The SQ-MELF B package is a hermetic surface-mount ceramic body — no plastic encapsulation, so moisture sensitivity is not a concern. This package is common in military, aerospace, and downhole applications where outgassing and humidity resistance matter. ## Voltage thresholds and thermal envelope Breakdown voltage starts at 13.54 V minimum, giving margin above the 11.4 V standoff before the device enters avalanche. The clamp at 22.05 V is the let-through voltage the protected circuit must survive — a 12 V-rated rail needs a downstream capacitor or TVS with a higher hold-off to ride through the pulse. At 175°C the leakage current rises, but the silicon still clamps — this is a part for engine bays, satellite thermal vacuum, or oil-well logging tools where the ambient hits 150°C+. ## Active production — no last-time-buy pressure Lifecycle status is Active. No PCN, no EOL notice on this base number.","metaTitle":"1N6110US Zener TVS Diode – 500W Bidirectional, SQ-MELF","metaDescription":"1N6110US bidirectional Zener TVS diode, 500W peak pulse power, 11.4V standoff, 22.05V clamp.

That is the energy the device can absorb in a single surge event before the junction temperature exceeds the rating."},{"question":"Is 1N6110US RoHS compliant?","answer":"The evidence does not list a RoHS compliance statement. The SQ-MELF package is hermetic ceramic — typically RoHS-compliant by construction, but confirm the specific date-code lot certificate if your compliance audit requires a documented statement."},{"question":"Why is 1N6110US considered a bidirectional TVS diode?","answer":"The datasheet lists one bidirectional channel. A bidirectional Zener TVS clamps both positive and negative surges symmetrically — the breakdown voltage is the same magnitude in both directions. This lets a single device protect a signal line that swings above and below ground, like a differential pair or an AC-coupled line."},{"question":"Can 1N6110US be used for AC line protection?","answer":"Power line protection is explicitly listed as 'No'. This part is designed for DC signal or low-voltage DC rail protection, not for rectified mains or 50/60 Hz AC line surge suppression. For AC mains protection, look at a dedicated MOV or gas discharge tube."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6110US","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6110US when reusing this data.
