The DO-214AB (SMC) package is a standard surface-mount footprint, reworkable with hot air and compatible with lead-free reflow profiles. ## Key ratings that define the protection window The 48V reverse standoff voltage is the maximum DC or AC peak voltage the TVS can withstand without conducting — match this to your rail voltage. The minimum breakdown voltage is the threshold where the device starts to avalanche; below this the circuit sees no leakage. Operating junction temperature spans -65°C to 150°C, covering military and automotive under-hood environments without derating at the cold end. Power line protection is not supported — this is a unidirectional device for DC rails only, not for AC mains. This removes the obsolescence risk for new designs and allows repeat orders without last-time-buy pressure.","metaTitle":"SMCJ48AE3/TR13 – 48V Zener TVS Diode, 1.5kW, DO-214AB","metaDescription":"Microchip Technology SMCJ48AE3/TR13 Zener TVS diode: 48V reverse standoff, 53.3V breakdown, 77.4V clamp, 1.5kW peak pulse, DO-214AB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"SMCJ48","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"53.3V","Voltage - Clamping (Max) @ Ipp":"77.4V","Voltage - Reverse Standoff (Typ)":"48V","Current - Peak Pulse (10/1000µs)":"19.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5550","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ48AE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ48AE3-TR13 when reusing this data.
