What is Datasheet of a transistor?
To select a transistor for a particular application, the Transistor Datasheet provided by device manufacturers must be consulted. Most data sheets start off with the device type number at the top of the page, a descriptive title, and a list of major applications for the device.
What do the numbers mean on a transistor?
The first letter represents the material. For instance, A means germanium and B means silicon. The second letter refers to transistor type. For instance, C means small signal and D means power. The first digit is the number of leads minus one, so it will be 2 for a bipolar transistor.
What are transistor parameters?
TRANSISTOR PARAMETERSt Parameters are simply numerical constants which relate currents and potentials in a device. For example in a triode there are 3 para- meteres namely, the plate resistance (rp), the transconductance (gm) and the amplification factor (~). These are also known as valve constants.
Why transistor is called bipolar device?
Bipolar transistors are a type of transistor composed of pn junctions, which are also called bipolar junction transistors (BJTs). Whereas a field-effect transistor is a unipolar device, a bipolar transistor is so named because its operation involves two kinds of charge carriers, holes and electrons.
What are the two basic types of transistors?
Transistors typically fall into two main types depending on their construction. These two types are bipolar junction transistors (BJT) and Field Effect Transistors (FET).
What is the most common diode?
The most commonly used signal diode is the 1N4148. This diode has a close brother called 1N914 that can be used in its place if you can’t find a 1N4148. This diode has a forward-voltage drop of 0.7 and a peak inverse voltage of 100 V, and can carry a maximum of 200 mA of current.
How many types of transistors are there?
Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors: BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs). A bipolar transistor is a type of transistor that uses both electrons and holes as charge carriers.
