3 Description
The TVS2700 robustly shunts up to 40 A of IEC
61000-4-5 fault current to protect systems from high
power transients or lightning strikes. The device
offers a solution to the common industrial signal line
EMC requirement to survive up to ±1 kV IEC 61000-
4-5 open circuit voltage coupled through a 42 Ω
impedance. The TVS2700 uses a unique feedback
mechanism to ensure precise flat clamping during a
fault, assuring system exposure below 35 V. The tight
voltage regulation allows designers to confidently
select system components with a lower voltage
tolerance, lowering system costs and complexity
without sacrificing robustness.
In addition, the TVS2700 is available in a small 2 mm
× 2 mm SON footprint which is designed for space
constrained applications, offering a 70 percent
reduction in size compared to industry standard SMA
and SMB packages. The extremely 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 TVS2700
against 5,000 repetitive surge strikes at high
temperature with no shift in device performance.
The TVS2700 is part of TI's Flat-Clamp family of
surge devices. For more information on the other
devices in the family, see the Device Comparison
Table.
