The 67.8V clamp ceiling keeps the protected node below the 100V absolute maximum of most automotive-rated ECUs and sensors. ## Obsolete — sourced through surplus channels Vishay lists this part as Obsolete. The through-hole DO-201AA axial package is a legacy footprint. Board-level replacement is straightforward if the original BOM position accepts this form factor. Confirm the mating hole pattern and lead spacing before committing.","metaTitle":"Vishay 1.5KE47HE3/54 TVS, 1500W, 38.1V Standoff, AEC-Q101","metaDescription":"Obsolete Vishay 1.5KE47HE3/54 1500W unidirectional TVS diode.
