The V681HF34 is a TVS - Varistors, MOVs device. It is used to protect electronic circuits from high voltage spikes and surges. It is designed for use in low-voltage, high-frequency applications where it can withstand up to 4 kV peak voltage and 0.5 A surge current. The device is rated to withstand up to 8 kV transient voltage and 0.1 A 8x20 μs current.

The V681HF34 consists of two parts. The first is an aluminum oxide varistor, which is a metal-oxide semiconductor that changes its electrical properties when a voltage spike is applied to it. This change in electrical properties acts like a short-circuit, limiting the voltage across it. The second part is a spiral-wound ribbon of metal foil, which acts as a inductor for high frequency applications. The two parts are connected in series, allowing the device to handle both high-voltage and high-frequency applications.

When a transient voltage is applied to the V681HF34, the aluminum oxide varistor acts as a voltage-limiting device by reducing the voltage across it to a safe level. Then the metal foil inductor helps reduce the current through the device by cutting down on the high-frequency components of the transient voltage. This combination of protection devices results in a much more effective solution than either device alone.

The V681HF34 can be used in a wide variety of applications including switching power supplies, telecom equipment, consumer electronics, and automotive electronics. Its ability to handle high-voltage spikes and surges offers improved protection against voltage transients and power outages. Its ability to handle high-frequency transients makes it ideal for use in switching power supplies where high-frequency noise can cause problems.

The V681HF34 offers superior performance for protecting electronic circuits against transient voltage and surge current. Its two-part design helps to effectively reduce both high-voltage and high-frequency spikes. Its wide range of applications makes it a great choice for protecting electronic circuits in consumer and automotive electronics, telecommunications equipment, and switching power supplies.
