The bidirectional configuration — a single device clamps both polarities — simplifies board layout on AC-coupled or floating signal lines where the transient polarity is unknown. ## Clamping voltage and breakdown margin With a 7.5V reverse standoff voltage (working voltage), the diode remains transparent to the protected rail under normal conditions. The minimum breakdown voltage of 8.33V provides a guard band above the standoff, ensuring the device does not conduct leakage current during steady-state operation. The 400W peak pulse power rating is specified with a 10/1000µs waveform per industry standard. For shorter-duration transients (e.g. 8/20µs per IEC 61000-4-5), the device can absorb significantly higher peak power — a common derating practice in automotive ECU designs where the threat model includes fast ESD and EFT events. ## DO-214AC SMA package and board integration Housed in the standard DO-214AC (SMA) package, the SMAJ7.5CAQ-13-F mounts on the PCB with a surface-mount footprint shared across the SMAJ series. The SMA package body measures roughly 4.6 mm x 2.8 mm, fitting into tight layouts on engine-control or sensor modules where board space is at a premium. The junction operates from -55°C to 150°C, covering the full automotive temperature envelope. No power line protection is claimed — this is a pure transient suppressor, not a series element, so it sits in parallel with the protected load. ## Active production and sourcing posture The SMAJ series includes other voltage variants sharing the same package and footprint, but the 7.5V bidirectional automotive grade is a distinct BOM line.","metaTitle":"SMAJ7.5CAQ-13-F Diodes Inc TVS Diode, 400W, Bidirectional","metaDescription":"SMAJ7.5CAQ-13-F is an AEC-Q101 qualified automotive Zener TVS diode from Diodes Inc. 400W peak pulse power, 7.5V standoff, bidirectional, 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","Grade":"Automotive","Series":"-","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"400W","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMA","Voltage - Breakdown (Min)":"8.33V","Voltage - Clamping (Max) @ Ipp":"12.9V","Voltage - Reverse Standoff (Typ)":"7.5V","Current - Peak Pulse (10/1000µs)":"31A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1092","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/34f8b69d3d41ce3a7e5d6d3f2b7ec8e2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Diodes Incorporated provide for SMAJ7.5CAQ-13-F?","answer":"Diodes Incorporated typically provides RoHS and REACH compliance declarations for this part.
