The VG121030H620DP is an application-specific, two-terminal device typically used in varistors. It features a high surge energy rating, low capacitance and low clamping voltage. The device is designed to provide protection from surges caused by lightning, power lines, UPS systems and other sources.

The VG121030H620DP is a Metallized Polypropylene AC Voltage Varistor, designed for high energy surge protection applications. It is designed for AC line protection of lighting, industrial control systems, medical equipment and other systems where transient voltage surges may occur.

A varistor is a two-terminal semiconductor device, typically composed of a ceramic material such as zinc oxide, which exhibits a measurable non-linearity in its I-V curve. In normal operation a varistor appears as a pure resistance, allowing a constant current to pass through it. However, when exposed to a voltage surge, the varistor will enter into breakdown, providing a low impedance path to dissipate the energy of the transient.

The VG121030H620DP is designed to provide unsurpassed protection from surges with an extremely low clamping voltage. The device has a built-in thermal protection feature that ensures reliable operation at high ambient temperatures. The device is designed to quickly dissipate transients that exceed the specified breakdown voltage.

The VG121030H620DP also features an extremely low capacitance, which ensures a low frequency response and minimized interference with sensitive signals. The built-in self-healing properties of the device ensure long-term reliability under the most extreme circumstances. The device is optimized for superior surge protection against both ESD and electrical fast transients (EFT).

The VG121030H620DP is a highly reliable solution for protecting sensitive electronic circuits from voltage transients. This device offers outstanding surge protection, with a high surge energy rating, low capacitance and low clamping voltage. The device is designed for AC line protection of lighting, industrial control systems, medical equipment and other systems where transient voltage surges may occur.
