Diodes - Zener - Single: 2EZ9.1DE3/TR12 Application Field and Working Principle

Diodes are electrical components with two-way conductive properties. Zener, which is a type of diode, stands out because of its unique mode of action compared to other diodes. Zener diodes, like the 2EZ9.1DE3/TR12, are often used to regulate power in electronics. This article will explain the application field and working principle of the 2EZ9.1DE3/TR12.

Application Field

The 2EZ9.1DE3/TR12 is a silicon Planar Zener diode. It is particularly useful in applications that involve power regulation, such as in switched-mode power supplies and voltage regulators. This Zener diode is great for regulating voltage in circuits, as it is able to past through a large amount of current while still controlling the output voltage. The Zener diode is also great for protecting against overvoltage in circuits. The 2EZ9.1DE3/TR12 can be easily used in circuits due to its low power dissipation rating. The diode is able to pass currents up to 500 mA and can withstand voltages up to 25 V.

Working Principle

A Zener diode is called a "voltage-controlled variable resistor" because it is used to regulate voltage in a circuit. The diode behaves like a resistor except when the voltage across it is higher than the Zener voltage. The Zener voltage is the breakdown voltage at which the Zener diode starts to conduct. When the voltage across the Zener diode is higher than the Zener voltage, the diode will start to conduct heavily and it behaves like a short circuit. This allows voltage to be regulated in the circuit. The Zener diode will control the voltage by blocking excess voltage and only allowing current to flow through it when the voltage reaches the Zener voltage.

The 2EZ9.1DE3/TR12 is a single-terminal voltage regulator diode. This means that it only has one lead connected to the anode, while the cathode is connected to ground. The single-terminal Zener diode is also great for protecting circuit components from overvoltage. The Zener diode will conduct heavily when the voltage across it reaches its breakdown voltage, limiting the current that flow through the circuit and protecting other components from damage. The 2EZ9.1DE3/TR12 can withstand a maximum voltage of 25 V and can pass currents up to 500 mA.

The 2EZ9.1DE3/TR12 is a versatile Zener diode that is great for regulating voltage in circuits. The Zener diode has a maximum voltage rating of 25 V and can pass currents up to 500 mA. It can also be used to protect against overvoltage in circuits, preventing damage to other components. This Zener diode can be easily used in applications that involve power regulation, such as in switched-mode power supplies and voltage regulators.
