Working Principle

The 2N3904RL1G transistor is an NPN type, it has three terminals, the base terminal, collector terminal and the emitter terminal. Its structure comprises of two pn junctions semiconductor layer, one on top of the from base to collector, and another one from collector to emitter. It works like a interrupter.

When no potential is applied to the base terminal of 2N3904RL1G transistor, the electrons from the emitter cannot pass through to the collector. When a suitable potential is applied to the base terminal, the flow of electrons from the emitter to the collector increases allowing the current to flow.

The current from the collector to the base terminal is very small as compared to the current from the emitter to the collector terminal. The collector current is usually proportional to the voltage applied to the base, which indicates that the current gain of 2N3904RL1G transistor is likely to be higher.

2N3904RL1G transistor is helpful in switching high current load with low voltage signals. As compared to the other type of transistor, 2N3904RL1G consumes less power and has relatively faster switching speeds. It can typically handle currents up to 200mA and collector-emitter voltage up to 40V.

2N3904RL1G is also used as a switch to apply, control, and regulate voltage levels for circuits that require higher switching time and heavier load conditions. It is used for the switching of small signals, circuits, power supplies and digital circuits.

2N3904RL1G is suitable for wide range of applications such as in robotics, gate-controlled applications, digital circuit designs, switching circuits, relay switches and in many other fields. The low power consumption, robustness and cost-effectiveness of 2N3904RL1G transistor makes it an ideal choice for many industrial, automotive and consumer applications.
