TVS (Transient Voltage Suppressor) diodes are used to protect against harmful electrical transients, or surges, in high-voltage electric systems such as those found in industrial facilities, consumer electronics, and automotive applications. This article will discuss the application field and working principle of the LC130, a type of TVS diode that is often used in these applications.

The LC130 is a general-purpose three-terminal, unidirectional, transient voltage suppression diode. It is designed to protect sensitive electronic components, ICs, and other circuits against voltage and current transients in AC or DC power supplies, as well as in communication lines. The diode has a nonlinear reverse-recovery characteristic, which allows it to absorb or dissipate large amounts of power over a wide range of voltages without damage.

The LC130 can be used in a variety of applications, including industrial electronics, consumer electronics, automotive electronics, power supplies, motor drives, and other power conversion equipment. It is especially useful in applications where the peak voltage required to trigger the diode is higher than the normal operating voltage of the target circuit. This is due to the fact that the LC130 has a relatively high peak voltage rating – ranging from 200V to 400V – which makes it suitable for many high-voltage industrial and automotive applications.

The LC130 is an unidirectional TVS diode, meaning that it only resists voltage or current flowing in one direction. When the voltage or current exceeds the threshold level of the diode, the LC130 begins to conduct, clamping any further increase in voltage or current. As the exposed voltage or current decreases, the LC130 will gradually return to its off state.

The LC130 is also designed to have a series of positive temperature coefficient characteristics, which are essential for its protection against transients. Higher temperature increases the diode’s reverse recovery time. This prevents any possible damage to the target circuit, since transients dissipate quickly as the reverse recovery time increases. Conversely, lower temperatures can reduce the reverse recovery time of the diode, potentially causing it to become overloaded and damaged if large transients occur.

The LC130 has several advantages over other types of transient voltage suppression diodes. It is relatively easy to assemble, requiring only three terminals, and is cost-effective when compared to other TVS diodes. Additionally, its series of positive temperature coefficient characteristics helps to protect against any sudden, unintended, transient-induced overloads.

In conclusion, the LC130 is a widely used TVS diode, due to its relatively high peak voltage rating, ease of assembly, and cost-effectiveness. The diode’s unidirectional characteristics and positive temperature coefficient characteristics make it well-suited to a variety of applications where protection against transient voltage or current surges is needed.
