DZ2J02700L Datasheet/PDFDZ2J02700L is single Zener diode, a type of semiconductor device which consists of a junction between two types of semiconductor material. It employs reverse breakdown to allow current to flow in a direction opposite to that of the usual current flow through a forward-biased diode. This reverse current flow will occur when the voltage at the diode\'s cathode is equal to the breakdown voltage of the diode.
The DZ2J02700L is used for voltage regulation, specifically in applications where a given voltage needs to be maintained. When used in this kind of application, the DZ2J02700L will monitor the voltage across it, and will regulate the voltage level present at the diode. If the incoming voltage is higher than the breakdown voltage of the diode, the DZ2J02700L will draw current from the incoming power source, reduce the voltage and push this regulated voltage across the device.
The work principle of a DZ2J02700L is as follows: when the reverse voltage applied to the diode is lower than the established Zener voltage and positive voltage is applied to the diode, current flows through the diode just like a normal diode. If the forward voltage on the diode exceeds the Zener voltage, a reverse circuit phenomenon is triggered and current flows through the diode in the opposite direction, allowing the voltage across the diode to remain at a constant reference level.
DZ2J02700L can be widely used in the circuit for voltage regulation, overvoltage protection and frequency control, etc. It can be used as the stabilizer of voltage samplers and amplifiers, often installed on the same power supply line. It can also be used as temperature compensation elements, on-board sound cards, transistor drive circuits in household appliances, overvoltage protection circuits for communication equipment, logic control circuits for electronic gaming machines, and switching frequency control of inverters.
In addition, The DZ2J02700L is useful for protecting the equipment from overvoltage, the overcurrent and the overvoltage situations by employing diode in parallel with the load device. This can be achieved by connecting the diode at the output side of the power supply line and while its cathode end is connected to a low impedance load. Thus, when the overvoltage is reached by the power supply source, voltage undergoes reverse-bias, creating a closed loop current flow and sensing the voltage across the diode to protect the underlying load device.
To conclude, the DZ2J02700L is a single Zener diode which finds a lot of applications in voltage regulation, overvoltage protection and frequency control. It is triggered by a reverse circuit phenomenon when the forward voltage on the diode exceeds its Zener voltage, generating a current flow in the opposite direction and allowing for the voltage across the diode to remain at a constant level.
