Vishay's TransZorb series is RoHS-compliant per the standard HE3 suffix designation. For PPAP, IMDS, or full AEC-Q101 test report requests, the qualification data package is available through Vishay's automotive documentation portal."},{"question":"What is the 1.5SMC39CAHE3/9AT's clamping performance for a 24 V automotive bus?","answer":"The reverse standoff voltage is 33.3 V, so it sits idle below the nominal 24 V rail. Breakdown occurs at a minimum of 37.1 V. For a 24 V bus transient that reaches 60 V, the TVS clamps to 53.9 V, protecting downstream 60 V-rated silicon with margin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC39CAHE3-9AT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC39CAHE3-9AT when reusing this data.
