When a surge exceeds the 71.1 V minimum breakdown voltage, the diode starts conducting, clamping the transient to a maximum of 103 V while shunting up to 3.9 A of peak pulse current in the 10/1000 µs waveform. The 400 W peak pulse power rating defines the energy-handling capability for short-duration transients — a 64 V bus in industrial or telecom equipment sees repetitive surges from inductive load switching or lightning-coupled events, and this diode absorbs them without exceeding its thermal limit. ## Package, mounting, and temperature range Housed in a DO-214AC (SMA) package with surface-mount termination, the SMAJ64A-13 fits standard reflow profiles. The SMA footprint is common across TVS diodes in this power class — the same pad layout serves multiple voltage variants, so a BOM change from 64 V to a different standoff does not require a board spin. At the high end, the leakage current increases but the clamping voltage stays within the rated limit — the 150°C ceiling matches typical derating curves for 400 W TVS devices.","metaTitle":"SMAJ64A-13 TVS Diode, 64V Standoff, 103V Clamp, DO-214AC","metaDescription":"SMAJ64A-13 TVS Zener diode from Diodes Inc, 64V reverse standoff, 103V clamping, 400W peak pulse power, DO-214AC (SMA) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","lifecycle_stage":"eol_hot","Power - Peak Pulse":"400W","Base Product Number":"SMAJ64","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMA","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"71.1V","Voltage - Clamping (Max) @ Ipp":"103V","Voltage - Reverse Standoff (Typ)":"64V","Current - Peak Pulse (10/1000µs)":"3.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a6e414533ed6f0f7c15ae6d19d66ae3c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMAJ64A-13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMAJ64A-13 when reusing this data.
