the transistor circuit.
What if I can't find the original transistor details? Sometimes it is very easy to find out the parameters of a particular transistor as it may be possible to find them on the Internet or in a transistor data book. If this is not possible, either because the markings are not visible, or the data cannot be found, then not all is lost. It is still possible to find out a lot about the transistor from its package and also the circuit in which it is being used. In this way it is usually possible to find a suitable replacement transistor.
The step by step instructions below should help the essential parameters of the transistor to be discovered. Step by step instructions: These instructions are set out in an approximate order of the most significant parameters first followed by the less significant ones: Is it a transistor?
This may appear to be an obvious question, but occasionally some devices may appear to be a transistor at first sight. It may be a field effect transistor, a Darlington transistor or even some other form of device. Alternatively, sometimes small voltage regulators are contained in packages similar to that of a transistor.
Other devices may also appear in what may appear to be transistor packages at first sight. Careful examination of the application will enable this to be verified.
It may be possible to discover this in a number of ways. If the original transistor is still working then this can be discovered by measuring the voltage across the base emitter junction when it is forward biased.
This should be about 0. Alternatively it may be possible to ascertain the type by looking at other transistors in the circuit. Often the same technology will be used throughout the equipment. This is not always true so beware! Look at the specifications for other transistors in the same packages and this will give a good guide.
Those packages designed for mounting on heatsinks will be more variable because they can often dissipate more power dependent upon the heatsink. It is best to be more cautious with these packages. High power transistors often offer lower gains - older power transistor types may be as low as 20 - 50, whereas the smaller transistors may offer gains anywhere between 50 and Look at the components in the circuit and the function of the circuit.
It is usually possible to estimate the frequency of operation. Then take this and choose a replacement transistor that can easily operate at this frequency. This is particularly true for specialised circuits where some specific performance features may be critical.
Summary Choosing a replacement transistor is normally quite easy.
Micro Electronics Transistors & IC Data Book Issue 1
There is a huge number of transistor types available, and the specifications of many types of transistor overlap, making the choice of a replacement transistor quite easy in many instances.Careful examination of the application will enable this to be verified. The replacement should have the same application if possible. Sometimes it is very easy to find out the parameters of a particular transistor as it may be possible to find them on the Internet or in a transistor data book.
