DDZ16-7

Diodes - Zener - Single

A diode is a two-terminal electronic device used to either direct or prevent electrical current. Zener diodes, specifically those part of the single diode Zener family, are characterized by low breakdown voltages, which are typically from less than 1 volt to about 200 volts. DDZ16-7 is a single Zener diode used for purposes such as local on module (LOM) protection, line protection and load swell. It offers a unique combination of low leakage current and low series resistance, making it suitable for a variety of applications.

DDZ16-7 application field and working principle

The Zener diode DDZ16-7 is frequently used for applications such as overvoltage protection for automotive electronics, embedded systems and local on module (LOM) protection for communications equipment. Its working principle is based on the reverse-biased breakdown of a p-n junction diode. In this state, the electric field at the junction point is so large that it creates a tunnel across the junction, allowing electrons to tunnel through and conduct current.The most common use of a DDZ16-7 Zener diode is to provide a stable reference voltage to a circuit. When a voltage greater than the breakdown voltage is applied to the diode, the diode becomes forward biased and will draw current. As the voltage across the diode increases, the current through it increases as well, and this increase in current causes the voltage across the diode to remain constant. This constant voltage is known as the ‘Zener voltage’, and it is this property of reverse breakdown that makes the Zener diode particularly useful in circuit protection and reference voltage applications.

The Zener diode DDZ16-7 is specially designed for automotive applications, with its low leakage current and low series resistance making it ideal for line protection and load swell. In automotive applications, the Zener diode acts as a clamping device that limits the voltage applied to the load, protecting it from overvoltage conditions. This is especially important in situations where the input voltage can be subject to wide swings due to temperature variations or changes in engine speed. The Zener diode can also be used to regulate the output voltage of an automotive power supply by providing an accurate reference voltage. By connecting the Zener diode in series with the power supply, the output voltage can be kept at a predefined value and any output voltage fluctuation can be avoided. The Zener diode can also be used to protect sensitive circuits from EMI, as it provides a high frequency shunt path to the ground, suppressing EMI and preventing it from entering the sensitive circuits.

In addition, the DDZ16-7 Zener diode is also used for embedded systems in which it can be used as a voltage regulator. In a regulated power supply, the Zener diode is connected in series with a load, and the load current is limited by the diode. The diode then acts as a voltage regulator, ensuring that the voltage across the load remains constant even when the input voltage changes. This is especially useful in situations where it is not possible to add feedback circuitry. The Zener diode also provides protection against reverse polarity by acting as a short circuit in the case of reversed polarity, preventing damage to the device.

The Zener diode DDZ16-7 is a robust and versatile zener diode, making it useful for a variety of applications. Its low breakdown voltage and low leakages current make it the perfect choice for automotive and embedded system applications, as it can provide overvoltage protection, line protection, load swell, and accurate reference voltage. In addition, its reverse polarity protection and EMI suppressing properties make it ideal for protecting sensitive circuits from external interference. The Zener diode DDZ16-7 is a versatile and reliable device that is an ideal solution for a variety of applications.
