The 600W figure is the product of clamp voltage and peak current at the specified pulse shape; for shorter pulses the peak power capability is higher per the TVS derating curve. ## Package and board integration The SMB package body is larger than the SMA variant, offering better thermal dissipation for the 600W pulse rating — the copper pad area on the PCB under the cathode tab directly influences the junction-to-ambient thermal resistance during the surge. The part is rated for General Purpose applications, meaning it is not qualified to AEC-Q101 automotive stress standards. For designs requiring automotive-grade TVS, the AEC-Q101 version of the same die in the same package carries a different ordering suffix.","metaTitle":"SMBJ30A-13-F Diodes Inc TVS, 30V Standoff, 600W, DO-214AA","metaDescription":"SMBJ30A-13-F Zener TVS diode, 30V reverse standoff, 48.4V clamp, 600W peak pulse, DO-214AA (SMB).

The difference is packaging: -13-F denotes a specific tape-and-reel reel size and lead-free finish. For a BOM that already specifies the -13-F suffix, confirm the reel quantity and finish requirement before substituting the base part number."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMBJ30A-13-F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMBJ30A-13-F when reusing this data.
