The DO-214AB SMC package is the standard industry footprint for this series; it lands on the same pad geometry as competitor parts in the 1.5SMC family, so the board layout carries over without spin.","metaTitle":"Panjit 1.5SMC91CA_R1_00001 TVS Zener, 125V clamp","metaDescription":"Panjit 1.5SMC91CA_R1_00001 unidirectional TVS Zener, 77.8V standoff, 125V clamping @ 12A peak pulse, 1.5kW peak, -55 to 150°C, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International 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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Voltage - Breakdown (Min)":"86.5V","Voltage - Clamping (Max) @ Ipp":"125V","Voltage - Reverse Standoff (Typ)":"77.8V","Current - Peak Pulse (10/1000µs)":"12A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9b1a0293ff65c6af80e9dd770f371944.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What voltage does the 1.5SMC91CA_R1_00001 actually clamp at?","answer":"Maximum clamping voltage is 125 V measured at the 12 A peak pulse condition (10/1000 µs). The reverse standoff sits at 77.8 V typical, so the diode stays off the line until a transient exceeds that threshold — the 86.5 V minimum breakdown rating is the floor at which it begins conducting in the Zener region."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMC91CA_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/1.5SMC91CA_R1_00001 when reusing this data.
