18V Flat-Clamp Surge Protection Device

18V Flat-Clamp Surge Protection Device - TVS1800
 

Description

The TVS1800 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 TVS1800 uses a unique feedback mechanism to ensure precise flat clamping during a fault, assuring system exposure below 25 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 TVS1800 is available in a small 2 mm × 2 mm SON footprint which is ideal 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 TVS1800 against 5,000 repetitive surge strikes at high temperature with no shift in device performance.

The TVS1800 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.
