8.3 Feature Description

The TVS2201 is a precision clamp that handles 30 A of IEC 61000-4-5 8/20 µs surge pulse. The flat clamping feature helps keep the clamping voltage very low to keep the downstream circuits from being stressed. The flat clamping feature can also help end-equipment designers save cost by opening up the possibility to use lower-cost, lower voltage tolerant downstream ICs. This device provides a bidirectional operating range, with a symmetrical V_RWM of ±22 V, designed for applications that have bipolar input signals or that must withstand reverse wiring conditions. The TVS2201 has minimal leakage at V_RWM, designed for applications where low leakage and power dissipation is a necessity. Built in IEC 61000-4-2 and IEC 61000-4-4 ratings make it a robust protection solution for ESD and EFT events and the TVS2201 wide ambient temperature range of –40°C to +125°C enables usage in harsh industrial environments.
