TVS diodes are a type of transient-voltage-suppression diode. They are used in both military and civilian applications to protect delicate electronics from voltage surges such as those caused by lightning, electrostatic discharge (ESD), and other types of transient voltage. The SM6T68A-E3/5B is a type of TVS diode, and it is widely used in a variety of applications.

The SM6T68A-E3/5B Application Field

The SM6T68A-E3/5B is an ideal choice for the protection of sensitive electronic systems and components against overvoltage transients. It can be used in a number of applications, such as telecommunications, power supplies, automotive, and industrial equipment. The SM6T68A-E3/5B is designed for clamping down voltage surges that are within the diode’s breakdown voltage ratings. It can handle high-energy pulses up to 5kV (50Ω) with a maximum peak pulse power rated higher than 550W. This diode is contained in a small SMT package and provides excellent thermal stability, making it ideal for high-reliability applications.

Working Principle of The SM6T68A-E3/5B

The SM6T68A- E3/5B functions by acting as a clamping device that limits the voltage applied to a circuit. When a voltage surge enters the circuit, the SM6T68A-E3/5B kicks in and diverts the extra energy to a safe path, allowing the circuit to remain operational and protected from damage.The diode works according to the avalanche breakdown principle. When a high voltage is applied across the diode, the electric field within the diode is increased. When this electric field reaches a critical level, it initiates an avalanche breakdown of the diode\'s P-N junction, causing the voltage across the diode to increase rapidly. The rapid increase in voltage causes the diode to start conducting current, and the extra energy is diverted to a safe path.
