That 1500W rating means it can absorb a 33A transient pulse before the clamping voltage hits 45.4V — a solid margin for protecting 24V DC rails in industrial or telecom gear where the nominal bus sits at 28V or below. ## Active production, no end-of-life signal","metaTitle":"SMCJ28AE3/TR13 TVS Diode – 1500W, 28V, Unidirectional","metaDescription":"SMCJ28AE3/TR13 from Microchip: 1500W peak pulse power, 28V reverse standoff, unidirectional Zener TVS in 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":"SMCJ28","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)":"31.1V","Voltage - Clamping (Max) @ Ipp":"45.4V","Voltage - Reverse Standoff (Typ)":"28V","Current - Peak Pulse (10/1000µs)":"33A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5550","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMCJ28AE3%2FTR13/alternatives.json"},"ai":{"faq":[{"question":"What is the peak pulse power of SMCJ28AE3/TR13?","answer":"The SMCJ28AE3/TR13 is rated for 1500W peak pulse power under the 10/1000µs waveform. This is the standard 1.5kW rating for the SMCJ family, suitable for clamping high-energy transients on 24V DC rails."},{"question":"Is SMCJ28AE3/TR13 a unidirectional TVS diode?","answer":"Yes, it has one unidirectional channel. It clamps positive overvoltage transients relative to ground; for negative-going spikes you would need a series blocking diode or a bidirectional TVS."},{"question":"What is the difference between SMCJ28AE3/TR13 and SMCJ28A?","answer":"The SMCJ28A is the base part number without the - lead-free finish suffix or the /TR13 reel packaging code. Electrically they are identical: same 1500W peak pulse power, same 28V reverse standoff, same unidirectional Zener construction. The - suffix on the SMCJ28AE3/TR13 confirms RoHS compliance; the /TR13 suffix specifies 13-inch tape-and-reel delivery. If your BOM calls for SMCJ28A, the SMCJ28AE3/TR13 is a drop-in replacement as long as you can accept the lead-free finish and the reel format."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ28AE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ28AE3-TR13 when reusing this data.
