Single-channel rail-to-rail ESD clamp for HDMI
It clamps transients to the supply rails with a peak pulse power rating of 40W, a reverse standoff voltage of 5.5V (max), and a clamping voltage of 14V at 2.5A (8/20µs).
The 0402 (1006 Metric) package is tiny — 1.0 mm x 0.6 mm — so the pad layout needs to be tight and the stencil aperture matched to avoid solder bridging. It's a two-pin device with a clear orientation mark, but at this size you'll want a microscope to confirm polarity after reflow. The low thermal mass means it reflows quickly; a standard lead-free profile with a 260°C peak works fine. Just watch the placement accuracy — a 0.1 mm shift and the part can tombstone.
