TVS - Diodes

TVS diodes are a type of specialised electronic component used to protect electronic circuits from damage by voltage transients, such as those generated by lightning strikes and electrostatic discharge (ESD). These transients are brief, high-voltage events that can exceed thousands of volts in amplitude, and are caused by changes in electrical current travelling through circuits. TVS diodes are designed to absorb the excess voltage, dissipating it in such a way that the electronic circuit remains undamaged.

1.5SMC68AHR7G Application Field and Working Principle

The 1.5SMC68AHR7G TVS diode is a single unidirectional Transient Voltage Suppressor (TVS) diode, designed for use in protection against transient HIGH energy surge. It has a positive breakdown characteristics, stands up to 8A of surge current, and a peak pulse power rating of 600W. It is ideal for protection against ESD (electrostatic discharge), surges, and overvoltage transients over a wide operating temperature range.

The working principle of the 1.5SMC68AHR7G TVS diode is as follows. In normal operation, when the voltage applied to the TVS diode is below the diode’s breakdown voltage, it behaves like an open circuit and does not conduct any current. When the applied voltage exceeds the breakdown voltage, the diode starts conducting, and the excess voltage is directed to ground, protecting the circuit from damage. The voltage across the diode rises and falls, depending on the amount of current passing through it. The diode continues to conduct until the current and voltage drop to safe levels.

The main applications for the 1.5SMC68AHR7G TVS diode are in the fields of telecommunications, data storage, industrial automation, power tools and medical equipment. It is generally used to protect sensitive components from electrical transients, surges, and ESD, which can cause damage to integrated circuits.

The 1.5SMC68AHR7G TVS diode is an excellent choice for protecting sensitive electronic systems from transient overvoltage events. Its high peak surge current rating and wide operating temperature range make it suitable for a wide range of applications.
