The TVS-Diodes are mainly used in the protection of electronic devices and systems from voltage transients like electrostatic discharges, arcs, and indirect lightning strikes. In this regard, 4.0SMDJ24A is a robust dimension multi-strike transient voltage suppressor (TVS) from a wide range of Diodes Family. This product is used to protect the cables and many semiconductor based equipment, from disturbances that are typically found in the areas of lightning-prone and high-frequency environments. It can operate in a voltage range from 5 to 24 volts, and is available at an affordable cost.

The 4.0SMDJ24A application field and working principle is quite simple. Its bi-directional operation works across a wide range of voltages and current ratings. In the normal condition, the body diode is not active and no current can flow through the TVS diode. When overvoltage occurs, the TVS diode gets activated due to its high current capability and low forward voltage drop. The TVS diode maintains the voltage at a safe level by quickly clamping down the transient voltage level, thus providing complete protection from static electricity and sudden surges.

The 4.0SMDJ24A application field and working principle is divided into two types - unidirectional avalanche breakdown and bidirectional avalanche breakdown diodes. The unidirectional avalanche breakdown diode can be used in low-voltage applications, such as cellular phones, computers and other low-voltage loads. This type of TVS protects the circuit against positive and negative transients. On the other hand, the bidirectional avalanche breakdown diode works well in higher voltages, such as power supply applications, and helps protect against both positive and negative transients. Both of these types of TVS diodes are designed with a unique feature – a “quasi-triangle” diode service level.

The 4.0SMDJ24A application field and working principle also includes the use of \'\'Zener diodes\'\'. These diodes are used to protect against transient voltages that are higher than the normal operating level. A zener diode is connected in forward bias with respect to the voltage source. When the source voltage exceeds the breakdown voltage of the diode, the diode begins to conduct and clamps the voltage at the breakdown voltage. However, zener diodes offer limited protection and can be used only in low voltage applications.

In conclusion, the 4.0SMDJ24A application field and working principle is mainly used in protecting the circuits, along with a wide range of other TVS diodes. These diodes are designed to protect against static electricity and sudden surges. They are also used to protect against both positive and negative transients, depending on their application field. They have a wide range of voltages and current ratings, making them cost-effective and efficient in their operation. Both unidirectional and bidirectional types are available, depending on the applications. In addition, Zener diodes are also used in low-voltage applications for a certain degree of protection. Finally, all these devices are available at fairly affordable prices, and they can be easily integrated in the circuit.
