If the circuit sees bidirectional or AC-coupled transients, a dual-polarity TVS or back-to-back stack would be needed instead. ## Standoff, breakdown, and clamping — what the voltage ratings mean for your rail 58.1 V reverse standoff is the working voltage — the maximum DC rail this part sees continuously without conducting. For a 48 V nominal system that sits at 56 V under normal charge, this gives roughly 3.5 V of headroom before the device approaches its breakdown region. 64.6 V minimum breakdown is where the Zener junction begins conducting — at this point the suppressor starts clamping. The 1.5SMC68AS is classified at the 68 V nominal rating (the 68 in the part number), placing the breakdown band around 64.6 V minimum for this specific unit. ## Junction temperature and assembly Supplied on tape and reel in the SMC package — the TO-263-derived DO-214AB foot print is compatible with standard SMT lines and hot-air or IR reflow profiles. No power-line protection flag means this is a general-purpose signal-line or local rail clamp, not a dedicated AC mains protection device.","metaTitle":"1.5SMC68AS_R1_00001 Zener TVS 1500W 92V Clamping","metaDescription":"Panjit 1.5SMC68AS_R1_00001 unidirectional Zener TVS in DO-214AB SMC, 1500W peak pulse, 58.1V standoff, -55°C to 150°C junction.

Parts binned to adjacent standoff voltages (e.g., the 1.5SMC62A through 1.5SMC75A range) are footprint-compatible and share the same clamping performance class — the selection is driven by the standoff voltage matching your rail. The part number suffix and revision (_R1_00001) indicates a Panjit-specific variant; confirm the exact voltage band and packing variant before cross-sourcing."},{"question":"Can I use this 1.5SMC68AS_R1_00001 on a 24 V industrial rail?","answer":"The 58.1 V standoff gives comfortable headroom on a 24 V nominal rail, but the minimum breakdown of 64.6 V means the part will not begin clamping until a surge exceeds roughly 2.7× the working voltage — if the threat profile includes sub-64 V transients on a sensitive 24 V rail, a lower-voltage TVS (such as a 1.5SMC30A) would provide earlier clamping and better load protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMC68AS_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMC68AS_R1_00001 when reusing this data.
