That 53.3V ceiling is what the downstream silicon sees — if your 33V regulator's abs-max is 60V, this TVS keeps the transient inside the safe zone. Rated at 400W peak pulse power for the 10/1000µs pulse shape — enough for moderate ESD and surge events on a control board or sensor interface, but not sized for direct lightning surge on an outdoor cable. The DO-214AC (SMA) body handles the thermal pulse without cracking the solder joint. ## Package and reflow fit Surface-mount DO-214AC (SMA) package, supplied on Tape & Reel (TR) or Cut Tape (CT) — the reel option feeds directly into a pick-and-place machine with no carrier changeover. The SMA footprint is standard across Diodes Inc and many second-source TVS families, so the PCB land pattern stays the same if you swap brands. The 150°C TJ max means the TVS can sit near a hot regulator or motor driver without derating the clamping performance. Listed as Active by Diodes Incorporated — no end-of-life notice, no last-time-buy window. The base product number SMAJ33 covers both unidirectional and bidirectional variants; the CA suffix identifies the bidirectional version. Sourced through independent distribution channels. No minimum order restriction; Tape & Reel quantities typical for the package.","metaTitle":"SMAJ33CA-13 Diodes Inc TVS, 33V Bidirectional, DO-214AC","metaDescription":"SMAJ33CA-13 bidirectional TVS diode, 33V reverse standoff, 53.3V clamp, 400W peak pulse, DO-214AC SMA.
