For existing BOM lines, this part is available through independent surplus and broker channels; quantities and pricing are confirmed at RFQ, not held as standing inventory. ## 28V rail clamp — 400W peak pulse That 400W peak pulse power rating means the device can absorb a single transient of that energy without failing — useful for clamping inductive kickback or ESD events on a 24V nominal bus where the steady-state rail stays under 28V. ## DO-214AC SMA — surface-mount placement Housed in the DO-214AC (SMA) package, a standard surface-mount footprint. The operating junction temperature range is -55°C to 150°C, covering industrial and automotive ambient conditions.","metaTitle":"SMAJ28A-13 Diodes Inc TVS Zener, 28V, 400W, DO-214AC","metaDescription":"SMAJ28A-13 Diodes Inc unidirectional TVS diode, 28V reverse standoff, 400W peak pulse.

The base product number is SMAJ28, and the package is the standard DO-214AC SMA footprint. Any functional replacement would need to match the 28V reverse standoff, unidirectional polarity, and 400W peak pulse rating in the same package — but no official cross-reference is published."},{"question":"What compliance documentation does Diodes Incorporated provide for SMAJ28A-13?","answer":"No specific RoHS, REACH, UL, or IEC compliance statements are recorded in this listing. Standard Diodes Incorporated TVS diodes in the SMAJ series are typically RoHS-compliant and halogen-free, but the buyer should verify the specific manufacturing date code and lot at RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMAJ28A-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/SMAJ28A-13 when reusing this data.
