For a 6.05V reverse standoff, the diode stays off below that voltage; once the transient pushes past the 6.75V minimum breakdown, it starts conducting and clamps hard at 11.7V. ## Field-replaceable axial package The DO-201AA (DO-27) axial leaded package is through-hole — you can swap it on site with a soldering iron and a pair of cutters. No hot-air station, no reflow profile. The body is marked with the part number and polarity band, so orientation is clear even under a work light. The 1.5KE package suffix is the standard DO-201 footprint; it fits the same board holes as any 1.5KE-series TVS. ## Obsolete — sourcing through independent channels Vishay lists this part as obsolete. For a BOM that already uses this TVS, the board footprint and electrical ratings are fixed; a functional replacement would require a different order code and likely a different package, meaning a board spin.","metaTitle":"1.5KE7.5HE3/54 Vishay TVS, 1500W, 6.05V Standoff, DO-201","metaDescription":"Vishay 1.5KE7.5HE3/54 TransZorb TVS, 1500W peak pulse, 6.05V reverse standoff, 11.7V clamp.
