When to choose a replacement transistor for an electronic circuit?
When choosing a suitable replacement transistor for use within an electronic circuit, there are several stages that must be considered when making the choice. These can be progressed in a logical order to narrow down the choice and enable the best alternative for the replacement transistor to be made.
Are there any other devices similar to a transistor?
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.
Which is an example of an application for a transistor?
Possible application types may include: switching, analogue, low power, RF amplifier, low noise, etc. Put in the correct type and it may not perform well. For example a low power general-purpose transistor is unlikely to work well in a switching application even if it has a high ft or frequency limit.
Which is larger the collector or the emitter in a transistor?
In an actual transistor, the collector region is normally larger than the emitter region, and none of them is square as shown in the diagram. The diode representation of the transistor indicates how current flows, not how the actual part is constructed.
What happens if you install the wrong type of transistor?
Install the incorrect type and it experience the inverse of all the voltages it would expect and is likely to be destroyed. General application: Although it is not always necessary to exactly match the intended purpose for the transistor, a variety of areas of its performance will be tailored to its intended applications.
How are transistors used to do mechanical work?
When you need to do mechanical work on something, if you add leverage, you can amplify your work. The physics of transistors allows us to use either voltage or current to manipulate leverage of electrical energy in the transistor. The net effect is that we can use a little voltage or current to control a much larger voltage or current.
