The TVS3300 robustly shunts up to 35 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 TVS3300 uses a unique feedback mechanism to ensure precise
flat clamping during a fault, assuring system exposure below 40 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 TVS3300 is available in small 1 mm × 1.1 mm WCSP and 2 mm × 2 mm SON
footprints which are ideal for space constrained applications, offering up to a 90 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 TVS3300 against 4000 repetitive surge strikes at
high temperature with no shift in device performance.
The TVS3300 is part of TIs Flat-Clamp family of surge devices. For more information on
