The transistor operates as switched ON in saturation mode and switched OFF in cut-off mode. When both junctions are connected in the forward bias condition and sufficient voltage is given to input voltage. In this condition, collector-emitter voltage is near to zero and the transistor operates a...
This type of transistor is known for its ability to handle large currents and high power dissipation. One of the key features of a high-voltage NPN power transistor is its ability to switch on and off rapidly. This is important in many applications where the transistorneeds to act as a ...
When being used as switches, NPN transistors are faster to switch. When the triode is being used as a switch, it works in two states: cut-off and saturation. Generally, the conduction and disconnection of the transistor are controlled by controlling the base voltage Ub of the transistor. II...

The two transistors can be used to perform the same thing, such as switching, but how to use them differs. Below I explain how both the NPN and PNP function and then depending on your application, you can choose whichever transistor is more applicable. NPN Transistor NPN transistors flow cur...
Fig. 4.6 shows a npn and a pnp transistor, the majority current flow in each, and the circuit symbol for each transistor. We will refer to this transistor as a bipolar junction transistor (BJT)—bipolar because holes and electrons are involved in its operation (although for the most part ...

Vertical NPN Transistor Operation. A vertical NPN transistor is a three-terminal semiconductor device that acts as an amplifier or switch. It consists of a thin layer of n-type semiconductor sandwiched between two layers of p-type semiconductor. The terminals are connected to the emitter, base, ...

NPN transistor switch circuitry, looks a bit odd. «on:May 10, 2020, 06:39:45 pm » Hi guys, I came across the following npn transistor circuit in a coffee grinder. The led D1 is the led of a MOC3063. It looks kind of peculiar to me as normally the 'load' this case the ...
