The 1.5SMC56AT3G: It clamps transients on a 47.8V nominal rail to 77V maximum, with a breakdown voltage window starting at 53.2V minimum. The 19.5A peak pulse current rating at the standard 10/1000µs pulse defines the surge it can absorb — useful for protecting downstream components on 48V telecom or industrial DC buses where the steady-state voltage sits at 47.8V or below.
