Diodes - Zener - Single

Zener diodes are a type of diode that is designed to allow current to flow in either direction. They are most commonly used as a voltage regulator, allowing current to flow in the reverse direction when a certain voltage has been reached. Zener diodes are also often used in amplifier circuits as a protection from overvoltage.

The BZV55-C2V4,115 is a single-junction, glass-encapsulated Zener diode. It has a maximum peak reverse voltage of 200 volts and a nominal Zener voltage of 4.5 V. It has a Maximum Zener Impedance of 1.0 Ohm. It also has a power dissipation rating of 115 mW.

Application Field

The BZV55-C2V4,115 diode is commonly used as an electronic voltage regulator. It typically works by allowing current to flow in the reverse direction at a specific voltage. This helps to maintain a constant output voltage even when the input voltage changes. It is commonly used in consumer electronics such as portable audio players and handheld gaming systems.

The BZV55-C2V4,115 diode can also be used in amplifier circuits as a protection from excessive voltage. It serves to limit the voltage in the circuit, helping to prevent damage from happening. In some cases, the diode may be used to protect the circuit from reverse voltages.

Working Principle

The BZV55-C2V4,115 diode works by allowing current to flow in both the forward and reverse directions. When the voltage across the diode is below the Zener voltage (4.5 V in this case), the diode acts like a normal diode, allowing current to flow in the forward direction only. However, when the voltage reaches or exceeds the Zener voltage, the diode then allows current to flow in the reverse direction, allowing excess voltage to pass. This helps to maintain a constant output voltage.

The diode also has a maximum power dissipation rating of 115 mW. This means that even when the voltage reaches its Zener voltage, the diode will only allow a certain amount of current to flow, to ensure that it does not exceed the rated power dissipation. This helps to protect the diode from damage due to excessive current.

The BZV55-C2V4,115 diode is a simple yet effective device, used to maintain a constant output voltage in the presence of varying input voltages. It is commonly used in consumer electronics and amplifier circuits as a protection from overvoltage.
