BCX51,115 are both single transistors of the bipolar junction type (BJT). They are used in different applications, but their working principle is the same. In this article, we will explore their application field and working principle.The BCX51,115 are general-purpose transistors, commonly used in circuit designs including amplifiers, oscillators, and multi-vibrators. They have a moderate-to-high gain, which makes them suitable for low-power circuitry, as well as more intensive circuits with higher current needs.The BCX51,115 are particularly versatile because their pin configuration allows for use with a variety of circuit configurations. This means that the same device can be used in circuits with different current requirements, voltage levels, and even different physical sizes.The BCX51,115 have a three-pin configuration: the collector (C), the base (B), and the emitter (E). When power is applied, current runs from the base to the collector and from the collector to the emitter. This pn-junction makes for a working unit that is capable of amplifying and switching a wide range of voltages and currents.When the base is forward biased with a positive voltage, electrons will flow between the emitter and the base. This will result in holes in the base and provide an increase in the current that passes through the collector-emitter path. This will cause an increase in the voltage between the collector and the emitter. This is known as a positive voltage gain, and is how the BCX51,115 typically works as a transistor amplifier.The BCX51,115 are also capable of operating in the depletion mode. This means that when the base-emitter voltage is reversed, the electrons create a depletion region in the base, causing a decrease in the current through the emitter-collector path. This offers the advantage of creating a low-current switch.In conclusion, the BCX51,115 are highly versatile, single transistors of the bipolar junction (BJT) type. They are used in a wide range of applications, with their pin configuration allowing for use in virtually any circuit configuration. Their principal mode of operation is as an amplifier, with their pn-junction creating a positive voltage gain. They are also capable of operating in the depletion mode, allowing them to function as a switch.
