Once a surge pushes the line above the 71.3 V minimum breakdown, the TVS avalanches and clamps. The 104 V clamping ceiling at peak pulse current is what the downstream IC sees during the event — so you size the IC's absolute-maximum input rating with headroom above 104 V, not just below 64.1 V. The AEC-Q101 qualification means this part passed the automotive stress suite — humidity, temperature cycling, and surge life — and is design-qualified for safety-critical modules. For an engine-compartment ECU that sees 125°C ambient, the 150°C TJ ceiling still leaves margin. ## Bidirectional, SMC package, tape-and-reel The CA suffix confirms a single bidirectional TVS — it clamps both positive and negative transients on the same node, which is what you need on an unsymmetrical power rail that floats or has a shared ground reference. The DO-214AB (SMC) surface-mount package with tape-and-reel packaging fits standard automotive pick-and-place lines; confirm the land pattern against the DO-214AB footprint in the datasheet before committing to the layout, especially for thermal pad termination. ## Active lifecycle — sourcing against an RFQ The part carries Active status from Vishay General Semiconductor — Diodes Division.","metaTitle":"Vishay 1.5SMC75CAHM3/H TVS Diode, 1500W Peak Pulse","metaDescription":"Vishay 1.5SMC75CAHM3/H, AEC-Q101 bidirectional TVS diode, 1500W peak pulse, 64.1V standoff.
