Diodes - Zener - Single

Zener diodes form part of the large family of semiconductors known as diodes. As the name suggests, they are made of two closely related components. These components are connected together to form a single circuit. They are typically used as a rectifier in high power circuits such as power supplies, batteries and motor controllers. They can also be used as a voltage regulator.

The main difference between a Zener diode and a normal diode is the reverse breakdown voltage. A normal diode is designed to only allow current to flow in one direction, whereas a Zener diode is designed to allow a small amount of current to flow in both directions. This reverse flow of current is why Zener diodes are also known as ‘regulators’.

The BZV49-C2V4,115 Zener diode is a single diode with a rated reverse breakdown voltage of 115 volts. It has a maximum power dissipation rating of 1.0 W and can operate at temperatures ranging from -40°C to +85°C. The unit also has a maximum reverse current rating at 175 nA. This makes it a suitable choice for power supplies or other circuits containing sensitive components.

The working principle of a Zener diode can best be understood by looking at its diode symbol. The arrow of the diode symbol points in the direction of current flow. When the voltage across the diode is above the reverse breakdown voltage, the diode acts like a normal rectifier, letting current flow in one direction only. This is known as the \'forward bias\' state. When the voltage reaches the reverse breakdown voltage, the diode begins to act like a Zener diode and allows current to flow in both directions. This is known as the \'reverse bias\' state.

The Zener diode is mainly used to control voltage levels in a circuit. For example, it can be used to limit the voltage applied to a sensitive circuit component. It can also be used as a \'clamping\' device for limiting transient voltage spikes. In some applications, the Zener diode is combined with other components such as transistors or resistors to provide additional protection against current surges.

In conclusion, the BZV49-C2V4,115 Zener diode is a single diode with a rated reverse breakdown voltage of 115 volts. It has a maximum power dissipation rating of 1.0 W and can operate at temperatures ranging from -40°C to +85°C. The unit also has a maximum reverse current rating at 175 nA. As discussed, the Zener diode is mainly used for voltage control, clamping and surge protection in circuits.
