The 400 W peak pulse power rating tells you the energy-handling capacity at that pulse shape — a higher standoff voltage means lower peak current for the same power rating, so this 33 V part handles less surge current than a lower-voltage SMAJ part. ## DO-214AC (SMA) footprint and board integration The diode comes in the DO-214AC (SMA) surface-mount package, with the supplier device package designated as SMA. The footprint is standard for this package class — the cathode is marked by a band on the body, and the small outline suits automated pick-and-place assembly. The wide range means the clamping performance is specified across the full temperature band, not just at 25°C — leakage current will increase at the hot end, but the avalanche breakdown voltage shifts predictably. ## Active production and sourcing posture Sourced through independent distribution channels.","metaTitle":"SMAJ33A-13-F Diodes Inc TVS Diode, 400W, DO-214AC","metaDescription":"SMAJ33A-13-F Zener TVS diode from Diodes Inc, 400W peak pulse power, 33V standoff, DO-214AC (SMA) package.
