VDRS05C275BSE

TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are devices used to protect against electrical transients in power systems, specifically to guard against short-term voltage spikes. The VDRS05C275BSE is a TVS device designed to limit overvoltages induced by lightning, ESD (electrostatic discharge), and other electrical phenomena. This article will discuss the application field and working principle of the VDRS05C275BSE.

The VDRS05C275BSE utilizes a voltage-dependent silicon avalanche diode that acts as a shunt. This diode functions in a reverse state, allowing only a certain current through the device for a given voltage level. The voltage across the diode increases at a non-linear rate, as the current flow increases via avalanche breakdown. Typically, the voltage is limited to between 7V and 13V when the device\'s maximum rated voltage is reached. This current-limiting action helps protect components and devices downstream of it against voltage transients.

The VDRS05C275BSE is primarily used in high-power applications. Examples include power transmission lines, industrial controllers, power supplies, telecommunications, and consumer electronic equipment. When used in telecommunications applications, it is used to protect signal lines from transient voltage surges or accidental short circuits that might otherwise cause severe damage. In power supplies, it is employed to maintain a steady voltage across the load, as well as protecting from power line transients.

The VDRS05C275BSE is a unidirectional device, meaning it will only protect against voltage in the direction that it is installed. It acts by shunting high-voltage spikes away from the equipment being protected, thus limiting the voltage on equipment and protecting it from damage. The device is designed to handle a wide range of voltages, including transients ranging from 8V to 18V. It has a peak pulse rating of 75A and can survive up to 100V of surge voltage.

The device is rated for 10,000 cycles or more, which means it should not require frequent replacement or maintenance. The device can also withstand temperatures ranging from -55°C to +125°C. It is halogen-free and RoHS compliant and is available in lead-free and tin-lead finishes.

The VDRS05C275BSE is a high-quality, reliable device that can be used in a wide range of power applications. It provides excellent protection against voltage transients, including lightning strikes, ESD, and other electrical phenomena. It is an easy-to-use device with a long lifespan and is compliant with a number of international standards. It is a cost-effective way to ensure the protection of equipment and components from dangerous voltage transients.
