TVS1801DRBR Description

Short technical summary and product information.

The TVS1801DRBR is an 18V bidirectional flat-clamp surge protection device designed by Texas Instruments. It provides robust protection against high-power transients and lightning strikes, with a peak pulse power rating of 825W (8/20μs). The device features a precise flat clamping voltage of 27.4V at 30A, ensuring system exposure remains low during fault conditions.

The TVS1801DRBR offers a standoff voltage of ±18V, a minimum breakdown voltage of 23.35V, and typical capacitance of 65pF. It can handle surge currents of 30A (8/20μs) per IEC 61000-4-5 and 4.5A (10/1000μs) per IEC61643-321. Leakage current is extremely low at 0.4nA typical at 27°C, rising to 280nA maximum at 85°C.

The device uses a feedback mechanism to achieve flat clamping, which allows designers to use lower-voltage system components with confidence. It is bidirectional, enabling protection against bipolar signaling or miswiring conditions. The TVS1801DRBR also integrates level 4 IEC 61000-4-2 ESD protection.

Packaged in a small 3mm x 3mm SON (DFN3030) footprint, the TVS1801DRBR saves significant board space compared to traditional SMA and SMB packages. It is surface mount and rated for industrial temperature ranges.
