3 Description
The TVS5800 robustly shunts up to 25A of IEC
61000-4-5 fault current to protect systems from
high power transients or lightning strikes. The
TVS5800 uses a unique feedback mechanism
to maintain precise flat clamping during a fault,
supporting system exposure below 76V. 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 TVS5800 is available in a 1.6mm
x 1.6mm footprint which is designed for space
constrained applications. The extremely low device
leakage and capacitance allows a minimal effect on
the protected line.
The TVS5800 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
