No power line protection feature — this is a signal or low-power rail clamp, not a mains surge protector.","metaTitle":"SMBJ28CE3/TR13 – Microchip 28V Zener TVS, 600W, DO-214AA","metaDescription":"SMBJ28CE3/TR13 Microchip Zener TVS diode: 28V reverse standoff, 600W peak pulse, bidirectional, DO-214AA SMB.

A unidirectional part clamps only one polarity — substituting it would leave the opposite polarity transient unprotected unless you add a second device. Check the polarity requirement of your circuit before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMBJ28CE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMBJ28CE3-TR13 when reusing this data.
