Diodes - Zener - Single is a common application field in electrical engineering, and DDZ9699-7 is one kind of Zener diode in this application field. This article will explain the working principle and application field of this DC components.

A diode is basically an electronic device that allows current to flow in only one direction. It\'s a basically two-terminal semiconductor device in which one of the two terminals called the anode is negative (ground) and the other, called the cathode, is positive (hot). The most common type of diode is a Zener diode. Zener diodes are used to regulate the voltage in electronic circuits. A Zener diode is also an electronic component like an ordinary diode, however the operation of a Zener is reversed so that when a specific reverse voltage is applied, the current through the diode will be controlled and the voltage across the diode will remain constant.

DDZ9699-7 is a specific Zener diode with working range from 9.62 V to 12.18 V, maximum current of 60 mA, a peak reverse power of 350 mW and 5 % tolerance. The maximum average forward current of this device is 15 mA, a maximum surge current of 75 mA and a peak reverse current of 75 mA. When reversely biased, DDZ9699-7 has a relatively high reverse-current until the breakdown voltage is reversed, which makes the voltage across the diode to remain constant.

The most common application of this Zener diode is used as a reference source in a power supply circuit. When DDZ9699-7 is connected in parallel with a current limiting resistor, it can be used to create a reference voltage. This reference voltage can be used as a reference for op-amps, comparators or other functional components. In this application, the maximum power consumed by the diode is proportional to the current used for the reference.

Another common application of DDZ9699-7 is in the protection of a circuit against overvoltage. The diode can be used to protect the circuit from being exposed to excessive voltages, as the Zener diode will keep the voltage across the diode constant. This feature can be used to protect sensitive electronic components from damage caused by overvoltages.

DDZ9699-7 can also be used in the stabilization of voltage sources. By connecting the diode in parallel to the voltage source, the diode will regulate the output voltage level, keeping it constant regardless of the input voltage of the power supply. This feature is also useful for regulating the output voltage of switching regulators, as it can limit the output voltage to a maximum limit.

DDZ9699-7 bipolar Zener diode is a versatile piece of equipment that can be used in a variety of areas, such as voltage regulation and protection of circuits. It can be used to create a stable reference voltage, protect against overvoltage, or even stabilize output voltages. With its features and specifications, it is certainly a device worth looking into.
