It is used to limit voltage across integrated circuits, prevent short circuits, and provide protection for sensitive components. In automotive applications, this diode is used for controlling DC power, driving LEDs, and other automotive control applications.

Working Principle:

The BZT52B75-E3-18 is a Zener diode, which uses a voltage breakdown effect to regulate the voltage across the diode. When a forward or reverse bias is applied, current will start to flow through the diode, and when the voltage across the diode exceeds a certain level, the diode will "breakdown" and the current will spike. This breakdown occurs at the Zener breakdown voltage, which is usually around 18V for the BZT52B75-E3-18 diode. The diode will then dissipate the excess current and keep the voltage across the diode at this breakdown voltage.

The BZT52B75-E3-18 diode also has a low reverse leakage current. When the voltage across the diode is below the breakdown voltage, there will still be a small amount of current flowing through the diode. This current is known as the leakage current, and it is typically very low for this diode. This leakage current is important for the protection of the components in the circuit, as it will prevent any short circuits.

Overall, the BZT52B75-E3-18 diode is a low-cost and reliable solution for voltage regulation and protection in automotive, consumer electronics, and power supply applications. Its low leakage current and high stability make it an ideal choice for use in harsh environments, while its high voltage rating ensures reliable performance.
