Diodes - Zener - Single

The 2EZ20D10E3/TR12 is a Zener diode, a type of diode manufactured specifically for its breakdown voltage characteristics. In essence, it allows current to flow in only one direction, and laterally breaks down when the voltage across it is greater than a specified breakdown voltage. It is a single diode, meaning it has a single anode and cathode terminal and is encased in a plastic package.Due to its ability to limit voltage, the 2EZ20D10E3/TR12 is very useful in many applications, in particular for applications requiring precision voltage measurement and display. For example, it can be used as an input and output voltage protection device, protecting sensitive electronic components from dangerous electrical voltages. Additionally, since the 2EZ20D10E3/TR12 can handle high continuous voltages, it is often used for large scale industrial applications such as lightning arresstors and power transformers.The working principle of the 2EZ20D10E3/TR12 is relatively simple. When an applied voltage is below its breakdown voltage, the diode will behave like an open circuit, effectively blocking current flow. However, when the voltage across the diode is greater than its breakdown voltage, the diode will “break down” and current will flow through it. The amount of current flowing through the diode depends on the size of the applied voltage, with higher voltages allowing more current to pass.As the current flowing through the diode changes, the current flow quickly heats up the inside of the diode. As a result, this causes the voltage across the diode to increase, keeping the applied voltage at a manageable level. This temperature-dependent process is known as temperature compensation and helps to stabilise the diode’s breakdown voltage.In summary, the 2EZ20D10E3/TR12 is a single Zener diode with excellent breakdown voltage characteristics, making it an ideal choice for applications requiring precise voltage regulation. As well its breakdown voltage can be stabilised through temperature compensation, allowing it to work reliably in even the harshest of environments.
