The BZX55C8V2-TR is a diode used in electronic circuits for voltage regulation or signal filtering. It belongs to a category of diodes called Zener Diodes and is part of the “Single” type.In general, diodes allow electrons to travel in one direction when a voltage is applied to them. The BZX55C8V2-TR is unique in that it can also regulate the voltage applied when it surpasses a certain value. This regulation is called zener breakdown and it is a specific behavior that many electronic components take advantage of for their design needs.The specific application fields for the BZX55C8V2-TR are varied, but some examples of these are power supplies, reference sources, voltage detection circuits and signal filtering components as part of a circuit. Due to its voltage regulation capacity, it is also often used in battery operated devices where it is desirable to maintain the same operation voltage range.To better understand the working principle of this diode, it is essential that we first understand the concept of breakdown voltages. This is a specific behavior in materials where, once a certain electrical stress is applied, a conductive “track” is formed and the material becomes more conductive existing electrons. In the case of the BZX55C8V2-TR, this behavior occurs when an applied forward voltage reaches 8 Volts. When this occurs, the zener breakdown occurs, and the diode starts acting like a voltage regulator, limiting the voltage to a much lower value around 6.2 Volts. This is a desirable behavior for many electronic components as it limits their operation voltage to the region where the component works best, and thus provides better overall performance to the circuit.To summarize, the BZX55C8V2-TR is a single type Zener Diode that is used in many electronic circuits for a myriad of applications. Its principle of operation is based in a property called zener breakdown where, when the current forward voltage reaches 8 Volts, the diode conducts more electrons and this causes the reduction of the current forward voltage to 6.2 Volts, thus acting as a voltage regulator.
