When selecting a TVS for a power supply bus or motor drive input, the 10/1000 µs rating is the governing surge-survivability number, not a raw power figure. ## How the standoff and clamping voltages set protection headroom The reverse standoff of 64.1 V defines the continuous working voltage the diode blocks in normal operation. The breakdown minimum of 71.3 V is where conduction begins, and the clamping maximum of 103 V at 14.8 A is where the device limits voltage under a full-rated surge event — a 31.7 V clamping margin above the standoff. For a 72 V nominal bus this gives roughly 40% headroom above the working voltage before the TVS enters conduction. ## Temperature grade and the DO-214AB package The DO-214AB (SMCJ) package is the standard SMC footprint for this power class — compatible with standard solder profiles and reflow-capable board assembly. Surface-mount termination supports automated pick-and-place.","metaTitle":"1.5SMC75A TVS Diode, 103V Clamping, 14.8A Peak","metaDescription":"Littelfuse 1.5SMC75A unidirectional Zener TVS, 64.1V standoff, 103V clamping, 14.8A peak pulse at 10/1000µs, DO-214AB SMC package, -55 to 150°C junction","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","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)":"71.3V","Voltage - Clamping (Max) @ Ipp":"103V","Voltage - Reverse Standoff (Typ)":"64.1V","Current - Peak Pulse (10/1000µs)":"14.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4a8a4359c4139865ec4feb6a6da8698b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC75A/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5SMC75A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5SMC75A when reusing this data.
