For a BOM line that calls out this exact Vishay order code, the supply path runs through independent surplus and broker channels. ## What the 1500W rating means for the protection window In a 12V or 24V automotive rail, the 97.2V reverse standoff sits well above the nominal bus voltage so the diode does not conduct during normal operation, while the 108V minimum breakdown ensures the avalanche triggers before the downstream silicon sees damaging overvoltage. The 173V maximum clamping voltage at 8.7A is the worst-case voltage the protected load sees during a surge — this is the figure to compare against the absolute-maximum rating of the IC or module being protected. ## Automotive qualification and temperature envelope Part of the TransZorb® series and qualified to AEC-Q101, the automotive-grade discrete semiconductor reliability standard. Single bidirectional channel — one device clamps both polarities, simplifying the BOM for AC-coupled or bipolar rails where the surge can swing either direction.","metaTitle":"Vishay 1.5KE120CHE3/73 TVS Diode, 1500W, Bidirectional","metaDescription":"Obsolete Vishay 1.5KE120CHE3/73 bidirectional TVS diode, 1500W peak pulse, 97.2V standoff, AEC-Q101.
