The -55°C to 150°C junction temperature range covers industrial and outdoor deployment — no derating concern at 85°C ambient, though the 600W rating assumes a 25°C starting point and derates linearly above that per the datasheet curve. This is a signal-line TVS, not a mains protector — the spec explicitly flags no power line protection, so it belongs on DC buses, I/O ports, or communication interfaces where a 120V rail needs bidirectional clamping. ## DO-214AA SMB — board-fit and package note Housed in the DO-214AA (SMB) surface-mount package, the footprint matches the industry-standard SMB land pattern — same pad geometry as the SMA and SMC siblings, just scaled to the 600W power dissipation. Supplied on Tape & Reel, the part is pick-and-place ready for high-volume assembly. The bidirectional construction means no polarity marking to verify during placement — either orientation clamps both polarities.","metaTitle":"SMBJ120CA-13-F Diodes Inc TVS, 120V, 600W, DO-214AA","metaDescription":"SMBJ120CA-13-F Zener TVS diode, 600W peak pulse, 120V reverse standoff, 193V clamp, DO-214AA SMB.

The breakdown voltage range starts at 133V minimum, so the device begins conducting well before the rail reaches the clamp ceiling — the protection window is about 60V between breakdown onset and full clamp."},{"question":"What compliance documentation does Diodes Incorporated provide for SMBJ120CA-13-F?","answer":"The part carries standard RoHS and REACH compliance from Diodes Incorporated. No UL or IEC certification is listed in the spec record for this order code — typical for a semiconductor TVS where the package-level safety approval is covered by the manufacturer's overall quality system, not a per-part listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMBJ120CA-13-F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMBJ120CA-13-F when reusing this data.
