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. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here.","metaTitle":"1.5SMC56AT3G Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"1.5SMC56AT3G Littelfuse Zener TVS, 1500W peak pulse, 77V clamp, DO-214AB SMC.
