TVS (Transient Voltage Suppressors) include three main categories, Varistors, MOVs (Metal Oxide Varistors), and TVS Diodes. The TVS Diode is a voltage-dependent, unidirectional semiconductor device which protects circuits from transients. The Varistor and MOV provide bidirectional protection and are not easily susceptible to ESD (Electro-Static Discharge) as well as RFI (Radio Frequency Interference). One of the leading devices in this category is VDR10D040BSE.

VDR10D040BSE is an 04-series non-linear Varistor specially designed for automotive and general electronics applications. It operates with a peak pulse power rating of 1000W and a rated working voltage of 40V. VDR10D040BSE also features a non-linearity degree of greater than 70%, a current rating of 4A, and an operating temperature range of -55 to +155°C.

The main application field of VDR10D040BSE is automotive and general electronics equipment. It is commonly used in fuel and heating systems, lighting systems, and airbags. Its primary function is to regulate voltage and current spikes associated with EMI (Electromagnetic Interference) and RFI in these applications. The device also helps to protect sensitive circuits from damaging transients.

The working principle of the VDR10D040BSE is based on a Zinc-Oxide (ZnO) Varistor technology. It is composed of a semiconductor layer made up of zinc oxide nanocrystals, which act as reverse-biased p and n regions. When a current spikes, the semiconductor switches on, allowing current to pass through the device. This current is redistributed across the device, allowing the voltage to decrease as the current passes through.

When the current spikes have dissipated, the semiconductor layer returns to its original off state. This is due to the resistance of the nanocrystals, as well as the internal capacitance of the device. The VDR10D040BSE is designed to provide reliable bidirectional protection against EMI/RFI signals, and it has a low leakage current, making it ideal for automotive and general electronics applications.
