TND12G-680KB0LAAA0

TVS - Varistors, MOVs are common forms of surge protection devices that are used to ensure the safety of electrical components and systems from power surges. The TND12G-680KB0LAAA0 is a popular TVS - Varistor, MOV, which is often used in power conditioning circuits. This article will discuss the application field and working principles of the TND12G-680KB0LAAA0.

Applications of TND12G-680KB0LAAA0

The TND12G-680KB0LAAA0 is typically used in power conditioning circuits, such as DIN rail surge protector, UPS, single phase and three phase AC power, power supply, PLC input/output diodes, etc. It is also used in automotive, industrial, telecom, aerospace, wireless and other applications. The device is designed to provide up to 20kA 8/20µs discharge current protection against transients, both ESD and EFT. The device also offers very fast response times of less than 1ns, excellent clamping characteristics, and very low capacitance and leakage current.

Working Principles of TND12G-680KB0LAAA0

The TND12G-680KB0LAAA0 is a metal oxide varistor (MOV) which works by clamping the voltage across the device to a safe level. It consists of a ceramic and metal oxide material with two layers of electrodes, one on either side. When a power surge occurs, the MOV acts as a voltage-dependent resistor and is able to limit the over-voltage condition and divert the surge energy away from the sensitive components. The MOV also acts like a capacitor, which is able to store the surge energy and release it gradually. This prevents any damage to the electrical components and helps them maintain their correct working parameters. The device is designed to be very durable, with low leakage current and excellent temperature stability.

Conclusion

The TND12G-680KB0LAAA0 is a reliable and durable surge protection device that is designed for use in power conditioning circuits. The device is used to protect sensitive components from transients, both ESD and EFT, by clamping the voltage and diverting the surge energy away. The device is also able to store the surge energy and release it gradually. It is tough, with low leakage current and excellent temperature stability. Thus, it is an ideal choice for ensuring the safety of electrical systems.
