TVS2700DRVR

The TVS2700 can reliably divert IEC 61000-4-5 fault currents of up to 40A to protect the system from high-power transient shocks or lightning strikes. This device provides a solution to meet the common EMC requirements of industrial signal lines and can withstand an IEC 61000-4-5 open-circuit voltage of up to ±1kV when coupled through a 42Ω impedance. The TVS2700 uses a unique feedback mechanism to ensure precise and smooth clamping capability during faults, guaranteeing that the system contact voltage remains below 35V. Precise voltage regulation allows designers to confidently select system components with lower voltage tolerances, reducing system cost and complexity without compromising reliability.

In addition, the TVS2700 is also available in a small 2mm × 2mm SON package, suitable for space-constrained applications. Compared with the industry-standard SMA and SMB packages, the size is reduced by 70%. The extremely low device leakage current and capacitance ensure minimal impact on the protected lines. To ensure reliable protection throughout the product's lifespan, the TVS2700 has been tested with 5,000 repeated surge shocks in a high-temperature environment without any change in device performance.
