Diodes - Zener - Single

The DDZ15S-7 is a single Zener diode in a DO-214AA full-pack package that is used to provide a precise and regulated voltage reference. This diode also includes a static protection feature, letting it successfully clamp the voltage generated at the configured levels. It is useful in providing an ultra-stable reference voltage which is required to protect overvoltage or short circuits in circuits, to provide withstand voltage protection of load and power circuits and to connect a digital system where the circuit voltage needs to be defined and/or few current applications such as analog-to-digital converters, high voltage switching and reference voltage for various applications with circuit stability and reliability.

Working Principle:

The working principle of DDZ15S-7 is the same as that of other zener diodes. It features a p-n junction inside, between the anode and the cathode, which exhibits a breakdown voltage known as the Zener voltage. This voltage remains relatively constant, despite the applied DC or pulse current passing through the diode. There is also a characteristic reverse resistance, which is known as the Zener impedance. When a load is connected to the diode, such as resistors or capacitors, the characteristics of the output voltage will depend upon these components. This, in turn, results in a certain level of voltage stability, meaning that despite changes, the output voltage remains constant.

Application Fields:

The DDZ15S-7 is a specific type of Zener diode, and as such, it provides precisely adjustable, frequently-used voltage references for many applications. It is thus used in a wide range of designs, with the details so specific that it is sometimes the only device that can provide the necessary voltage or current. DDZ15S-7 is commonly employed in electric current control applications, including analogue-to-digital converters, high-voltage switching and regulated reference voltage circuits, as well as other precision and dynamic resistor circuits. It is also applicable in audio equipment, and as an overvoltage protection element. In some cases, dynamic protection elements are used in conjunction with DDZ15S-7 to provide stable, dynamic surges and shorts protection.

Advantages:

The biggest advantage of using DDZ15S-7 is its ability to maintain the output voltage and current at a stable and predefined level, regardless of the load connected to it. This makes this device perfect for applications requiring dependable, reliable and accurate voltage and current control. Additionally, it is an efficient diode because it has a very low forward voltage drop, making it ideal for applications that require high efficiency. Its high breakdown voltage makes it suitable for applications with very high operating voltages. It is also a low-cost device, making it an attractive option for use in many designs where cost is a primary concern.
