• DZ2724000L Application Field and Working Principle

The DZ2724000L is a Zener diode manufactured by Diodes Incorporated and meant for surface mounted applications (SMT) in electronic assemblies. This type of diode is a widely used device in many electronic circuits, playing a vital role in controlling power and sometimes used as a device for circuitry protection and stabilization. Normally, Zener diodes are used in reverse-biased conditions, which means that the current flows in the opposite direction than when forward biased. Generally, the capacitor can operate at maximum breakdown voltage of 27 V with a power rating of 500 mW and a narrow tolerance level of 5%.

Zener diodes are built with a P-N junction that consists of semiconductor materials like gallium-dioxide (Ga2O3) or silicon (Si). These materials are used because they can hold an electrical charge and be switched between a forward-biased and a reverse-biased condition. The most important characteristics of the DZ2724000L are the avalanche voltage (Vz) breakdown and the power rating. The former determines the maximum voltage a diode can withstand before it begin releasing the electrical charge. The power rating determines the maximum amount of current the diode can process.

The use of Zener diodes prevents the overvoltage circuits from facing damages due to circuit short caused by excess current. The Zener diode allows a current to flow only in one direction and when the flow is reversed, it blocks the flow. This makes it ideal for reverse voltage protection since it enables the circuit to absorb excess charge and release it back into the circuit without actual damages to the machine. Moreover, the current limiter enables the device to remain in an ideal operating condition.

The Zener diode that is used commercially in modern circuits have become more stable with their accurate and consistent regulation circuitry. This enables the DZ2724000L to act as an ideal voltage reference for maintaining a predefined voltage level in electronic circuits. In order to provide voltage regulation, a Zener diode is connected in parallel to a resistor connected to a current so that Zener diode provides a reference voltage and the resistor limits the amount of current in the circuit. When the voltage level increases above the Zener diode\'s breakdown voltage, the diode lets the current flow in the reverse direction, releasing the excess amount of energy.

The DZ2724000L is an ideal choice for voltage regulation, voltage clamping and as a reference voltage source. It can be used in power corded and power cords each, power supplies, DC-DC converters, analog to digital converters, transistors, laser diodes, LED\'s and static protection circuitries. Application engineers should have a basic understanding of the characteristics and working principles of the diode in order to prevent damage to the equipment when the diode is in a reverse current mode.
