TVS3301 (ACTIVE)

33 V Bidirectional Flat-Clamp Surge Protection Device

 

Description

The TVS3301 device shunts up to 27 A of IEC 61000-4-5 fault current to protect systems from high-power transients or lightning strikes. The device survives the common industrial signal line EMC requirement of 1-kV IEC 61000-4-5 open circuit voltage coupled through a 42-Ω impedance. The TVS3301 uses a feedback mechanism to ensure precise flat clamping during a fault, keeping system exposure lower than traditional TVS diodes. The tight voltage regulation allows designers to confidently select system components with a lower voltage tolerance, lowering system costs and complexity without sacrificing robustness. The TVS3301 has a ±33-V operating range to enable operation in systems that require protection against reverse wiring conditions.

In addition, the TVS3301 is available in a small SON footprint designed for space constrained applications, offering a significant size reduction compared to standard SMA and SMB packages. 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 TVS3301 against 5000 repetitive surge strikes at 125°C with no shift in device performance.

The TVS3301 is part of TI’s Flat-Clamp family of surge devices. For a deeper look at the Flat-Clamp family, refer to the Flat-Clamp Surge Protection Technology for Efficient System Protection white paper.
