Overview
The TVS2200DRVR from Texas Instruments is a 22V flat-clamp surge protection device designed to provide robust protection against high-power transients and lightning strikes. This device is part of TI's Flat-Clamp family of surge protection devices and is engineered to handle up to 40 A of IEC 61000-4-5 8/20 µs surge pulses. The TVS2200DRVR features a unique feedback mechanism that ensures precise flat clamping during fault events, keeping the clamping voltage below 30 V. This allows system designers to select components with lower voltage tolerance, reducing system costs and complexity without compromising robustness. The device is available in a compact 2 mm × 2 mm SON package, making it ideal for space-constrained applications.
