The TVS4000 robustly shunts up to 25A of IEC 61000-4-5 fault current to protect systems from high power transients or lightning strikes. The TVS4000 uses a unique feedback mechanism for precise flat clamping during a fault, and is designed for system exposure below 54V. 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 TVS4000 is available in a 1.6mm × 1.6mm footprint which is appropriate for space constrained applications. The extremely low device leakage and capacitance allows a minimal effect on the protected line.

The TVS4000 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
