TVS (Transient Voltage Suppressors) is a passive component used to protect against lightning, electrostatic discharge and other overvoltage transients. Varistors, or voltage-dependent resistors, and MOVs (metal oxide varistors) are two of the most commonly used types of transient voltage suppressors. VDRS07B030TGE is a Varistor product from Vishay, and this article will discuss its application field and working principle.

The VDRS07B030TGE is an unidirectional Varistor device, also known as a transient voltage surge suppressor (TVSS). It is designed for use in high-voltage protection applications such as overvoltage protection. It has an operating voltage of up to 30 VDC and a continuous unidirectional input voltage range of 7 VDC to 17 VDC. This makes it ideal for use in sensitive and critical applications such as automotive, industrial or telecom equipments.

The VDRS07B030TGE also features an ultra-compact package design, meaning it can be easily mounted in small and confined spaces. It is also ultra-rugged and highly reliable, with a long service life and a high peak current rating of up to 2.6 Amps. Additionally, it maintains a low on-state voltage with no residual voltage. This makes it suitable for use in applications where high peak current and low on-state voltage are paramount.

The VDRS07B030TGE Varistor works by redirecting a transient overvoltage by diverting the current away from sensitive components or circuits. This is accomplished by a non-linear resistive element within the Varistor which drastically changes its resistance when an overvoltage surge is detected. When a surge is detected, the Varistor’s non-linear resistive element will instantly change its resistance, providing an alternate path for the surge to be diverted away from the protected component or circuitry.

As Varistors are non-linear devices, their response is affected by both the peak voltage of the transient and the duration of the surge. As such, it is important to select a Varistor with a voltage rating that is equal to or higher than the peak voltage of the expected surge. It is also important to note that the Varistor’s peak current handling capacity should be adequate to handle the highest expected voltage and duration of the transient.

In summary, the VDRS07B030TGE is a Varistor device from Vishay that is designed for use in high-voltage protective applications such as overvoltage protection. It features an ultra-compact design, making it suitable for use in tight spaces or under intensive environmental conditions. It has a long service life and is highly reliable, with excellent peak current handling capabilities. Additionally, it can easily reroute a transient overvoltage, providing circuit protection by diverting the current away from sensitive components or circuits.
