With an 81V reverse standoff voltage and a 90V minimum breakdown, it protects a nominal 72V or 80V rail — the clamping voltage is 144V at the 10.4A peak pulse current (10/1000µs waveform), so the protected circuit must survive a 144V transient before the TVS clamps. ## Lifecycle reality — obsolete, sourced through independent channels No official pin-compatible successor is recorded from Vishay; a parametric replacement would require verifying the standoff voltage, clamping voltage, and package footprint against the application's transient protection requirements.","metaTitle":"Vishay 1.5KE100HE3/54 TVS Diode, 1500W, 81V Standoff","metaDescription":"Obsolete Vishay 1.5KE100HE3/54 automotive TVS, AEC-Q101, 1500W peak pulse, 81V standoff, DO-201AA.
