TVS (transient voltage suppressor) diodes are a type of power-threshold devices that are designed to protect voltage-sensitive components from voltage spikes. The SMA5J20C-E3/5A is a bidirectional TVS diode designed to provide protection from destructive voltage transients in a wide array of applications.

The SMA5J20C-E3/5A has a wide operating temperature range from -65 ˚C to 150 ˚C and is able to withstand transient surge voltages from 17 to 28 volts. In addition, this diode has an IEC 61000-4-5 surge immunity of 1500W (8/20μs) and an industry-leading peak pulse power rating of 4.0KW.

The SMA5J20C-E3/5A is primarily used in automotive, industrial, and consumer electronics applications. It can be used to protect voltage-sensitive components such as microprocessors, memory, and power supplies from excess transients. In automotive applications, the SMA5J20C-E3/5A can also be used to protect against transients caused by harsh environmental conditions such as ESD, EMC, and switching noises.

The working principle of the SMA5J20C-E3/5A is based on the technology of diode breakdown. When the voltage across the diode exceeds the breakdown voltage, the diode becomes conductive, allowing the transient current to be safely dissipated. This protects all of the components downstream of the diode from the destructive effects of the transient.

The SMA5J20C-E3/5A is a reliable and cost-effective solution for providing protection against destructive transient voltage transients. It is easy to install, requires minimal maintenance, and can be used in a wide variety of applications. In addition, the SMA5J20C-E3/5A has a low forward voltage drop and can withstand a wide range of transient peak pulse powers. This makes it an ideal solution for protecting sensitive electronics and components.
