MTZJ24SB R0G Datasheet/PDFMTZJ24SB R0G Application Field and Working Principle
MTZJ24SB R0G is a single zener diode which is used to provide a constant voltage reference. Zener diodes are a type of diode that are designed to allow current to flow in either direction, but when the specified reverse breakdown voltage is reached, the diode begins to sharply reduce the amount of current, thus limiting the voltage drop to a different voltage level.
This MTZJ24SB R0G has breakdown voltage of 24V and can handle maximum powet dissipation of 500 mW. It has low maximum forward voltage drop of 1.1V at rated current, and low reverse leakage current of 1.2µA which makes it ideal for protecting vulnerable circuits from over-voltage and other unwanted current surges. It is suitable for use with complex circuits where a very specific voltage level needs to be maintained, as well as for reset detectors, LED protection, PCBs, and in other similar applications.
Working Principle
The MTZJ24SB R0G is a unidirectional device, meaning that when current passes through the forward direction (anode to cathode), the diode will conduct and allow the current to flow. When current passes through the reverse direction (cathode to anode) the diode will become reverse biased and will not conduct. This is until the reverse voltage reaches a certain point known as the Zener Voltage or Zener Breakdown Voltage.
Once the Zener Voltage is reached, the diode starts to conduct but only in the reverse direction and at a much lower level than the forward direction. This is due to the “Zener effect”, a phenomena discovered by the Swiss scientist, Dr. Claude Zener. When the Zener Voltage is reached, the diode behaves like a resistor and limits the current flow which allows for the voltage to be reduced to a stable, predetermined value.
In the case of the MTZJ24SB R0G, the Zener Breakdown Voltage is 24V, meaning that when an external voltage of 24V is applied, the diode will start to conduct with a much lower reverse voltage. This lower voltage is often referred to as the Zener Voltage and is determined by the device’s specifications. For example, the MTZJ24SB R0G has a Zener Voltage of 24V.
Applications
The most common application of the MTZJ24SB R0G is in protection circuits. It is often used to provide a constant voltage reference, such as in reset detectors, LED protection, PCBs, and other electronic devices. It can also be used as a voltage limiting device, such as in voltmeter circuits or in devices which require a consistently regulated voltage output.
The MTZJ24SB R0G is also well suited for use in power conditioning, power distribution, and other power-electronics applications. Its low maximum forward voltage drop, low reverse leakage current, and high power rating make it perfect for voltage regulation in power conversion systems.
Conclusion
The MTZJ24SB R0G is a single zener diode which is used to provide a constant voltage reference when connected to suitable voltage sources. It is great for use in protection circuits, voltage limiting devices, power conditioning, and other power electronics applications. Due to its low forward voltage drop, low reverse leakage current, and high power rating, it is well suited for voltage regulation applications.
