It clamps a 64.1 V reverse standoff to 104 V maximum at 14.6 A peak pulse current (10/1000 µs waveform). The Zener breakdown voltage is specified at 71.3 V minimum. The single unidirectional channel provides no power-line protection — it is designed for signal or low-voltage DC rail clamping in automotive environments. ## What the ratings mean for a BOM decision The 64.1 V reverse standoff (VRWM) is the maximum DC voltage the TVS can sit across without conducting — a 48 V nominal automotive bus with transients stays below this threshold. The 104 V clamping voltage (VC) at 14.6 A peak pulse current defines the voltage the downstream circuitry must survive; a 100 V-rated MOSFET on the rail has 4 V of margin at the clamp point. ## Sourcing an obsolete part — what to expect For a BOM line that requires this exact AEC-Q101 TVS in the DO-201AA footprint, the sourcing path is a per-quote basis through independent distribution.","metaTitle":"1.5KE75AHE3/51 Vishay TVS, 1500W, 64.1V, DO-201AA","metaDescription":"Vishay 1.5KE75AHE3/51 TVS diode, 1500W peak pulse, 64.1V standoff, AEC-Q101, DO-201AA axial.
