The PDZ27B,115 Zener diode is a single-junction diode designed to provide a current–regulated power source. It is a three-terminal, P-N-junction device constructed from a heavily doped N-type and a less-heavily doped P-type semiconductor material.
The working principle of the PDZ27B,115 is based on the fact that when a forward voltage is applied, the electrons in the N-type region create a depletion region in the P-type region and that current flow occurs meaning the diode starts to conduct a current. From this point forward, the diode will start to regulate the current if the voltage applied to it is higher than the Zener voltage, VZ, of this diode, which has a value of 27 V.
Once the voltage is higher than the Zener voltage, the current flowing through the diode begins to increase exponentially, following an inverse exponential curve. This is known as the reverse breakdown or Zener effect and it is this break down that is used to provide a regulated output voltage.
This Zener series of diodes has many uses, most commonly as a voltage regulator in electronic circuits. It is also used as a protection diode, as it limits the voltage applied to the circuit, by diverting excess voltage away, and protecting the circuit from damage. Additionally, it can be used to limit the amplitude of a signal or to rectify a signal.
Other applications of the PDZ27B,115 include voltage clamping, voltage shifting, surge absorption and noise suppression. By inserting a Zener diode between two nodes, it is possible to limit the voltage between the nodes to the Zener voltage, effectively clamping the voltage.
Moreover, the ability of the PDZ27B,115 to regulate a current means it can also be used in voltage shifting circuits. This enables it to move or shift a signal or voltage from one level to another, or from one range to another. It can also be used to absorb unwanted surges or spikes in voltage, by diverting the extra voltage away from the primary circuit.
Finally, the PDZ27B,115 can be used to reduce the amount of generated electromagnetic interference (EMI) and radio frequency interference (RFI). This is done by inserting the diode into the signal path of the circuit that is generating the interference, which limits the noise and prevents it from reaching the signal line.
In conclusion, the PDZ27B,115 is a three-terminal, N-P-junction diode designed to provide a current-regulated power source. It is commonly used as a voltage regulator and protection device, in order to limit the voltage between two nodes and prevent damage to the circuit. It can also be used in voltage shifting, surge absorption and noise suppression applications.
