PZU11B2,115 diodes, otherwise known as Zener diodes, are single diodes known for their ability to provide a constant voltage output in the face of voltage surges, spikes and noise. It has a wide range of applications, from meeting the needs of industry-standard specifications for power supplies to protecting sensitive components from power surges. To understand how the PZU11B2,115 works, it is necessary to understand the working principle of Zener diodes.

The semiconductor material of a Zener diode includes N-type and P-type materials. Under normal operation, the voltage at the junction of the two terminals of the diode is 0V. If a reverse voltage is applied to the diode, electrons flow from the P-type material to the N-type material, creating a potential difference between the two terminals - the Zener voltage, Vz. The higher the Zener voltage, the more electrons will flow between the terminals, causing current to pass through the diode. This current is known as a Zener Current, IZ. The IZ is generally very small and does not cause significant heating in the diode.

PZU11B2,115 Zener diodes are designed to be driven by a reverse biasing voltage, which will cause the diode to become reverse conducting and allow a very small leakage current to flow. The PZU11B2,115, in particular, is designed with a Zener voltage of 11.5V and a reverse breakdown voltage of 12.5V. The operating temperature range for the PZU11B2,115 is -55°C to +125°C.

PZU11B2,115 Zener diodes are primarily used in the design and assembly of linear power supplies. They are also used to provide a stable voltage source to stabilize the output voltage of voltage regulator components. When connected in parallel with an AC power line, they act as overvoltage protectors, regulating the line voltage and improving the system\'s reliability.

The PZU11B2,115 can also be used in conjunction with other components to provide circuit protection against short duration, high voltage transients. This is accomplished by using the PZU11B2,115 in series with a transient voltage surge suppressor. When connected in this manner, the transient voltage surge suppressor will be the first to respond to voltage spikes, and the Zener diode will kick in if the surge is longer in duration.

Finally, Zener diodes like the PZU11B2,115 are sometimes used as voltage reference elements in the design of operational amplifier circuits. When used in this way, the Zener diode can provide a very stable, low-noise reference voltage for the op-amp circuit, resulting in improved accuracy and performance.

In summary, PZU11B2,115 diodes, a single diode type, are versatile components with a wide range of applications. They are resistant to voltage surges, spikes and noise, and can be used in the design and assembly of linear power supplies, as overvoltage protectors, in conjunction with other components to provide circuit protection against short duration, high voltage transients, and as voltage reference elements in operational amplifier circuits.
