Diodes come in a variety of different configurations for different purposes. Zener diodes are a special type of diode typically used to regulate power supplies. They are essentially very large diodes with a built-in breakdown voltage, allowing them to safely handle large voltage spikes without risking failure. The SJPZ-K28V is a zener diode used in many different applications, primarily as a power supply regulator.

The SJPZ-K28V is a single zener diode with a breakdown voltage of 28 volts. It is a through-hole package measuring 2.0mm x 1.5mm and is rated for a maximum power dissipation of 300mW. The diode is well-suited for use in both high and low-voltage applications, as well as for applications requiring fast switching speeds. The SJPZ-K28V is available in a variety of packages and is commonly used in automotive, communication, and computer applications.

The most common application of the SJPZ-K28V is in power supply regulation. The diode has a built-in breakdown voltage of 28 volts, which allows it to absorb any spikes in the power supply above this voltage without damaging itself. This makes it ideal for applications where a reliable power supply is necessary, such as in computer systems. In addition, the diode is suitable for use in protection circuits, where it can be used to prevent overvoltage conditions from damaging other components.

The working principle of the SJPZ-K28V is quite simple. During normal operation, the diode acts like an open circuit, allowing current to flow from the supply to the load unhindered. When the voltage across the diode exceeds the breakdown voltage, however, the diode begins to conduct current. This current flows from the supply to the load, thus limiting the voltage across the load to the breakdown voltage. In this way, the diode acts to safely regulate the supply voltage, keeping it within safe limits.

In summary, the SJPZ-K28V zener diode is a widely-used single zener diode with a nominal breakdown voltage of 28V. It is typically used in power supply regulation, protection circuits, and other high- and low-voltage applications. The diode works by acting like an open circuit during normal operation and then conducting current whenever the voltage across the diode exceeds its breakdown voltage, thus safely limiting the supply voltage.
