TI TVS3300DRVR

33VВнутренний переключатель1

Overview

The TVS3300DRVR robustly shunts up to 35 A of IEC 61000-4-5 fault current to protect systemsfrom high power transients or lightning strikes. The device offers a solution to the commonindustrial signal line EMC requirement to survive up to 1 kV IEC 61000-4-5 open circuit voltagecoupled through a 42 Ω impedance. The TVS3300DRVR uses a unique feedback mechanism to ensure preciseflat clamping during a fault, assuring system exposure below 40 V. The tight voltage regulationallows designers to confidently select system components with a lower voltage tolerance, loweringsystem costs and complexity without sacrificing robustness.

The TVS3300DRVR is part of TI’s Flat-Clamp family of surge devices. For more information onthe other devices in the family, see the Device Comparison Table
