SA10A A0G

TVS - Diodes

Transient voltage suppression (TVS) diodes are special purpose semiconductor components designed to protect other electronic components from voltage-induced damage due to transient overvoltage events, such as those caused by electrostatic discharge (ESD), lightning strikes, and inductive loads. A typical TVS diode is composed of multiple series-connected diodes and a single Zener diode, which acts as a voltage regulator. The TVS diode is therefore able to absorb as much as electronic component can withstand, thereby limiting the surge in voltage.

SA10A A0G application field and working principle

The SA10A A0G is a bidirectional transient voltage suppressor from Vishay Intertechnology. This TVS diode has a stand-off voltage of 8 V, making it appropriate for use in a wide range of applications from automotive, computer, and consumer products, to industrial control and communications systems. The device can also be used to protect applications that are exposed to transient overvoltage events such as lightning strikes, electrostatic discharges, and inductive load switching.

The working principle of the SA10A A0G is as follows. When the TVS diode is subjected to a transient voltage that is greater than the breakdown voltage, the avalanche breakdown effect is triggered, allowing for most of the energy to be filtered away. During this process, the individual diodes in the diode chain are placed in series, forming a low impedance bridge that bounds the current at a safe level. When the voltage exceeds the Zener breakdown voltage, the Zener diode acts as a voltage regulator, limiting the voltage to a given level.

The SA10A A0G offers industry-leading surge current capability of 15 A, low capacitance of 0.2 pF, and a low operating voltage of 5 V. In addition, the device also has a wide operating temperature range of -40 °C to +85 °C, making it suitable for use in a variety of environmental conditions.

In conclusion, the SA10A A0G TVS diode from Vishay Intertechnology is a highly reliable, cost-effective, and efficient device with excellent surge current capability, low capacitance, wide operating voltage, and wide operating temperature range, making it ideal for use in a wide range of transient overvoltage protection applications.
