Built for automotive environments: the series carries AEC-Q101 qualification, meaning it passed the stress and reliability screens required for under-hood and chassis-domain electronics. Vishay has marked the 1.5KE15HE3/73 as obsolete. No official successor order code is listed by the manufacturer — the replacement path is a functionally equivalent TVS in the same 1.5KE family with matching standoff and clamping specs, but the specific /73 packaging (tape and box, axial) may not carry over. ## Package and board fit Through-hole axial package — DO-201AA (DO-27) body, 1.5KE supplier device package code. The axial leads suit point-to-point wiring or through-hole PCB mounting; the lead diameter and body length match the standard DO-201 footprint, so a replacement part in the same package drops in without a board spin. Supplied in tape and box (TB) format — the /73 suffix identifies this packaging variant. The axial leads are taped for automatic insertion but boxed rather than reeled; verify feeder compatibility if using automated assembly.","metaTitle":"1.5KE15HE3/73 Vishay TVS, 1.5kW, 12.1V Standoff","metaDescription":"Vishay 1.5KE15HE3/73 automotive TVS diode, 1500W peak pulse, 12.1V standoff, AEC-Q101, obsolete.
