Its 18.9V minimum breakdown voltage and 27.6V maximum clamping at 18.1A peak pulse define the protection window: the rail must tolerate the clamp voltage without damage, and the upstream supply must not exceed the standoff during normal operation. ## 500W surge capability in a small SMA footprint The DO-214AC (SMA) body keeps the PCB footprint small — roughly 4.5 mm × 2.8 mm — but the copper pad area under the cathode tab sets the thermal impedance; a solid ground-plane connection improves heat sinking during repetitive surges. The suffix in the base part number (SMAJ17AE3) denotes RoHS compliance and tin-lead plating compatibility — verify your assembly process requirements against the specific plating option.","metaTitle":"SMAJ17AE3/TR13 Zener TVS Diode – Microchip, 500W, DO-214AC","metaDescription":"SMAJ17AE3/TR13 from Microchip: Zener TVS, 500W peak pulse, 17V standoff, 18.9V breakdown, 27.6V clamp, DO-214AC.
