TVS - Diodes are devices such as Transient Voltage Suppressor (TVS) Diodes that protect sensitive electronics from power surges, electrical transients, and electrostatic discharge (ESD). These devices, also known as spark-gap diodes, are specially designed to protect against transient events that may cause catastrophic failure of the components they are protecting. The SMLJ20A-Q is one such device, and is widely used in the protection of electronic systems.

The SMLJ20A-Q is a 20A, 600W TVS diode designed to protect low voltage, low power applications such as consumer electronics and military aerospace applications. It features a maximum peak pulse power rating of 6000 watts and a stand-off voltage of 20V. It is designed to provide reliable ESD and surge protection up to 20A in current surges of up to 600W. It is also capable of providing protection against repetitive pulses up to 80A in duration.

The working principle of SMLJ20A-Q is based on the PN junction diode structure. When the device is exposed to any type of voltage transient, it undergoes avalanche breakdown and begins to conduct current. This breakdown results in a rapid increase in voltage across the reverse current junction of the diode, which then redirects the transient to ground. This process prevents the transient from reaching the device or component being protected.

The SMLJ20A-Q also comes with other features that make it a great choice for TVS protection. It has an ultra-low capacitance of only 0.9pF which allows it to be used in high-speed data applications, and it also features a low breakdown voltage of 20V which ensures maximum protection for sensitive components. Additionally, it is rated to handle up to 8kV ESD and rated for a pulse width of 8/20 μs which are ideal conditions for the protection of sensitive components from power surges.

In summary, the SMLJ20A-Q is a rugged, reliable, and low-cost TVS diode that provides effective ESD, surge, and transient protection for low voltage, low power applications. Its low capacitance allows for use in high speed data applications, and its low voltage breakdown ensures that it will protect against transient events up to 20A in current. It is rated to handle up to 8kV ESD and up to 8/20 μs pulse width, making it ideal for the protection of sensitive components from power surges and electrostatic discharge.
