VDRH07K320BSE

TVS - Varistors, MOVs are used for protecting sensitive electronic equipment from voltage transients, which are also known as surge protection devices. The VDRH07K320BSE is a common Varistor device manufactured by Semtech for industrial and consumer applications. It is designed to protect against a wide range of voltages and has a high peak pulse current rating.

Application Field

The VDRH07K320BSE is a two-terminal, 400V, zero-power, radial leaded device with a working voltage up to 800V. This device is mainly used in consumer electronic equipment, home appliances, audio systems, personal computer peripherals, USB ports, digital cameras, and other multimedia products. It is designed to dampen high-voltage spikes to reduce the risk of damage to sensitive devices.

Working Principle

The VDRH07K320BSE is based on the varistor principle. A varistor is a resistor that works on a semiconductor material and its resistance varies based on the applied voltage. When the applied voltage exceeds the varistor\'s rated working voltage, it automatically conducts, thus providing a low impedance path for the current. This protects against overvoltages, electrical transients, and excessive current spikes. When the voltage drops back below the rated working voltage, the varistor returns to its natural high-resistance state, thus removing the protection.

The VDRH07K320BSE has a peak current rating of up to 300A and can absorb up to 2000J of energy. It also has a high temperature prowess of up to 150°C, which gives improved durability. The device is a through hole component and it is rated for a high voltage surge up to 8000V. It is designed to protect against high-power transients such as lightning surges and power line transients.

The VDRH07K320BSE is UL recognized and approved according to CSA Standards. It is RoHS compliant and it is available in tape and reel packing for easy automated assembly and loading.
