3 Description

The TVS0701 device shunts up to 30 A of IEC

61000-4-5 fault current to protect systems from highpower

transients or lightning strikes. The device

survives the common industrial signal line 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, 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 TVS0701 has a

±7-V operating range to enable operation in systems

that require protection against reverse wiring

conditions.

In addition, the TVS0701 is available in a small SON

footprint designed for space constrained applications,

offering a significant size reduction compared to

standard SMA and SMB packages. Low device

leakage and capacitance ensure a minimal effect on

the protected line. To ensure robust protection over

the lifetime of the product, TI tests the TVS0701

against 5000 repetitive surge strikes at 125°C with no

shift in device performance.

The TVS0701 is part of TI's Flat-Clamp family of

surge devices. For a deeper look at the Flat-Clamp

family, refer to the Flat-Clamp Surge Protection

Technology for Efficient System Protection white
