For a 38.1V standoff rail, the clamping voltage hits 67.8V at 22.1A peak pulse current, so the TVS holds the line voltage below the downstream component's abs-max rating during a surge. The DO-201AA axial package with through-hole mounting is a standard footprint for board-level transient protection in power supplies, telecom interfaces, and industrial control inputs. ## Obsolete — sourcing reality for the 1.5KE47C-E3/54 The DO-201AA axial package and bidirectional Zener topology are common enough that a parametric search for a 1500W, 38.1V standoff bidirectional TVS in the same package will yield functional equivalents — but pin-compatibility is package-defined, not guaranteed by the replacement part's specs. This covers the full industrial and automotive under-hood ambient range, with margin for self-heating during repetitive surge events. The 175°C Tj max is typical for silicon TVS diodes — derate the peak pulse power above 25°C per the datasheet curve to stay within the SOA.","metaTitle":"1.5KE47C-E3/54 Vishay TransZorb TVS, 1500W, 38.1V Standoff","metaDescription":"Vishay 1.5KE47C-E3/54 bidirectional Zener TVS, 1500W peak pulse, 38.1V standoff, DO-201AA axial.
