Peak pulse power is rated at 400W — adequate for suppressing transients on 24V DC supplies, sensor lines, or I/O rails in industrial control panels where the energy content of a typical surge stays below that limit. ## Package and board-fit — DO-214AC (SMA) Supplied in a DO-214AC (SMA) surface-mount package, the SMAJ28CA-13 is intended for reflow assembly on standard FR-4 boards. The operating junction temperature range spans -55°C to +150°C, which covers both commercial and extended industrial environments without derating concerns.","metaTitle":"SMAJ28CA-13 Diodes Inc TVS, 28V Bidirectional, 400W","metaDescription":"SMAJ28CA-13 bidirectional TVS diode, 28V reverse standoff, 45.4V clamp, 400W peak pulse.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"400W","Base Product Number":"SMAJ28","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMA","Voltage - Breakdown (Min)":"31.1V","Voltage - Clamping (Max) @ Ipp":"45.4V","Voltage - Reverse Standoff (Typ)":"28V","Current - Peak Pulse (10/1000µs)":"8.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a6e414533ed6f0f7c15ae6d19d66ae3c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMAJ28CA-13/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to SMAJ28CA-13?","answer":"No official successor or pin-compatible cross-reference is recorded from Diodes Incorporated.
