Transient Voltage Suppressors (TVS) are electronic components that can be used for protecting electronic circuits from excessive voltage transients. The SMBJ7.0D-M3/I is a surface mount TVS diode designed to protect specific voltage sensitive components from transients. The primary application of this diode is to protect a printed circuit board from surges that can result from lightning, power cross, or other high-voltage sources.

The SMBJ7.0D-M3/I is a bi-directional TVS diode with an interference voltage of 7.0 Volts and an IEC rating of 10000 V/m. Its maximum peak pulse power dissipation is 750W. The operating temperature range of this device is -55℃ to +175℃. It is a unidirectional device, which means it can only protect a circuit when a surge flows in one direction and does nothing to protect if the surge flows in the opposite direction.

The working principle of the SMBJ7.0D-M3/I is to reduce the voltage of the surge to a level which is safe for the components in the circuit. When the voltage level of the surge exceeds the breakdown voltage of the diode, it enters the avalanche breakdown region. Once it enters the breakdown region, the current in the device begins to increase exponentially. This exponential increase of the current results in a rapid reduction of the voltage. As the surge passes, the diode is restored to its normal state.

The SMBJ7.0D-M3/I is ideal for use in a wide range of applications, including power supplies, telecom/network cabinets, automotive systems and industrial and medical equipment. It can be used in most environments as it is resistant to moisture, dust and corrosive gases and is UL rated. It is also available in a variety of package sizes to meet various design requirements.

In summary, the SMBJ7.0D-M3/I is a surface mount TVS diode designed to protect specific voltage sensitive components from transients. It has a range of features and benefits, making it ideal for use in a wide range of applications. The diode operates by reducing the voltage of the surge to a level which is safe for components within the circuit, and is capable of handling high peak surge currents without damage. Lastly, it is available in a variety of package sizes to meet different design requirements.
