Working Principle

Bipolar transistors are a type of semiconductor device that are usually used as an amplifier or switching device. The BC807-16-TP are NPN transistors, meaning that their two terminals, the base (B) and the emitter (E), conduct a current when an external voltage is applied to the base. The external voltage is the switching signal, which when this current turning on and off (by transistors current gain), controlling the current flow between the collector (C) and the emitter (E). Thus, an electronic circuit with the BC807-16-TP can be used to amplify, as well as produce a switching action to control its current input.

Bipolar transistors have three regions – the emitter, base and collector – which are usually made up of either n-type or p-type semiconductor material. They are connected in series by two p-n junctions (a p-n junction is the junction between a p type and an n type semiconductor material). The BC807-16-TP transistors has a PNP connection arrangement, meaning the emitter is connected to a negative terminal, the base is connected to a positive terminal, and the collector is connected to a positive terminal. This type of connection makes it necessary to apply a constant current at the base-emitter junction to maintain the transistor in its “on” state and for it to be used as either an amplifier or a switch.

The BC807-16-TP transistors are used in applications where the input current needs to be controlled. For example, in power amplifiers, the transistors are used to control the current from the input signal so that it can be increased or decreased by varying the voltage applied to the base-emitter junction. In switching applications, the transistor can be used to produce a switching action to control its current input, or it can be used to act as an amplifier. In addition, due to its low noise, low saturation voltage and higher PNP current gain hfe, the BC807-16-TP offers improved performance compared to other transistors.
