SMDJ12C

SMDJ12C application field and working principle

Surge protection devices (SPDs) are the most commonly used devices for over-voltage protection. They are widely used in electronic circuits, telecom systems, computer systems, data centers, personal computers and many other industries. The SPD is a diode installed in parallel on the line and connected to the ground, commonly used is the SMDJ12C. This application field of SMDJ12C and its working principle is discussed in this paper.

Application Field of SMDJ12C

SMDJ12C is a type of surge protection devices and it can be used to protect electronic circuits, telecom systems, computer systems, data centers and personal computers. It is especially suitable for protecting such equipments from over voltage surges and lightning strikes. SMDJ12C surge protector can prevent power supply from losing power in the event of overvoltage or surge, which will cause the system to power failure. It is the most essential component of protective systems.

Working Principle of SMDJ12C

The working principle of SMDJ12C is simple. Its function is similar to that of a diode. The SMDJ12C is connected to the power supply line in parallel to the load, or between the load and ground. When the AC surge is greater than the breakdown voltage, the SMDJ12C will be turned on and the surge current will be diverted from the circuit which can protect the circuit from being destroyed. It can also protect the machine from overvoltage damage, and the overvoltage current from leaking into the ground to prevent accidents.

Conclusion

The SMDJ12C is widely used in electronic circuits, telecom systems, computer systems, data centers and personal computers where protection from over-voltages, surges and lightning strikes is needed. It works similar to a diode and can protect the system from power failure in the event of overvoltage. With its protective capabilities, SMDJ12C is an essential component of any protective system.
