The bidirectional configuration means a single device protects both polarities — useful on AC-coupled or floating lines where the transient can swing either direction.","metaTitle":"SMAJ54CAE3/TR13 – Microchip 54V Bidirectional TVS Diode","metaDescription":"SMAJ54CAE3/TR13 Zener TVS diode, 54V reverse standoff, 87.1V clamp, 500W peak pulse, DO-214AC.

The 54V reverse standoff voltage is the standard choice for a 48V nominal rail — the TVS remains non-conducting under normal conditions and clamps transients before they exceed the downstream component ratings. The 87.1V clamp at 5.7A peak pulse current provides a safe margin for most 48V DC-DC converters and downstream ICs rated to 60-80V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ54CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ54CAE3-TR13 when reusing this data.
