Diodes Zener single is an important type of semiconductor diodes, which serves as an electrical current regulator and absolutely prevents any surge of voltage so that the power output remains constant. The DDZ39FQ-7 from Diodes Incorporated is one such example that offers reliable overvoltage protection for applications such as voltage regulator, reference source and reverse transmission protector.

The DDZ39FQ-7 has a zener breakdown voltage of 39V with a 5% tolerance. The breakdown voltage is a type of Zener voltage that refers to the voltage drop upon which a zener diode will be able to pass enough current to stabilize itself. It can also be thought of as the minimum voltage required for the diode to show a sharp decrease in its resistance once it is achieved. Therefore, the breakdown voltage of DDZ39FQ-7 sets it up as an appropriate choice as an overvoltage protection diode in a variety of applications such as voltage regulators, surge protectors and regulated power supplies.

The unit also features a very low reverse current of 20uA which means that the diode is able to pass a minimum amount of current even when there is no external current input signal. This low reverse current maintains the stability of the provided protection and ensures that the voltage output remains optimal even in the event of a surge. Furthermore, the thermal resistance of the DDZ39FQ-7 is R5.5 which also increases its efficacy in Voltage regulation and surge protection in varied applications.

The package for the DDZ39FQ-7 is also very convenient as it comes in a SOD-123F package that offers great thermal and electrical performance in the mentioned applications. The overall dimensions are 0.728" x 0.561" x 0.314". Furthermore, a number of accessories from Diodes Incorporated including the SOT-663 clip and SOT-23 clip are also available that allow for easy mounting of the device in tightly packed circuits. The SOD-123F package also ensures that the device is fully protected against moisture, dust and other elements while allowing for easy handling.

The working principle of DDZ39FQ-7 is also quite simple. In situations where there is a sharp increase in the input voltage, the diode provides an output voltage that remains constant while allowing low power to pass through. This prevents any surge in the output voltage beyond the breakdown voltage by providing the additional current with a path to the ground.

To summarize, the DDZ39FQ-7 Zener diode is an incredibly efficient and cost-effective device for regulating and protecting electrical circuits from any sudden increase in voltage or current. Its low reverse current, excellent breakdown voltage and wide temperature range, along with the high reliability of the SOD-123F package, make it perfect for a variety of applications such as voltage regulators and voltage surge protectors.
