Field Effect Transistor in Static Relay: Field Effect Transistor in Static Relay is a unipolar device as compared to bipolar transistor already discussed. It consists of a bar of semiconductor…
Transistor Use in Static Relay: Transistor Use in Static Relay - In its simplest form, it consists of two pn junction diodes coupled together by a very thin common base,…
Transistor Relays: These are the most widely accepted type of static relays, so much so that when we say static relays, we can safely infer transistor relays only. The transistor…
Phototransistor Working: A Phototransistor Working is similar to an ordinary BJT except that its collector base junction is constructed like a photodiode. Instead of a base current, the input to…
Programmable Unijunction Transistor: PUT Operation - The Programmable Unijunction Transistor (PUT) is actually an SCR-type device used to simulate a UJT. The interbase resistance (RBB) and the intrinsic standoff ratio…
Field Effect Transistors Articles: Junction Field Effect Transistor Theory: n-Channel JFET – The operating principle of an n-channel Junction Field Effect Transistor Theory (JFET) is illustrated by the block representation…
Bipolar Junction Transistors Articles: Transistor Operation: pnp and npn Transistor Operation – A junction transistor is simply a sandwich of one type of semiconductor material (p-type or n-type) between two…
Darlington Connected Output Transistors: High-power transistors usually have low current gains, so relatively large base currents must flow into Q2 and Q3 to supply a high load current. This means…
