2EZ82D5/TR8 Diodes - Zener - Single Application Field and Working PrincipleThe 2EZ82D5/TR8 is a Zener Diode, which is an electronic component used for producing constant voltage. It was developed by two German physicists, Dr. Ferdinand Braun and Karl Ferdinand Braun, in the early twentieth century. This diode is made of a semiconductor material and uses the Zener effect to regulate the reverse-bias voltage, protecting components from voltage surges. A Zener diode is designed to have a breakdown voltage that is predictable and constant. A Zener diode is a voltage-regulating device that allows a greater current to flow in the reverse direction than in the forward direction. When a current passes through a diode in the forward direction, it is blocked by the diode. Button in the reverse direction, the diode allows a specific amount of current to flow. For 2EZ82D5/TR8, this reverse voltage can be as high as 8.2V. If the current tries to exceed the value at which the Zener diode is specified, then the Zener diode will “break down” and prevent the current from flowing. This “break down” is exactly what makes the Zener diode useful as a voltage regulator. The basic structure of a diode includes a semiconductor material sandwiched between two electrodes, typically made of either metal (silver or gold) or graphite. In a Zener diode, when the reverse-bias voltage reaches a certain level (the Zener voltage), the schottky barrier of the diode breaks down, allowing current to pass through it in reverse. This is the Zener effect. 2EZ82D5/TR8 is a single diode, meaning it is constructed with a single P-N junction. This single junction enables it to withstand reverse bias voltages up to 8.2V and block current of up to 65mA, depending on the application. Its high usage as a voltage regulator makes the 2EZ82D5/TR8 a popular choice amongst electrical engineers, hobbyists and even current suppliers. 2EZ82D5/TR8’s application fields include: voltage regulation in circuits, protection against current surges, powering up noncritical circuits, and many more. Additionally, it is used in many everyday applications, such as in LED lights, mobile phone chargers, electronic circuits, and other electronic devices. The 2EZ82D5/TR8’s working principle is based on the Zener effect, a phenomenon in which the voltage across a reverse-biased P-N junction rises to a very high value when the reverse bias voltage reaches the Zener voltage. This high voltage stops the current from passing through the junction and the Zener diode prevents the current from exceeding the specified value. This process is useful for controlling the amount of current passing through a circuit and is used in applications such as voltage regulation. To sum up, the 2EZ82D5/TR8 is a Zener diode that is used to control the amount of current passing through a circuit and is used in many applications. It is a single diode and its reverse voltage can reach 8.2V. Its application fields include voltage regulation in circuits, protection against current surges, powering up noncritical circuits and many more. Its working principle is based on the Zener effect and it is a popular choice among electrical engineers, hobbyists and current suppliers.
