The reverse standoff voltage is 70V, meaning the diode stays off below that rail voltage and only starts conducting when the transient exceeds the minimum breakdown of 77.8V. For a 48V or 60V DC bus, this gives enough margin to avoid nuisance triggering while still catching overvoltages before they reach the load. ## Package and placement Housed in a DO-214AC (SMA) surface-mount package, the SMAJ70CA-13-F shares the same footprint as other SMA-packaged TVS diodes — a standard two-pad layout with the cathode marked by a band. The package is rated for reflow soldering and ships in Tape & Reel (Cut Tape also available), so it feeds straight into a pick-and-place line. No power line protection feature is listed — this is a general-purpose transient suppressor for signal or low-power DC rails, not a primary AC mains protector. The base product number is SMAJ70, so the -13-F suffix denotes the Tape & Reel packaging variant. If you need a different reel quantity or cut tape, the same die in the same package is orderable under the base number with a different suffix.","metaTitle":"SMAJ70CA-13-F Diodes Inc TVS Diode, 400W, Bidirectional, SMA","metaDescription":"SMAJ70CA-13-F Zener TVS diode from Diodes Inc. 400W peak pulse power, bidirectional, 70V reverse standoff, 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) Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"400W","Base Product Number":"SMAJ70","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMA","Voltage - Breakdown (Min)":"77.8V","Voltage - Clamping (Max) @ Ipp":"113V","Voltage - Reverse Standoff (Typ)":"70V","Current - Peak Pulse (10/1000µs)":"3.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0270111b098582f24c0b7d28e81a77ac.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to SMAJ70CA-13-F in this Circuit Protection family?","answer":"Within the SMAJ series, the unidirectional version (SMAJ70A-13-F) is pin-compatible — same package, same voltage ratings, but protects only one polarity.
