TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are devices capable of withstanding and limiting high voltage and surge current. These diodes limit the circuit and component damage caused by such events by clamping the voltage below the predefined peak voltage limit of the device. The SA10CAHR0G is a Zener diode, which is one type of TVS diode, and its application field and working principle are as follows.

Application Fields

The SA10CAHR0G is an ideal device for use in low voltage systems and provides protection in a variety of portable electronic applications, including notebook and tablet computers, cellular phones, personal digital assistants, and other communication devices. Due to its high peak pulse power rating of 4.5 kV and small, low-profile surface-mount package, the SA10CAHR0G is especially well-suited for designing and protecting an interface circuit between systems with different voltages.

Working Principle

TVS diodes work by clamping transient voltages to a defined voltage level that is typically less than the system\'s power supply. The SA10CAHR0G works precisely in the same way. When the input voltage exceeds the diode\'s breakdown voltage, its current rating is greatly increased and it acts as a low resistance shunt, clamping the voltage to the diode\'s breakdown voltage. The SA10CAHR0G is a 5.6V Zener diode with a maximum clamping voltage of 7.2V and a maximum leakage current of 10μA. In addition, its short-circuit current rating is 6A and its dynamic resistance is typically 0.3Ω. Thus, when an over-voltage surge occurs, the SA10CAHR0G will protect the system from being damaged by clamping the voltage to the diode\'s breakdown voltage.In summary, the SA10CAHR0G is a Zener diode, a type of TVS diode used for protecting low voltage systems by limiting the voltage and preventing damage caused by over-voltage surges. It has a high peak pulse power rating and a low-profile, surface-mount package, making it ideal for use in a variety of portable electronic applications. When an over-voltage surge occurs, the SA10CAHR0G will protect the system by clamping the voltage below the breakdown voltage.
