Application Field

The DDZ9678Q-7 is commonly used as a voltage regulator in power supplies, since it provides regulated voltages even when exposed to fluctuations in input power. This device has a steep temperature coefficient, which makes it ideal for use in environments with high temperatures or large temperature variations. It is also used in SCR triggering circuits, as it can be used to accurately control the triggering of SCRs. Additionally, this device can be used in any other circuit application requiring precision voltage regulation, such as in logic gates or microprocessors.

Working Principle

The DDZ9678Q-7 employs a Zener diode to achieve its regulation effect. The Zener diode is connected in reverse-biased configuration and acts as a voltage-limiting element. When a voltage larger than the Zener voltage is applied, the diode’s depletion region quickly increases in width and the current passes through it. This results in the voltage at the diode’s output being limited to the Zener voltage. This process ensures the output of the diode to be held at a constant voltage, even when the input power is subject to large fluctuations.

Conclusion

The DDZ9678Q-7 is a single Zener diode. It is commonly used as a voltage regulator in power supplies and SCR triggering circuits, as well as in any other circuit application requiring precision voltage regulation. The diode’s Zener configuration provides a constant voltage output, even when the input power is subject to large fluctuations. The device is available in leaded and surface mount packages, and is constructed using a variety of processes.
