The DO-214AA (SMB) surface-mount package suits automated assembly for general-purpose protection on power, signal, or data lines where the circuit sees symmetrical clamping needs. ## 24 V rail protection — the clamping window matters A 24 V reverse standoff voltage means this part conducts negligible leakage below that level; the rail sits safely under the standoff during normal operation. The 26.7 V minimum breakdown ensures the device starts clamping before the protected circuitry sees damage, while the 38.9 V clamp at 16 A limits the let-through voltage during a surge event. For a 24 V DC bus or a 24 VAC signal line, these three numbers define the protection corridor the designer budgets against. ## Bidirectional — one device for symmetrical clamping This eliminates the need for two unidirectional diodes back-to-back on AC signal lines or on DC rails where reverse-polarity events are possible. The part is marked as having no power line protection (it is not designed for sustained overvoltage or continuous fault conditions), so it fits best on auxiliary power inputs, I/O lines, or communication ports where the threat is a transient spike, not a sustained rail fault. This gives design engineers and procurement teams confidence for new BOM entries and ongoing production builds.","metaTitle":"STMicroelectronics SMBJ24CA-TR TVS Diode, 600W Bidirectional","metaDescription":"STMicroelectronics SMBJ24CA-TR bidirectional TVS diode, 600W peak pulse power, 24V standoff, 38.9V clamp.

Both share the same 24 V standoff voltage, 600 W peak pulse power, and DO-214AA package. The 'C' in the order code indicates bidirectional clamping; the 'A' variant clamps only one polarity. Choose the CA for AC signal lines or DC rails where reverse-polarity transients are possible, and the A for unipolar DC rails where only positive clamping is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SMBJ24CA-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SMBJ24CA-TR when reusing this data.
