![]() This makes it useful in applications where high-frequency signals need to be amplified or switched. This makes it ideal for use in battery-operated devices and other low-power applications.Īnother important characteristic of the 2N3904 transistor is its ability to operate at high speeds. One of the most important of these is its low power consumption. The 2N3904 transistor has several characteristics that make it useful in various electronic circuit applications. This typically involves setting the base voltage to a predetermined value using a voltage divider circuit. In order to use the transistor as an amplifier, it needs to be biased appropriately. ![]() The signal is then amplified at the collector and output as a larger signal at the emitter. To use the transistor as an amplifier, a small input signal is applied to the base. To use it as a switch, the transistor must be biased to be either fully on or fully off in order to control the flow of current through a circuit. The 2N3904 transistor can be used as a simple electronic switch or as an amplifier. The amount of current that flows between the collector and emitter is controlled by the amount of current flowing into the base. This current amplifies the signal at the base, allowing the transistor to be used as an amplifier. When a small current is applied to the base terminal, the transistor begins to conduct current between the collector and emitter terminals. It consists of three layers of semiconductor material: the emitter, the base, and the collector. The 2N3904 transistor is an NPN-type transistor.
