TVS - Diodes are electrical components used to protect equipment - such as computers, communication cables, and other sensitive electronic systems - from transient voltage changes. The SMA6J20A-E3/5A is a type of Transient Voltage Suppression (TVS) diode designed to protect sensitive electronic equipment from damage caused by electrical transients, often referred to as " induced surges ".

SMA6J20A-E3/5A is designed for low capacitance, very low leakage and high surge current handling capabilities (up to 3.6A peak pulse current). The device features a high holding current and excellent clamping capability, with its dielectric strength of 29kV, making it ideal for applications requiring a fast response time and high surge current handling capability. This makes the device suitable for a wide range of applications, such as automotive, industrial, medical, telecoms, consumer electronics, solar and wind turbines, and military and aerospace.

In terms of its working principle, the SMA6J20A-E3/5A is a semiconductor device which is designed to behave like a switch, with the primary purpose of protecting sensitive electronic circuits from damage caused by voltage spikes, such as transients. The diode consists of two semiconductor p-n junctions of opposite polarity connected in reverse parallel. When the circuit to which the diode is connected to is subjected to a transient voltage, the current flows through the diode and is diverted away from the circuit, thereby protecting it from the effects of the voltage spike.

The device also works as a voltage clamp, in which case the diode is connected in series with the circuit being protected. The diode acts as a voltage limiter by limiting the voltage across it to a predetermined voltage level. When the voltage across the diode exceeds its clamping voltage, the diode will conduct to divert the unwanted current away from the circuit, thereby providing a protective voltage clamp.

The SMA6J20A-E3/5A also offers excellent protection against high-frequency electrical transients. Its high-frequency noise suppression characteristics are the result of its low capacitance values, which are optimized for the best protection against electrical transients of frequencies higher than 5MHz. In addition, its maximum holding current of -3.2A helps protect the device from electric overloads and ESD damage.

In summary, the SMA6J20A-E3/5A is a type of TVS diode designed for use in many applications where protection from transient voltage is required. Its low capacitance and high surge current handling capabilities make it ideal for a wide range of applications ranging from automotive to consumer electronics. Its protective functioning is based on its ability to conduct current away from the protected circuit and/or limit the voltage across it. Finally, its high-frequency noise suppression capabilities also make it effective against electrical transients of high frequencies.
