The BAV21-TR is classified as a diode-rectifier or a single diode. A diode is a device that has two electrical contacts, also referred to as terminals, where one terminal is positive and the other is negative. The purpose of a diode is to convert electricity from one form of energy to another by transferring electrical current in one direction only. Hence, the BAV21-TR can be used to rectify alternating current (AC) into direct current (DC).

The main application of the BAV21-TR is as a general-purpose rectifier for high-frequency switching regulators and voltage doublers. It is also used in low-noise voltage regulator circuits, as well as in adapters, polarized capacitors, inverters, power supplies, and various other electronic circuits. As for the working principle, in two-terminal diodes, the forward voltage is defined as the voltage across the two terminals when the diode is turned on and current is flowing through the diode. The reverse voltage of a diode is the voltage applied across the two terminals when the diode is turned off and no current is flowing through the diode.

The BAV21-TR specifically is used when high-frequency switched-mode power supplies are employed. Not only can its forward voltage be used in peak rectifiers, but also in power MOSFET gates. Additionally, it is used in a variety of other applications, due to its relatively low-noise voltage regulator capacity. For example, it can be used in mobile phones, laptop computers, and digital cameras.

The BAV21-TR is extremely versatile in terms of its application field, as well as its working principle. When forward voltage is applied to the two terminals of the BAV21-TR, current passes through the device in one direction only, thus being rectified from AC to DC. This is an extremely important process in the development of electronic devices, especially those related to digital technologies. As such, the BAV21-TR has become an invaluable device in modern electronics.
