The TVS0701 device shunts up to 30 A of IEC 61000-4-5 fault current to protect systemsfrom high-power transients or lightning strikes. The device survives the common industrial signalline EMC requirement of 1-kV IEC 61000-4-5 open circuit voltage coupled through a 42-Ω impedance.The TVS0701 uses a feedback mechanism to ensure precise flat clamping during a fault, keepingsystem exposure lower than traditional TVS diodes. The tight voltage regulation allows designers toconfidently select system components with a lower voltage tolerance, lowering system costs andcomplexity without sacrificing robustness. The TVS0701 has a ±7-V operating range to enableoperation in systems that require protection against reverse wiring conditions.
In addition, the TVS0701 is available in a small SON footprint designed for spaceconstrained applications, offering a significant size reduction compared to standard SMA and SMBpackages. Low device leakage and capacitance ensure a minimal effect on the protected line. Toensure robust protection over the lifetime of the product, TI tests the TVS0701 against 5000repetitive surge strikes at 125°C with no shift in device performance.
The TVS0701 is part of TIs Flat-Clamp family of surge devices. For a deeper look at theFlat-Clamp family, refer to the Flat-Clamp Surge Protection Technology for Efficient SystemProtection white paper.
