The TVS2200 robustly shunts up to 40 A of IEC 61000-4-5 fault current to protect systems from high power transients or lightning strikes. The device offers a solution to the common industrial signal line EMC requirement to survive up to ±1 kV IEC 61000-4-5 open circuit voltage coupled through a 42 Ω impedance.
The TVS2200 uses a unique feedback mechanism for precise flat clamping during a fault, allowing system exposure below 30 V. The tight voltage regulation allows designers to confidently select system components with a lower voltage tolerance, lowering system costs and complexity without sacrificing robustness.
In addition, the TVS2200 is available in a small 2 mm × 2 mm SON footprint which is designed for space constrained applications, offering a 70 percent reduction in size compared to industry standard SMA and SMB packages. The extremely low device leakage and capacitance causes a minimal effect on the protected line. For robust protection over the lifetime of the product, TI tests the TVS2200 against 5,000 repetitive surge strikes at high temperature with no shift in device performance.
The TVS2200 is part of TI’s Flat-Clamp family of surge devices. For more information on the other devices in the family, see the Device Comparison Table.

FLAT-CLAMP-TVS-EVM — TVSxx0x 精密突波防護二極體評估模組
TIDA-010008 — 適合電網應用瞬態保護的平箝制 TVS 架構參考設計
TIDA-050047 — 整合式 USB Type-C®、USB 電力輸送和 2-4 芯電池的充電參考設計
此參考設計可在 5 A 電流下充電至 20 V，無需任何外部 FET，進而大幅縮小解決方案尺寸，並降低總 BOM 成本。此外也不需要微處理器，因為 TPS25750 電力輸送 (PD) 控制器會處理與 BQ25798 電池充電器 IC 的 I2C 通訊。此 I2C 功能與 TPS25750 Web 架構 GUI 可大幅簡化韌體開發程序。
