General-purpose application classification means it is not a dedicated data-line or USB protection part — it is a rail-level suppressor suited for power-supply input stages, distribution buses, and motor-drive AC lines where the standoff voltage aligns with the system rail. ## The clamping chain: what each voltage means for the protected node 53 V reverse standoff is the maximum voltage the TVS sees in normal operation without conducting — the protected rail should sit at or below this level continuously. The clamping voltage at 89.25 V is the decisive number for downstream IC withstand — any protected load must survive a brief 89.25 V spike at up to 17.9 A during the surge event. A single unidirectional channel means it handles one polarity only — for bipolar or AC-line protection a second device in the opposite direction is required.","metaTitle":"Littelfuse 1.5SMC62 TVS Diode, 1500W Peak, 53V Standoff","metaDescription":"Littelfuse 1.5SMC62 unidirectional TVS diode, 53V standoff, 89.25V clamping, 1500W peak pulse.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"55.8V","Voltage - Clamping (Max) @ Ipp":"89.25V","Voltage - Reverse Standoff (Typ)":"53V","Current - Peak Pulse (10/1000µs)":"17.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/118f1b70ec0f0941665a20e5472af60a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC62/alternatives.json"},"ai":{"faq":[{"question":"What replaces the 1.5SMC62?","answer":"The 1.5SMC series remains active but the 62 V nominal standoff bin does not have a direct cross-reference — sourcing an alternative requires checking the nearest standoff voltage (such as 1.5SMC56 or 1.5SMC68) for parametric fit in the protected circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5SMC62","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5SMC62 when reusing this data.
