Diodes - Zener - Single

DDZ9690S-7 is a type of diode commonly used in electronic circuits as a voltage regulator. It has a wide variety of applications and works on the principle of reverse-biased zener breakdown. The device consists of a single p-n junction diode connected between two terminals and is characterized by the breakdown voltage and the currents that flow through it.

The typical peak reverse breakdown voltage (V_BR) of the DDZ9690S-7 diode is 9.7V, which means that when the voltage on the diode reaches 9.7V, it will break down and allow current to flow through it. This breakdown voltage is the point at which the circuit is regulated and the device will draw a current of 17.5 mA to maintain the voltage at 9.7V. This is known as the regulation current (I_Z).

The DDZ9690S-7 can be used in circuits to regulate the voltage at various points. This works by connecting the diode between the regulated source and a higher-voltage supply. When the voltage at the higher-voltage supply reaches a certain level, the diode breaks down, allowing the current to travel through it and regulating the voltage in the circuit. The circuit can then be adjusted to provide the required voltage at the point where the diode is connected.

The DDZ9690S-7 also has use for voltage-dependent switching. This works by connecting the diode between two separate circuits. When the voltage at the diode reaches the breakdown voltage of 9.7V, current can travel through it and the two circuits will be connected. The amount of current that can travel through the diode is limited by the zener current (I_Z) and the voltage at which the current begins to flow is the breakdown voltage.

The DDZ9690S-7 can be used in a wide variety of applications, from controlling voltage in power supplies, providing voltage-dependent switching, to acting as voltage references in analog circuits. It is an ideal component for circuits where precise control over the voltage is needed, and is also well-suited for applications that require high temperature operation.
