Diodes - Zener - Single: SDZT15R8.2 Application Field and Working Principle

The SDZT15R8.2 diode is a single-chip Zener diode which is especially useful when you need to suppress spikes or voltage surges and regulate a voltage level. This device offers an array of features, including high levels of reverse breakdown voltage, low reverse leakage current, good stability and high efficiency. As such, it is an ideal choice for numerous applications.

Application Field

This type of Zener diode can be used in a variety of applications that require efficient voltage regulation. Its compactness makes it an excellent choice for printed circuit boards, including devices for measuring, control and power conversion. In addition, the device is highly efficient in regulating switching and reverse power applications.

In addition, its low reverse leakage current makes it suitable for circuit protection. This diode can be used in circuits with high reverse voltage consisting of high-speed IGBTs and power MOSFETs. It is also useful in high speed motor drives, frequency inverters and UPS systems, since the device offers the necessary protection while also allowing a smooth startup process.

This type of diode also has applications in military and aerospace electronic systems, where its high levels of resistance to radiation and stable performance in a range of temperatures is appreciated. It can also be used in power supplies or servers, where high efficiency and low energy consumption are desired.

Working Principle

The SDZT15R8.2 is a single-chip Zener diode, which works on the principle of breakdown voltage. It is designed using specialized materials and processes that allow it to behave as a series of successive breakdown levels. This is achieved by creating a series of diodes with different pinch-off voltages.

The device is rated for single-chip operation, meaning that it only needs two points of contact to operate. When the device encounters voltage higher than its rated value, the excess voltage will be blocked and the reverse part of the signal will be directed through the Zener diode. This helps reduce the disruptive effect of voltage spurts and surges, allowing the device to maintain stability.

The device is also designed to allow current to flow either way, making it ideal for use in a bidirectional circuit. When the current flows toward the positive voltage, the reverse voltage is blocked, while the forward-flowing current is directed towards the positive voltage. When the current flows in the opposite direction, the diode works as a protection element, allowing the current to be transferred to a low-voltage side and preventing damage.

Conclusion

The SDZT15R8.2 is an excellent choice for applications that require a high-performance voltage regulator and protection element. This single-chip Zener diode is highly efficient, offers excellent levels of reverse breakdown voltage and reverse leakage current, and features a stable performance in a range of temperatures and conditions. Furthermore, it has numerous applications, from control devices to protection elements, which makes it a great option for many devices.
