TVS (transient voltage suppressor) devices, MOVs (metal oxide varistors) and V07E300s (voltage-dependent resistors) are components used to protect circuits and human users from static and transient voltage events. TVS-type devices reduce overvoltage from high voltage transients, MOVs are high voltage surge protectors, and V07E300s are ESD (electrostatic discharge) protection devices which divert large surges or electrostatic discharges to ground.

The V07E300 is a specially designed, bidirectional voltage-dependent resistor (VDR) based on an array of low-resistivity varistors. It is designed to protect systems from electrostatic discharge (ESD) or transient events. It offers ESD protection of Human Body Model (HBM) above 95V or Machine Model (MM) above 95V for a standard 50mA pulse, as well as ESD protection of HBM above 300V or MM above 230V for a standard 30A pulse. It also offers lightning and surge protection that meets IEC 61000-4-5 Grade 4 (8/20 microsecond) levels.

The V07E300 also features low clamping voltage, low leakage current, low insertion loss and high peak current capacity. Its low-resistance construction supports high peak current capability, allowing it to withstand multiple high-energy pulses. The internal design features an array of low-resistivity zinc-oxide varistors combined with a special design typical of VDRs. This design provides superior protection with low parasitic elements, which result in better EMC performance.

The working principle of the V07E300 is based on its voltage-dependent design, which allows it to reduce physical movement of electrons from one point to another. When a voltage is applied, the varistor components within the V07E300 respond by increasing their resistance until the voltage reaches a certain value, at which point the varistors begin to reduce their resistance. This process of increasing and decreasing resistance provides ESD and transient voltage protection. As the voltage rises, the varistors reduce their resistance, allowing the current to be diverted to ground, rather than allowing it to pass into the protected circuit.

The V07E300 is often used in consumer and industrial applications, such as cell phones, telephone systems, computers, and automotive electronics. It is also often used to protect against interference from EMI (electromagnetic interference) sources. It can also be used in various power systems, such as transformers, UPS systems, inverters, and solar energy systems. Additionally, the V07E300 can be used to protect against reverse-polarity or voltage transients.

The V07E300 is a cost-effective, highly efficient solution for providing transient and overvoltage protection. Its unique voltage-dependent design offers superior protection from transient and ESD surges, and its low parasitic elements provide better EMC performance. Additionally, its low clamping voltage, low leakage current and high peak current capacity make it ideal for a variety of applications.
