TVS (Transient Voltage Suppressor) diodes are specialized transistors designed to protect other electronic components like microprocessors and serial ports from destructive voltage spikes. The SMBJ75ATR is a unidirectional TVS diode that is particularly suited to protect against high-energy transients and electrostatic discharge (ESD). This article will cover the application field of the SMBJ75ATR and its working principle.

The SMBJ75ATR is a unidirectional, bi-directional protective diode. It is designed for ESD protection in the range of 30V to 75V, and is able to withstand a maximum surge current of 10A. This makes the SMBJ75ATR suitable for a wide range of applications, including computers, communication systems, measurement instruments, consumer electronics, automotive electronics, and industrial control devices.

The working principle of the SMBJ75ATR is based on avalanche multiplication in a PN junction. When there is a high-energy surge through the diode, the electric field across the junction becomes sufficiently large to break down the junction barrier, causing an avalanche of electrons and holes. This avalanche current propagates through the junction and is dissipated as heat, thus preventing the surge from reaching the electronic components behind it.

The SMBJ75ATR is able to withstand a high surge current due to its low on-state resistance. This low resistance allows the transient protection diode to reduce the voltage drop across the diode to less than 1V, hence reducing power dissipation that can occur in other TVS diodes. Additionally, the SMBJ75ATR has a low clamping voltage of 28V, making it ideal for protecting components from transient voltages.

In conclusion, the SMBJ75ATR is a unidirectional TVS diode that is well-suited for various applications requiring ESD protection. It is able to withstand a high surge current due to its low on-state resistance, and has a low clamping voltage that effectively prevents transient voltages from reaching the electronic components behind it. Its performance, coupled with its low cost, makes the SMBJ75ATR an ideal choice for protecting vulnerable electronics from spikes and surges.
