That means a 26V rail sees the TVS clamp at under 47V during a surge — well within the typical 60V absolute maximum of downstream 24V-to-5V regulators. The 28.9V minimum breakdown gives a ~2.9V guard band above the 26V standoff, so normal line ripple won't trigger false clamping. Microchip lists the SMAJ26E3/TR13 as Active. ## Package and reel format for the pick-and-place line Supplied in Tape & Reel (TR), the DO-214AC (SMA) package is a standard JEDEC outline for surface-mount TVS diodes.","metaTitle":"SMAJ26E3/TR13 Zener TVS Diode – 26V, 500W, DO-214AC","metaDescription":"SMAJ26E3/TR13 Zener TVS diode, 26V reverse standoff, 500W peak pulse power, DO-214AC (SMA) surface mount.

The SMAJ26E3/TR13 is a Microchip part; the P4SMAJ26A is typically a Littelfuse or Vishay offering. Verify the clamping voltage and peak pulse current against your surge requirement before substituting — the datasheet values may differ slightly between manufacturers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ26E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ26E3-TR13 when reusing this data.
