For AC mains or high-energy surge paths, a separate MOV or gas-discharge tube is needed upstream.","metaTitle":"SMBJ18CAE3/TR13 TVS Diode – 18V Bidirectional, 600W","metaDescription":"SMBJ18CAE3/TR13 bidirectional Zener TVS from Microchip Technology. 18V reverse standoff, 29.2V clamp, 600W peak pulse.

No stock-holding claim is made here; availability is confirmed per order."},{"question":"What is the closest pin-compatible alternative to SMBJ18CAE3/TR13 in this Circuit Protection family?","answer":"The SMBJ18CA (without the suffix) is a common cross-shop candidate. Both are bidirectional Zener TVS diodes in DO-214AA with the same 18V reverse standoff and 600W peak pulse rating. The suffix on this part indicates Microchip's standard lead-free finish – confirm the RoHS status of the alternative against your BOM requirements before substituting."},{"question":"Is SMBJ18CAE3/TR13 RoHS compliant?","answer":"The evidence does not explicitly list RoHS compliance status. The suffix on Microchip parts typically denotes lead-free / RoHS-compliant finish, but verify against the latest manufacturer documentation or request a certificate of compliance with your order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMBJ18CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMBJ18CAE3-TR13 when reusing this data.
