How does a transistor work: the basicsA transistor can be considered as two P-N junctions placed back to back. One of these, namely the base emitter junction is forward biased, whilst the other, the base collector junction is reverse biased. It is found that when a cu...
BJTs and MOSFETs are the types of transistors used in power electronics, along with insulated-gate bipolar transistors. IGBTs combine the strengths of BJTs and MOSFETs; they handle current the way BJT does but have the voltage control of a MOSFET. This makes them viable alternatives to BJTs a...
The two most common types are the Bipolar Junction Transistor (BJT) and the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). The BJT is a transistor that uses both electron and hole charge carriers, and it comes in two types: NPN and PNP. It consists of three layers of ...
IV How does the CPU work? As we all know, the CPU is the "heart" of the computer and the core of the entire microcomputer system. Therefore, it is often synonymous with various grades of microcomputers, such as 286, 386, 486, Pentium, PII, K6 to today's PIII, P4, K7, and so ...
How to identify Relay Pinouts and Connect a Relay Normally and unfortunately many relays don’t have there pinout marked, which makes it difficult for the new electronic enthusiasts to identify them and make these work for the intended applications. ...
It consists of three layers of doped semiconductor material, namely the emitter, base, and collector, and can be either NPN or PNP type. How does a BJ transistor work? A BJ transistor works by controlling the flow of current between the emitter and collector terminals, using the base...
In an earlier question I asked about driving a speaker with a BJT transistor. @Jonk offered a push-pull amplifier design of his own, and @G36 noted its similarity to the JLH amplifier described in a paper from 1969. In 1969 NPN power transistors were easier to ...
Basically this kind of circuits work using ablocking oscillatorfor pulsating a high voltage ferrite transformer. Here, the main active component is a small signal BJT which operates in a push pull manner for creating the required pulses across the transformer winding. ...
Below is the pinout of a BJT: Looking at the back side of the transistor, the emitter is the first pin, the base is the middle, and the collector is the third. To connect the transistor as a switch in a circuit, we connect the output of the device that will switch on the transisto...
For example let's say if you used 2N3055 for the BJT, since the max current handling capacity of the device is around 15 amps, 70% of this would be around 10.5 A. Therefore, assuming the V= 12V, then R = 12/10.5 = 1.14 Ohms ...
