TVS - Varistors, MOVs is a generic name for a broad category of surge-suppressing semiconductor devices which contain nonlinear elements. VDRs14G017BSE is one type of such devices. This particular product is a bidirectional and rail-to-rail type voltage-dependent resistor (VDR) featuring a dual bidirectional TVS diode array.

The application field of VDRs14G017BSE is widely varied. It can be used for various surge protection applications, such as in telecommunications, networking equipment, automotive, consumer electronics, and medical equipment. This product is suitable for applications that require bidirectional transient protection. It provides protection from electrostatic discharge (ESD) and transient surges from both directions. Additionally, it provides rail-to-rail capability.

In terms of working principle, VDRs14G017BSE utilizes a negative temperature coefficient resistor (NTCR) element. This element produces a voltage-dependent resistance characterized by a decrease in resistance with increasing voltage. When a surge is applied, the resistance of the NTCR element decreases, allowing the current to flow through the VDR. At the same time, a diode array composed of multiple pairs of rectifying diodes becomes forward bi-directional to protect the device from further surges. Additionally, the internal resistance of the device contributes to the surge protection. The overall result of this mechanism is an effective surge protection system that can handle a wide range of voltage levels.

To summarize, VDRs14G017BSE is a bidirectional and rail-to-rail type surge protection device that is suitable for a wide range of applications. Its working principle relies on the combination of an NTCR element and a diode array to provide effective protection against both ESD and transient surges. It is an efficient and reliable surge protection system for various applications.
