TVS diodes, commonly referred to as Transient Voltage Suppressors (TVSs), are designed to protect electronic components from transient overvoltages such as electrostatic discharge (ESD), lightning strikes, and switching transients. The SA20ARLG is an ultra-low capacitance ESD protection diode array that is capable of protecting high-speed signal lines from voltage transients caused by ESD and other electrostatic discharges. It is a two-channel device compatible with 1.8V, 2.5V, and 3.3V systems.

The SA20ARLG is ideal for applications in which space is limited, such as on printed circuit boards (PCBs) in computing, communication, and consumer electronics. It offers excellent surge eradication capability even in the most hostile environments. This device includes a reverse ESD protection circuit for maximum reliability and provides a high level of protection against ESD events.

The SA20ARLG is constructed of silicon chips and consists of two diodes that are connected in series. Each of the two diodes has an independent channel. The diode on each channel has a low reverse leakage current and a low reverse breakdown voltage. The diode arrangement allows the device to limit the voltage between the two channels to a maximum of 1.6 volts.

The SA20ARLG working principle is based on the voltage-clamping effect of a reverse biased p-n junction diode. When a transient voltage is applied, the diode is forward-biased and the resulting current (charge) is conducted through the diode. The diode clamps the voltage to a level determined by the junction voltage and the current that can be conducted through the diode.

The SA20ARLG can dissipate surges that are ideally measured in the typical range of 1 - 8 kV. It is designed to protect high-speed, low-voltage signal lines from ESD events and is also capable of providing high-level ESD protection to signal and control lines. The SA20ARLG features a low capacitance design with a working frequency of over 1GHz, and can handle up to 100V ESD pulse.

In conclusion, the SA20ARLG is an ideal choice for high-speed, low-voltage signal line protection against transient overvoltages. It is designed to offer maximum reliability and excellent surge eradication capability even in the most hostile environments. It has a low capacitance design with a working frequency of over 1 GHz and can handle up to 100V ESD pulse.
