DDZ28-7

Zener diodes are a specific class of diodes that are designed to operate in the breakdown or “Zener” region. A DDZ28-7 is a particular type of Zener diode that is designed to operate at a breakdown voltage of 28 V and a maximum power dissipation of 0.5 W.

A Zener diode\'s most common application is for voltage regulation. While a normal diode can only allow current to travel in one direction, a Zener diode is capable of allowing current to travel in both directions. This means that when the voltage across the diode exceeds the breakdown voltage, the diode will “break down” and allow current to flow in both directions, effectively regulating the voltage to the desired value. This makes the Zener diode an essential component in regulating the output voltage of power supplies and voltage regulators.

A DDZ28-7 is ideal for use in circuits requiring a 28V voltage regulator. When using the DDZ28-7 as a voltage regulator, a minimum load of 0.1 mA must be applied to the diode in order for it to work correctly. This is done by adding a load resistor or a load capacitor in parallel with the diode. In addition, the diode must have adequate power dissipation, so a heat sink should be added to the diode to dissipate heat. The diode should also be protected from input overvoltages using a series resistor.

In addition to voltage regulation, Zener diodes can also be used to protect sensitive electronic components from overvoltage transients. When the input voltage exceeds the breakdown voltage of the diode, the diode will break down and allow current to flow in both directions, safely shunting excess voltage away from the protected components.

The DDZ28-7 Zener diode is an incredibly versatile component that can be used in a wide variety of applications, such as voltage regulation and transient suppression. With its 28V breakdown voltage and 0.5W power dissipation rating, it is an ideal choice for applications requiring a 28V voltage regulator.
