Rated for 400 W peak pulse power, this part handles surges typical of industrial control and general-purpose DC supplies. The bidirectional configuration (one channel) suits AC signal lines or bipolar DC buses where polarity is not fixed. ## Package and rework — DO-214AC SMA Supplied in Tape & Reel (TR) or Cut Tape (CT) options, it feeds directly into pick-and-place for volume assembly. The -13 suffix indicates the reel packaging variant. Operating from -55 °C to 150 °C junction temperature, this TVS diode covers the full industrial temperature envelope. It is suitable for outdoor telecom cabinets, motor drive DC buses, and automotive-adjacent environments where the ambient sees -40 °C and the self-heating from repetitive surges pushes the junction toward the upper end.","metaTitle":"Diodes Inc SMAJ15CA-13 TVS Diode, 15V, 400W, DO-214AC","metaDescription":"Bidirectional Zener TVS diode, 15V reverse standoff, 24.4V clamp, 400W peak pulse.

The unidirectional version (SMAJ15A-13) is the closest alternative where polarity is fixed. Both share the same 400 W peak pulse rating, 15 V standoff, and DO-214AC package, differing only in the number of protection channels (bidirectional vs unidirectional)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMAJ15CA-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/SMAJ15CA-13 when reusing this data.
