TVS1801 18V Bidirectional Surge Protection Device

Texas Instruments TVS1801 18V Bidirectional Surge Protection Device shunts up to 30A of IEC 61000-4-5 fault current to protect systems from high-power transients or lightning strikes. The device survives the common industrial signal line EMC requirement of 1kV IEC 61000-4-5 open circuit voltage coupled through a 42Ω impedance. The TVS1801 uses a feedback mechanism to ensure precise flat clamping during a fault, keeping system exposure lower than traditional TVS diodes. The tight voltage regulation allows designers to confidently select system components with a lower voltage tolerance, lowering system costs and complexity without sacrificing robustness. The Texas Instruments TVS1801 has a ±18V operating range to enable operation in systems that require protection against reverse wiring conditions.
