Description
AI
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 TI’s Flat-Clamp family of surge devices. For more information on the other devices in the family, see theDevice Comparison Table
