Transient Voltage Suppression (TVS) devices are critical components that protect sensitive and valuable electronic equipment like cell phones, consumer electronics, and even medical and military systems from power surges, electrostatic discharges, and other electrical transient events. The Varistors, Metal Oxide Varistors (MOVs), and Thyristor Surge Protection Devices (TSPDs) are all types of TVS devices that provide series or parallel protection for sensitive equipment. The VDRS07H275BKE is a single component that combines four MOVs with four bidirectional Thyristor Surge Protection Devices (TSPDs) making it an ideal choice for a wide range of end applications.

The VDRS07H275BKE is a surface mount device is designed to offer efficient absorption of transient voltage events and is best suited for portable devices or applications where space is critical. This device is highly effective in providing protection against transient voltage events, making it ideal for applications such as consumer electronic equipment, computers, office equipment, medical and military systems, mobile phones, and automotive electronics. Its low profile design makes it well suited for applications where limited space is available. The total protection area of the VDRS07H275BKE is up to 15mm2.

The VDRS07H275BKE device consists of a combination of four spark-gap TVS diodes and four bidirectional TSPDs which are connected in parallel. The two components of each pair are connected to form a series configuration. This ensures that both components are activated when a surge strikes, providing a higher level of protection than when only one component is used. The device is designed to protect against transient voltage events, which can cause costly damage to a system if not detected and countered in time.

The VDRS07H275BKE device is capable of handling an energy discharge of up to 55A (with a maximum peak of 2.8kV) and a response time of less than 20ns. It is rated for a maximum operating voltage of 4.2V and a maximum surge current of 55A (with a response time of 0.2μs). The device has a low capacitance (3pF), which helps to reduce electromagnetic interference.

The working principle of the VDRS07H275BKE is based on its Varistor MOV and TSPDs, which are connected in series. During normal operation, the device is non-conductive, which means that there are no electrical connections between the two components. However, when an overvoltage or transient voltage event occurs, the two components become conductive and provide conductive paths to return the energy back to ground. This has the effect of redirecting, absorbing, and quickly dissipating the surge energy, thus preventing it from causing damage to sensitive electronic components.

In summary, the VDRS07H275BKE is an advanced surge protection solution that is suitable for a wide range of end applications. It is designed to provide efficient absorption of transient voltage events and is highly effective in providing protection against damaging surges. Moreover, its low profile design and high performance characteristics make it an ideal choice for space-constrained applications. It is an essential component for any system requiring effective surge protection from damaging transient events.
