Transient Voltage Suppressors (TVS) and Metal Oxide Varistors (MOVs) have become increasingly important protection devices in the modern world of electronics. The VC120618D400DP transient voltage suppressor is an excellent example of how these devices can be used to safeguard electronic components and circuits from destructive transient voltages. This article will explain the application field and working principle of this important transient voltage suppressor.

The VC120618D400DP transient voltage suppressor is designed for transient voltage protection and ESD immunity of sensitive electronic components and circuits. The device has a reverse stand off voltage of 18V and a maximum peak pulse current more than 400A. This means that it is suitable for the protection of a wide variety of circuits operating at anything up to 18V, including low-voltage logic circuits, power supplies, and telecommunications equipment.

The working principle of the VC120618D400DP is relatively simple. When the voltage across the device exceeds its reverse stand off voltage, a passing current will be conducted through the device. This current is clamped off if it exceeds its maximum peak pulse current, thereby protecting the circuit from further damage. This means that the device can protect against power surges, ESD events, and other damaging transient voltages.

The VC120618D400DP transient voltage suppressor offers several advantages over other protection devices, such as insulated gate bipolar transistors and zener diodes. Its flat response curve means that it can effectively clamp off reverse stand off voltages without distorting the waveform of the power supply. In addition, its low capacitance design ensures that it can be used in high-speed communication circuits. Finally, its low profile design ensures that it is suitable for installation in tight spaces, making it ideal for use in portable electronics.

In summary, the VC120618D400DP transient voltage suppressor is an ideal choice for the protection of sensitive electronic components and circuits against high voltage transients. Its flat response curve, low capacitance design, and low profile make it an ideal choice for a wide range of applications. Its reverse stand off voltage and maximum peak pulse current are suitable for the protection of circuits operating at anything up to 18V, making it an excellent choice for low-voltage logic circuits, power supplies, and telecommunications equipment.
