TVS (Transient Voltage Suppressor) Varistors, MOVs (Metal-Oxide Varistors), and VDRS05C130ASE represent the epitome of overvoltage protection. Each type of device works differently to protect circuits from overvoltage damage while also providing some form of electrical isolation. In this article, we will look at VDRS05C130ASE and its use in the field as well as its working principle.

VDRS05C130ASE devices are transil diodes that provide general-purpose overvoltage protection. They are robust against voltage transients with a high peak pulse current capability of up to 5A. With a wide range of working voltages (3.3V to 30V), VDRS05C130ASE provides reliable protection against overvoltage from a variety of sources, be it from electrical hazards, lightning surges, or nearby strong electromagnetic interference.

The VDRS05C130ASE has a variety of applications in different fields. It is regularly used in consumer products to provide protection against excessive voltage, such as overvoltage protection in power supplies, data lines, and signal lines. In automotive industry, it can be used in hybrid vehicles to protect high-voltage power circuits and onboard computers from electrical and lightning surges. As an industrial-grade protector, its fast response time is suitable for surge protection in motor control circuits, building automation, lighting, and measurement systems.

The working principle of a VDRS05C130ASE is fundamentally based on the avalanche voltage breakdown in the PN junction diode. When the voltage across the diode exceeds its rated breakdown voltage, it enter a non-linear avalanche breakdown region, increasing its conductivity. This causes the PN junction to start conducting heavily and thus suppressing the overvoltage.

In addition, VDRS05C130ASE devices also provide electrostatic discharge (ESD) protection. During fast transients, the avalanche breakdown region ensures that any high voltage will be discharged quickly, limiting the potential damage to the circuit. This is further reinforced by the ESD protection, which acts as a buffer between the circuit and the outside world, preventing any high-energy ESD pulses from entering the circuit and damaging components.

To recap, VDRS05C130ASE is a type of TVS (Transient Voltage Suppressor) that provides superior overvoltage protection and ESD immunity. It is suitable for use in a range of applications such as consumer products, automotive, and industrial electronics. The device works by entering avalanche breakdown region when the voltage exceeds rated breakdown voltage, allowing it to suppress overvoltage quickly and effectively.
