The DO-214AC (SMA) package suits reflow assembly and keeps the footprint small for dense PCB layouts. ## Breakdown and clamping margins Minimum breakdown voltage is 15.6V, giving a guard band above the 14V reverse standoff. The 23.2V clamp at 21.5A Ipp means the protected circuit sees less than 24V during a surge — a typical margin for 16V-rated downstream components. Unidirectional, single-channel configuration simplifies routing on a single supply rail.","metaTitle":"SMAJ14AE3/TR13 Zener TVS Diode – 500W, 14V, DO-214AC","metaDescription":"SMAJ14AE3/TR13 from Microchip: Zener TVS, 500W peak pulse, 14V reverse standoff, DO-214AC.

Electrically the two are identical — same 14V standoff, same 500W peak pulse rating, same DO-214AC package. If your BOM calls out SMAJ14A, the variant drops in as a direct replacement with no change in clamping performance."},{"question":"What does the suffix in SMAJ14AE3 mean?","answer":"The suffix designates a lead-free / RoHS-compliant termination finish.
