When a surge hits, breakdown starts at 111V minimum and the diode clamps the voltage to 179V maximum at the peak pulse current of 2.8A (10/1000µs waveform). The 500W peak pulse power rating tells you it can absorb a decent transient without failing — useful for protecting sensitive downstream circuitry in general-purpose industrial or telecom gear. ## Package and mounting — DO-214AC (SMA) surface-mount This part comes in the DO-214AC (SMA) package, a common surface-mount footprint for TVS diodes. It's supplied on Tape & Reel (TR), which means it's ready for automated pick-and-place and reflow soldering. No power line protection feature — this is a straight transient clamp, not a crowbar or a filter. Microchip lists the SMAJ100E3/TR13 as Active product status.","metaTitle":"SMAJ100E3/TR13 – Microchip Zener TVS Diode, 100V, 500W","metaDescription":"SMAJ100E3/TR13 from Microchip Technology – Zener TVS diode, 100V reverse standoff, 500W peak pulse power, DO-214AC (SMA) package.

The primary difference is the package variant: SMAJ100E3/TR13 is the tape-and-reel (TR) option for automated assembly, while SMAJ100A typically comes in bulk or different packaging. Functionally they are interchangeable for the same clamping job, but confirm the package code matches your assembly line's feeder requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ100E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ100E3-TR13 when reusing this data.
