TVS diodes, also known as Transient Voltage Suppressors (TVSs), are silicon-based components that protect electrical circuits from voltage transients produced by lightning, electrostatic discharge, and/or induced by other forms of current-based disturbances. The most widely used type of TVS diodes are the SMBJ75CA-M3/5B. These diodes are specially made for the purpose of safely and effectively protecting circuits from disruptive surges of electricity that can cause significant damage if left unchecked.

The SMBJ75CA-M3/5B is a type of fast-acting surge protection diode that is designed to protect sensitive electronic components by suppressing the short-term transient voltages associated with a surge or spike. This diode has a maximum peak pulse power dissipation of 1500-Watts at 10/1000 microsecond waveform and a maximum pulse current of 17.8A at 8/20 microsecond waveform. It has an unclamped voltage of 5.8V, which means it is capable of protecting sensitive components from up to 5.8V of transient overvoltage.

The SMBJ75CA-M3/5B’s application field is mainly used for circuit protection when applicable overvoltage needs to be kept below 5.8V. It is often used in power supplies and surge suppression circuits, as well as on the inputs and outputs of microprocessors, logic components, and digital logic systems. Furthermore, due to its high surge current rating, this diode is frequently employed as a shunt regulator for capacitive discharge applications.

In terms of its working principle, the SMBJ75CA-M3/5B is designed to conduct a surge current (in the form of a voltage spike) away from the sensitive circuit’s components. This is accomplished by clamping the input voltage to the surge voltage, thus safely and effectively limiting the system\'s direct exposure to the dangerous overvoltage. In addition, this diode’s peak pulse power surpasses most other diodes, meaning it can handle higher surge currents without any issues.

The SMBJ75CA-M3/5B is an effective TVS diode for providing surge protection in a variety of applications. Its robust design and high surge current rating make it suitable for protecting sensitive components from overvoltage while also allowing the relevant circuit to remain operational. Due to these features, the SMBJ75CA-M3/5B is one of the most popular diodes employed for applications requiring transient voltage suppression.
