TVS - Diodes

Transient Voltage Suppression (TVS) diodes are used for protection against transient voltage spikes. The main type of TVS diodes is the QZX563C6V8C-7. It is a fast bi-directional single-line unidirectional (unipolar) device for surge protection. It has been designed for ease of implementation in a wide range of high-pressure and low-pressure applications. This article will discuss the QZX563C6V8C-7\'s application field and working principle.

Application Field of QZX563C6V8C-7

The QZX563C6V8C-7 is mainly used to protect sensitive components and applications such as low-power logic circuits, microprocessors, radio frequency (RF) circuits, and computers from the effects of static electricity, over voltage, and lightning strikes. It can protect against up to six-kV of surge (surge capability), and has a clamping voltage of less than eight-kV. The QZX563C6V8C-7 has an effective clamping of 1ma down to 0.2ma, with an ultra-low capacitance of 28pF.

The QZX563C6V8C-7 is ideal for protecting systems that require high reliability in all applications. It has a wide operating temperature range from -55°C to +125°C, with a surge capability of up to 6kV. The device is designed to provide superior protection to sensitive components, even in harsh environments.

Working Principle of QZX563C6V8C-7

The QZX563C6V8C-7 utilizes a Zener diode to protect against the effects of transient voltage spikes. The Zener diode is responsible for absorbing the high voltage and preventing it from being applied to the sensitive components of the system. In order to protect the system from sustained high voltage, an avalanche breakdown process is triggered within the Zener diode, which induces a high current flow to the protected component. This current flow then dissipates the voltage to a safe level.

In addition, the QZX563C6V8C-7 is designed to provide fast response times in order to protect the system from transient surges. The device has a fast switching action which reduces the time that the transient surge is present. This helps to reduce the amount of damage to the system and minimizes downtime.

Conclusion

The QZX563C6V8C-7 is an ideal choice for protection against transient voltage spikes. It is suitable for a wide range of applications and has an operating temperature range from -55°C to +125°C. The device utilizes a Zener diode and an avalanche breakdown process to protect sensitive components from the effects of voltage surges. The QZX563C6V8C-7 also has fast response times, which helps to reduce downtime and damage to the system.
