The bidirectional configuration simplifies layout by eliminating polarity concerns on AC-coupled or floating lines. onsemi has marked the P6SMB16CAT3 as Obsolete. This means the manufacturer no longer produces the part and has no scheduled last-time-buy window. New designs should not specify this order code. For existing BOMs, the part can be sourced through independent distribution. The DO-214AA (SMB) package is common, so cross-shipping a replacement in the same footprint is straightforward if a direct substitute is identified. The capacitance of 610 pF at 1 MHz is low enough for most signal lines but may load high-speed data buses above 1 Mbps — verify signal integrity if used on CAN FD or LIN.","metaTitle":"P6SMB16CAT3 onsemi Zener TVS Diode – Obsolete, Sourcing Info","metaDescription":"P6SMB16CAT3 onsemi bidirectional Zener TVS, 600W peak pulse, AEC-Q101, DO-214AA (SMB).

A functionally compatible alternative in the same DO-214AA (SMB) package is the P6SMB16A (unidirectional) or P6SMB16CA (bidirectional) from onsemi or Littelfuse, but confirm the breakdown and clamping voltages match your protection threshold. The P6SMB16CAT3 is bidirectional; the P6SMB16A is unidirectional, so the circuit topology must allow for that difference."},{"question":"Is P6SMB16CAT3 automotive qualified?","answer":"Yes, the series is listed as Automotive, AEC-Q101, meaning it has passed the stress tests required for automotive-grade components: high-temperature reverse bias, temperature cycling, and ESD robustness per AEC-Q101."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/P6SMB16CAT3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/P6SMB16CAT3 when reusing this data.
