TVS - Diodes

Transient Voltage Suppression (TVS) diodes are an essential component in protecting sensitive electronic circuits and they are used regularly in many different applications. The SA170CAHB0G is a particular type of TVS diode that has a wide range of uses in different electronics. In this article, we will learn about the application fields and the working principle of the SA170CAHB0G.

Application Fields

The SA170CAHB0G is commonly used as a form of protection on printed circuit boards (PCBs). It is able to provide effective over-voltage protection for different types of circuitry, such as integrated circuits and high-powered components. It can also help to protect circuitry from static discharges or common surges that are caused by external sources, such as lightning.

Furthermore, the SA170CAHB0G has a multi-purpose role in some mobile and computer equipment. It is commonly used in components for PC motherboards, laptops, cell phones, tablets and other devices. This makes it a useful choice for devices that may be exposed to environmental stresses, as it helps guard against electrostatic discharges and other disturbances.

Working Principle

The SA170CAHB0G is a uni-directional diode, meaning that it is designed to only allow current to pass through it in one direction. When there is an over-voltage surge, which occurs when the voltage goes above a certain level, the diode is triggered and conducts current, thereby providing effective protection.

The diode has a peak pulse power rating of 500 watts and can handle surges of up to 2.2kV in terms of peak pulse. The device also has an excellent performance in terms of capacitance, which is linked to the speed at which the diode conducts current. The lower the capacitance, the faster the diode can respond to an over-voltage surge and the better the protection it provides.

Conclusion

The SA170CAHB0G is a valuable TVS diode that is able to effectively protect sensitive electronic circuits from damage caused by transient over-voltage surges. For its small physical footprint, it is able to offer excellent levels of protection with a high speed response and a peak power rating of 500 watts.
