It clamps transients to 19.9V maximum at the 75.3A peak pulse current, making it a fit for 12V rail protection in general-purpose circuits. The DO-214AB (SMC) package is surface-mount and the part ships on Tape & Reel. ## Breakdown and Clamping – Key Parametric Decisions The 13.3V minimum breakdown voltage sets the threshold where the TVS begins conducting; below that the protected line sees only leakage. The 19.9V maximum clamping voltage defines the worst-case voltage the downstream circuitry must survive — a 12V rail with 20% tolerance margins comfortably above 19.9V. The 75.3A peak pulse current (Ipp) at the 10/1000µs waveform is the surge capacity; a 1500W TVS on a 12V rail can absorb transient energy well above typical industrial surge requirements. ## Sourcing – Tape & Reel, Surface Mount","metaTitle":"SMCJ12AE3/TR13 TVS Diode – Microchip, 1500W, 12V Standoff","metaDescription":"Active-production SMCJ12AE3/TR13 Zener TVS from Microchip. 1500W peak pulse, 12V reverse standoff, 13.3V min breakdown, 75.3A Ipp. Sourced per RFQ.","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":"SMCJ12","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)":"13.3V","Voltage - Clamping (Max) @ Ipp":"19.9V","Voltage - Reverse Standoff (Typ)":"12V","Current - Peak Pulse (10/1000µs)":"75.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6750","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is SMCJ12AE3/TR13 unidirectional or bidirectional?","answer":"It is a single-channel unidirectional Zener TVS diode."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ12AE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ12AE3-TR13 when reusing this data.
