Diodes - Zener - Single

The CMDZ5236B BK is a zener diode which is designed for applications where assured voltage regulation is important.It is mainly used for voltage reference, voltage clamping devices, voltage regulation, and overvoltage protection in professional electronics.

A zener diode is basically a reverse biased diode which when connected in reverse bias, its breakdown voltage is precisely determined. This process is called Zener breakdown. Zener diode basically line up the electrical characteristics in a graph so that it can be referenced in a specific subject.

Working Principle

A zener diode basically consists of an N-type region joined to a P-type region and connected to a positive and negative voltage source. The flow of current between the positive and negative terminals of the source causes the diode to turn ON once the voltage across it exceeds a certain level. If the voltage across it falls too low, however, the conduction stops, and the diode goes OFF.

When the zener diode is forward biased, the flow of electrons will be from the N-region to the P-region and current can flow in the form of holes and electrons. During this process, the electric potential is equal to the current which is flowing through it and hence the power is constant.

When the zener diode is reversed biased, the electric potential between the two regions jumps to a high value when the anode voltage is increased beyond a certain level. This is known as the zener breakdown and the current that flows through the diode is governed by the zener voltage and the series resistance of the diode.

In the CMDZ5236B BK, the Zener breakdown occurs when the anode voltage is increased to the breakdown voltage of 6.2V which is printed on the diode package. At this point, the current starts to flow in the opposite direction as the electrons are now accelerated by the electric field. The electrons flow through the cathode, thereby creating a regulated minimum voltage drop across the diode and a high load current can be allowed to bypass the diode at this point.

Application Field

The CMDZ5236B BK has the potential to be used in a wide range of applications. It can be used for LED driving, switching power supplies, LCD power supplies, audio amplifiers, and other similar applications. It also has the benefits of being able to withstand high reverse voltages and also to work over a wide temperature range.

The CMDZ5236B BK is a very reliable device and can operate over a wide temperature range from -55°C to 150°C. It can also withstand high reverse voltages up to 400V and the high reliability makes it suitable for long life applications in the telecommunications, automotive, industrial, and consumer electronics.

Another advantage of this device is that it has very low power consumption and low noise generation so it is an ideal choice for applications where low noise and low power consumption are necessary.

Overall, the CMDZ5236B BK is a reliable device which is suitable for a wide range of applications where voltage regulation, overvoltage protection, and other similar applications are required. It has the potential to be used in consumer, automotive, industrial, and telecommunications applications, as well as in audio amplifiers and LCD power supplies.
