At full rated current (16.3A), the clamp voltage reaches 92V, which sets the maximum voltage the downstream components must survive. With a unidirectional configuration (single channel), it protects one polarity rail against positive-going transients. ## AEC-Q101 qualification: what the automotive grade certifies For a Tier-1 or OEM PPAP submission, the AEC-Q101 report — along with the Vishay manufacturing site qualification — satisfies the component-level reliability evidence required by IATF 16949. The 'HE3' suffix in the order code indicates the automotive-grade screening and lead-free termination finish. ## Obsolete lifecycle — sourcing through independent channels Vishay has marked the 1.5KE68AHE3/51 as Obsolete. The DO-201AA axial package is a standard footprint, so a pin-compatible replacement from the same TransZorb family (e.g., the 1.5KE68A series) can be cross-referenced by clamp voltage and standoff, but the exact AEC-Q101 grade and Vishay part number are lot-specific.","metaTitle":"1.5KE68AHE3/51 Vishay TVS, 1500W, 58.1V Standoff, Axial","metaDescription":"Obsolete 1.5KE68AHE3/51 Zener TVS diode by Vishay, 1500W peak pulse, 58.1V standoff, AEC-Q101 qualified.
