3EZ4.3D5RLG Application Field and Working Principle

The 3EZ4.3D5RLG is a Zener diode from the 3EZ series of semiconductor products. Like all Zener diodes, this device is used for a variety of circuit protection and voltage regulation purposes. It is a single diode that consists of a cathode and an anode with a reverse-biased breakdown voltage of 4.3 D. This diode is manufactured with two array packages that are available for use in space-conserving designs and has a modest maximum power dissipation.

The breakdown voltage of a Zener diode is the voltage at which the device begins to conduct current in the reverse direction. This means that current will flow from the anode to the cathode instead of the other way around. The current flowing through the device will cause a voltage drop across it, and thus regulating the output voltage to be equal or close to the breakdown voltage of the diode. This makes Zener diodes an excellent choice when looking to provide a regulated voltage source with stable output.

As a result of its functionality, the 3EZ4.3D5RLG is widely used in a range of voltage-regulation applications. This includes providing stabilized power supplies for circuitry that is sensitive to input voltages, providing over-voltage protection for sensitive components, such as microcontrollers and other integrated circuits, stabilizing the output of a voltage divider circuit, and preventing voltage surges from damaging electrical components.

The current-limiting resistor values required for a Zener diode circuit can be found in the datasheet for the particular model. In the case of the 3EZ4.3D5RLG, the datasheet will provide a minimum and maximum current through the device and a minimum and maximum resistor value for the circuit. These values can be used to choose the right resistor for the particular application, ensuring that the components are used within the safe operating limits.

When reverse biased, the 3EZ4.3D5RLG has a maximum Zener impedance of 10 ohms. This means that a voltage drop of less than 10 volts is required for the device to begin conducting. The current flow through the device is also limited, which helps to protect the device and the rest of the circuit from a sudden surge in current. Additionally, the 3EZ4.3D5RLG also features a modest maximum power dissipation rating. This dissipation rating should not be exceeded in the application, as it can cause the diode to become damaged or even destroyed.

In summary, the 3EZ4.3D5RLG is a single Zener diode that can be used in a wide range of voltage-regulation applications. The datasheet will provide all the necessary values for the design of the circuit. Additionally, the device should also be randomly tested for specification compliance before it is deployed in a system. Taking these precautions will ensure that the diode functions correctly and efficiently for a long time.
