TVS - Diodes (transorb) and their applications are mainly for circuit protection or protection of devices against transient voltage surges, often referred to as Electrical Overstress (EOS). A typical application example is protecting sensitive electronic equipment like communication routers and satellite TV receivers, from lightning surges and other over voltage events.

The SA7.0ARLG is a high-temperature rugged transient voltage suppressor diode specifically designed for sensitive electronic equipment protection against transient voltage surges. It is one type of Transient Voltage Suppression, (TVS) diode which is mainly used to protect sensitive electronic devices from electrical overstress, normally originating from external sources such as lightning, electrical spikes, or static electricity.

The SA7.0ARLG diode has an outside silicon dioxide structure and a low capacitance junction capacitance. Its peak reverse pulse current is much larger than ordinary transistors, which can effectively ensure the protection peak value. The device is AEC-Q101 qualified and RoHS compliant for automotive applications.

The working principle of SA7.0ARLG is simple. When an over voltage occurs, it will quickly conduct, providing immediate protection to the protected equipment. This results in the majority of the surge current being diverted away from the device into the diode, thus providing protection. The diode will limit the voltage seen by the protected device to a safe level. The device will then return to a non-conduction state and await the next transient voltage surge.

Because of its fast response time and wide dynamic range, The SA7.0ARLG TVS diode is suitable for many applications including over voltage transient protection for sensitive electronic equipment like communication routers, satellite television receivers, and other DC powered electronic equipment.

The SA7.0ARLG diode is an ideal solution for protection of sensitive electronic equipment against EOS and USB port protection against over voltage transients. It is also used in the automotive industry to protect sensitive electronic components used in many automotive systems such as engine control modules, navigation systems, airbags, and instrument clusters.

The SA7.0ARLG TVS Diode features a low leakage current, and is optimized for low capacitance and fast response times. This, combined with its high peak current capacity and excellent thermal cycling capability, make it a reliable and robust over voltage protection device suitable for many applications.
