Texas Instruments  TVS1401DRBR

The TVS1401 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 TVS1401 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 TVS1401 has a ±14 V operating range to enableoperation in systems that require protection against reverse wiring conditions.

In addition, the TVS1401 is available in a small SON footprint which is designed forspace constrained applications, offering a significant size reduction compared to standard SMA andSMB packages. 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 TVS1401 against 5,000repetitive surge strikes at 125°C with no shift in device performance.

The TVS1401 is part of TI’s Flat-Clamp family of surge devices. For a deeper look at theFlat-Clamp family, refer to Flat-Clamp Surge Protection Technology for Efficient SystemProtection white paper.
