TVS (transient voltage suppressers) diodes are widely used in many electronic products as protection devices against transient high-voltage or fast-rising-voltage disturbances. 824014 is one type of these protection components. This article discusses the application field and working principle of 824014.

Application Field of 824014

824014 is mainly suitable for the circuit protection of electronic products and equipment exposure to surge impact current, overvoltage, reverse polarity and lightning strikes. Thanks to its compact structure, 824014 is also applied in automotive electronics, GPS, communications equipment, wirelesse security systems, optical communications, automobile lighting, automobile electronics and computer (motherboard) protection.

Working Principle of 824014

824014 is a transient voltage suppressor diode with three-terminal structure. The main structure of 824014 is a small clamp varistor with three-terminal structure: anode, cathode and clamp terminal. When the input voltage increases to a certain value, the junction at the clamp terminal will be broken immediately. This process is called "clamping" and the junction is called a "breakdown contact". When the voltage is higher than the breakdown contact voltage, the 824014 will be connected in "series" with the current in the circuit. The so-called "series" means that the 824014 and the current in the circuit will form a loop, and the current passing through 824014 will be limited due to the resistance of 824014.

Conclusion

This article has discussed the application field and working principle of 824014. 824014 is widely used in electronic products for protection against transient high-voltage or fast-rising-voltage disturbances. It is a three-terminal device consisting of a small clamp varistor. When the input voltage reaches a certain value, the breakdown contact will be broken and 824014 will be connected in series with the current in the circuit. This will limit the current passing through it and thus protect the circuit.
