The TVS2210 robustly shunts up to 25A of IEC 61000-4-5 fault current to protect systems from high power transients or lightning strikes. The device is designed for the common industrial signal line EMC requirement to survive up to ±1kV IEC 61000-4-5 open circuit voltage coupled through a 42Ω impedance. The TVS2210 uses a unique feedback mechanism for precise flat clamping during a fault, allowing system exposure below 30V. The tight voltage regulation allows designers to confidently select system components with a lower voltage tolerance, lowering system costs and complexity without sacrificing robustness.
