TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are common types of electric components used to protect electrical systems from transients. The VDRS07H275TGE is a 350VAC, 275V RMS, Bidirectional Bidirectional TVS Device. It is designed to provide circuit protection against voltage transients, electrostatic discharges and other over-voltage stress conditions.

The VDRS07H275TGE is typically used in applications such as HVAC systems, medical equipment, industrial controls, automotive components, communications equipment, and consumer electronics. Its low profile and compact design makes it suitable for use in applications that require high component density.

When exposed to a voltage transient, the VDRS07H275TGE works by diverting the surge current from the sensitive circuitry and preventing any permanent damage from occurring. It is able to do this by creating a low impedance path for the surge current to flow through, while at the same time clamping the voltage to a safe level.

The VDRS07H275TGE uses an avalanche voltage breakdown when it is stressed beyond its rated clamping voltage. This process involves a large amount of current being driven through the device, and the breakdown voltage is determined by the breakdown characteristics of either silicon or zinc oxide material used as the MOV material.

The electric field within the device is strong enough to ionize the air and cause a conductive path to form, which allows the surge current to flow to ground. When the excess current has been diverted, the device returns to its normal operating condition.

The VDRS07H275TGE also has a highly durable catalyst layer that absorbs the thermal energy generated by the voltage and current surges. This prevents the possibility of catastrophic failure of the device under high-energy conditions, and in turn adds extra protection to the sensitive components connected in series to it.

Due to its bidirectional design, the VDRS07H275TGE can provide protection against current disturbances from both positive and negative voltage transients. This feature further increases its effectiveness for protecting a wide range of equipment and components.

The VDRS07H275TGE is suitable for a range of applications, including medical and industrial equipment, automotive systems, communications equipment, consumer electronics, and HVAC control systems. Its combined clamping action and thermal heat dissipation ensures reliable protection against transient overloads.
