Diodes are an essential component in any electrical system and have a wide range of applications. The BZX85B20-TAP is one such component and is used in many different systems. This article aims to examine the different application fields and the working principle of the BZX85B20-TAP.

First, let\'s take a look at some of the most common application fields for the BZX85B20-TAP diode. It is often used in telecommunications systems due to its high reverse voltage ratings and its small size. Its low power output and its moderate surge handling capability makes it ideal for many RF and microwave power applications. It is also commonly used in computers, in particular to provide power conditioning and filtering.

In addition to its application fields, the BZX85B20-TAP diode also has a unique working principle. It is a Zener diode, which is composed of a junction between two materials of different doping types. This junction creates a reverse-biased PN junction, which in turn creates a potential barrier between the two materials. For this reason, the BZX85B20-TAP acts as a voltage-dependent resistor, allowing current to flow in only one direction.

When a voltage is applied in the forward direction, the diode acts as a normal diode and the current flows freely in the forward direction, limited only by the diode\'s forward voltage drop. When a voltage is applied in the reverse direction, the diode begins to breakdown and the current is increased beyond what is normally allowed.

The most important feature of the BZX85B20-TAP diode is that it can absorb a large amount of power when reverse-biased. This is because it has a higher breakdown voltage than most diodes. This feature makes it ideal for power conditioning and filtering applications, where it can absorb and filter out unwanted current spikes.

Another important feature of the BZX85B20-TAP diode is its low-leakage current, which prevents current flowing back through the diode. This is especially important in applications where large currents are present, as it can help prevent damage to the circuit. Its low-leakage also improves efficiency.

Overall, the BZX85B20-TAP is a versatile and reliable device. Its ability to absorb large amounts of power at high voltages, combined with its reverse-leakage and low-power output make it perfect for a variety of applications. It is often used in telecommunications systems, in computers, and in power conditioning and filtering applications.
