No official replacement has been announced. For a functionally equivalent 600 W bidirectional TVS in DO-214AA with similar standoff and clamp voltages, look at the onsemi P6SMB68A (unidirectional) or the SMBJ58A series, but verify the breakdown voltage and AEC-Q101 grade against your application. The P6SMB68CAT3 is available through independent surplus channels; request a quote for current lots."},{"question":"What is the difference between P6SMB68CAT3 and P6SMB68A?","answer":"The P6SMB68CAT3 is a bidirectional device (clamps both polarities) with a 58.1 V reverse standoff and 92 V clamp, while the P6SMB68A is a unidirectional version with a 58.1 V reverse standoff but a slightly different breakdown voltage range. The bidirectional CAT3 is preferred for AC-coupled or floating lines where polarity is unknown."},{"question":"Can P6SMB68CAT3 be used in automotive applications?","answer":"Yes, it is AEC-Q101 qualified, which certifies it for automotive-grade reliability including temperature cycling and ESD stress per the AEC-Q101 standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/P6SMB68CAT3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/P6SMB68CAT3 when reusing this data.
