TVS - Diodes are widely used in the field of electronic components. The SMBJ22CA R5G is a typical type of the TVS - Diode. It is an ultra-fast, bidirectional, low capacitance, unidirectional and transient voltage suppressor diode which is designed to protect sensitive low voltages equipments from voltage transients induced by lightning or other hazardous conditions.

The SMBJ22CA R5G consists of two ultra-fast, bidirectional, low capacitance, unidirectional and transient voltage suppressor diodes, connected to opposing terminals and stored in a single package. The overall structure of the diode is quite simple and includes two cathodes, an anode for one diode and a cathode for the other.

The application fields of the SMBJ22CA R5G include high frequency protection circuits, mobile communication equipments, base station protection circuits and so on, which are all of the low voltage protection field. In addition, this type of diode can also support a wide range of voltages, typically from 6 volts up to 8000 volts. This means that it can be used in wide range of activities such as USB interfaces, digital ICs, data & communications circuit protection, automotive electronics, RF and ESD protection, and so on.

In terms of working principle, the SMBJ22CA R5G diode works in a way that if the voltage increase in any direction is beyond the maximum rating, the diode will break down momentarily, allowing current to flow in and out of the device very quickly. As the input voltage is clamping, the diode then acts as a resistor, limiting the excess current. Over time, the current is balanced, allowing the voltage to the device to slowly recover back to nominal levels. In such way, it provides robust protection to the device, from voltage transients.

In conclusion, SMBJ22CA R5G is a type of TVS - Diode that is widely used in the field of electronic components due to its wide range of applications, relatively simple structure and effective working principle. It is an ideal choice for the low voltage protection circuit, effectively protecting the connected device from voltage transients.
