PZU7.5B2,115

Diodes - Zener - Single

Diodes with Zener Breakdown are widely used in many electronic applications that require a low power control of flow current. This type of diode is designed to allow current to flow through it when the voltage applied to them reaches a certain point known as the Zener Breakdown or Zener Voltage. The PZU7.5B2,115 is a type of single Zener diode which has been designed to have a Zener breakdown voltage of 7.5 volts and an operating current of 115 mA.

What is Zener Breakdown?

Zener breakdown is the phenomenon that occurs when a diode is subject to a reverse voltage high enough to exceed its breakdown voltage. This breakdown is caused by the electrons that form the depletion region becoming highly energized and having enough kinetic energy to cross the potential barrier. This reverse breakdown voltage is limited by the PZU7.5B2,115\'s doping concentration, so the peak current remains limited to a current of 115 mA.

Applications

The PZU7.5B2,115 is a Zener diode and can be used in many applications such as protection from overvoltage, over current and reverse current protection, voltage regulation and even as a precision voltage reference. It can be used as a simple voltage regulator for low current applications. For example, if a voltage source needs to be regulated to 7.5 volts, the PZU7.5B2,115 can be used to achieve that. The diode can also be used as a voltage reference in a circuit, since it has a precise breakdown voltage and will not drift with temperature or current variations.

Working Principle

The PZU7.5B2,115 Zener diode consists of two elements: an anode and a cathode. When the PZU7.5B2,115 is forward-biased, that is, with the anode connected to the positive side of the voltage source and the cathode connected to the negative side, current will flow through the PZU7.5B2,115. As the voltage is gradually increased, it eventually reaches a certain point, which is the Zener breakdown voltage of 7.5 volts. When this is reached, a small current begins to flow through the PZU7.5B2,115 in the reverse direction. This causes the electrons in the depletion region of the diode to become highly energized and break through the potential barrier of the diode, resulting in a sudden increase in current. This current is limited by the doping concentration of the PZU7.5B2,115 to a maximum of 115 mA.

The PZU7.5B2,115 Zener diode is a useful tool for many applications, due to its precise breakdown voltage, rugged design and low power consumption. It can be used in many devices, such as voltage regulation applications and precision voltage references. Its working principle is simple and easy to understand and is an ideal choice for low current applications.
