3EZ6.2D5E3/TR12

Diodes - Zener - Single

3EZ6.2D5E3/TR12 is a kind of Zener diode, which is a diode that utilizes the process of reverse breakdown to operate in the region of negative resistance. It is a single-terminal semiconductor device that is typically characterized by a very sharp reverse breakdown breakdown voltage. Due to this characteristic, 3EZ6.2D5E3/TR12 has some unique applications.

Application Fields

The primary application field of 3EZ6.2D5E3/TR12 is voltage regulation. It is a common component in power supply designs, used in regulating the output voltage of the power supply. It is used to maintain the output voltage at a fixed level, in order to protect from overvoltage or voltage fluctuations. It can also be used in voltage sensing circuit, where the Zener voltage is used as the reference voltage.

3EZ6.2D5E3/TR12 can also be used as a voltage-controlled switch. When connected with a diode, the voltage across the diode is used to control the current flowing through the diode. This can be used in hydroponic systems as a water level switch, where the voltage across the diode is used to control the flow of water.

3EZ6.2D5E3/TR12 is also used in low-current voltage detection circuits. When the input voltage exceeds the Zener voltage, a current will flow through the Zener diode, which can then be used to trigger a switch or a control circuit.

Working Principle

When a voltage is applied to 3EZ6.2D5E3/TR12, an electric field is created across the diode junction. This electric field will cause electrons to flow from the anode to the cathode, allowing a current to flow through the diode. When the voltage exceeds the Zener voltage, the electric field becomes so strong that it can break the structure of the depletion region, causing electrons to flow in the opposite direction, allowing a reverse current to flow. This is called the reverse breakdown voltage.

At the reverse breakdown voltage, the diode exhibits negative resistance. This means that, as the voltage across the diode increases, the current through the diode increases, resulting in a constant output voltage across the diode. The combination of the Zener voltage and the negative resistance of the diode make it ideal for voltage regulation applications.

3EZ6.2D5E3/TR12 is a popular choice for designers due to its ability to be used both as a voltage regulator and as a voltage-controlled switch. The Zener voltage is usually quite low, allowing it to be used in low-current applications, such as voltage detection circuits.
