A diode is a semiconductor device composed of at least two terminals, usually made of an anode and a cathode, that is used to control the flow of electric current. Diodes are traditionally used to rectify alternating current into direct current, but they can also be used in a variety of other ways, such as to control the flow of current in a circuit, to protect components from voltage, and to protect the power supply from voltage spikes. One of the most common diodes is the Zener diode, which is used to regulate voltage in a circuit. The 3EZ7.5D2E3/TR8 is a single Zener diode that has a working voltage of 7.5V and a maximum power dissipation of 500mW.

Application Field

The 3EZ7.5D2E3/TR8 Zener diode is used in a range of electronic applications, including power supplies, battery chargers, audio amplifiers and HF impedance matching circuits. It can also be used in voltage clamping circuits to protect components from over-voltage, and as a voltage reference in voltage regulation circuitry.

Working Principle

The 3EZ7.5D2E3/TR8 Zener diode operates on a reverse bias configuration, meaning that the anode is connected to ground and the cathode is connected to a higher potential than ground. The diode is said to be "forward biased" when it is operating normally, meaning that the anode is connected to a higher potential than the cathode. When the current flowing through the diode reaches a certain level, the diode operates on a "reverse breakdown voltage," meaning that the potential across the diode is forced to become greater than the forward bias potential.

When the voltage across the diode reaches that level, it begins to conduct current in both directions, allowing it to regulate the voltage in the circuit. This principle is commonly known as "Zener breakdown," which is the basis of a Zener diode\'s voltage regulation capabilities. The breakdown voltage is determined by the materials used to construct the diode and can be precisely selected to achieve the desired output.

The 3EZ7.5D2E3/TR8 Zener diode can be used in both low voltage and high voltage applications. For low voltage applications, the diode can be used to regulate voltages of up to 7.5V, while for high voltage applications, the diode can be used to regulate voltages up to 40V. The 3EZ7.5D2E3/TR8 is also capable of dissipating up to 500 mW of power, making it suitable for a variety of power supply applications.

In conclusion, the 3EZ7.5D2E3/TR8 is a single Zener diode that can be used in a wide range of electronic applications. It has a breakdown voltage of 7.5V and a maximum power dissipation of 500 mW, making it suitable for both low and high voltage applications. Additionally, its Zener breakdown principle enables it to precisely regulate the voltage in a circuit and protect components from over-voltage.
