The DO-214AB (SMC) package is the standard foot print shared across most 1.5 kW TVS families — land pattern, solder joint geometry, and thermal pad design follow the IPC-7351B generic pattern for this body size, so board integration is straightforward.","metaTitle":"Central Semiconductor 1.5SMC91A TR13 PBFREE Zener TVS","metaDescription":"Central Semiconductor 1.5SMC91A TR13 PBFREE unidirectional Zener TVS, 77.8V standoff, 125V clamping, 1.5kW peak pulse, DO-214AB SMC, -65 to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Central Semiconductor Corp","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-65°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Unidirectional Channels":"1","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":"$0.2663","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9191afc3e92f03eb3c6f3d25e0a397c7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC91A%20TR13%20PBFREE/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/central-semiconductor-corp/1.5SMC91A-TR13-PBFREE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/central-semiconductor-corp/1.5SMC91A-TR13-PBFREE when reusing this data.
