For a BOM that requires this exact order code, the sourcing path is a last-time-buy or spot-market procurement. Through-hole DO-201AA (DO-27) axial package — the leads are formed for through-hole insertion on a standard 0.4-inch lead spacing. The 1.5KE package suffix indicates the same body size as the rest of the 1.5KE series, so existing PCB footprints for a 1.5KE18 TVS accept this part without layout change. The wide junction temperature margin means derating for high ambient is minimal at the 1500W peak pulse rating.","metaTitle":"Vishay 1.5KE18CHE3/54 TVS, 1500W, 14.5V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE18CHE3/54 Zener TVS diode, 1500W peak pulse, 14.5V reverse standoff, AEC-Q101, obsolete.
