At the 2.7A peak pulse current (IPP), the clamp voltage hits 146V maximum — this is the voltage the protected IC sees during a surge. For a 90V-rated MOSFET or DC-DC converter with a 150V abs-max rating, the 146V clamp leaves 4V of headroom; a tighter 120V-rated part would need a lower-voltage TVS or a series resistor to split the surge energy. ## DO-214AC SMA — field-swappable with a standard iron The DO-214AC (SMA) footprint is one of the most common TVS packages — the same land pattern serves the whole SMAJ series from 5V to 188V standoff. A standard soldering iron and tweezers are enough to swap it on a populated board; no hot-air station needed. Surface-mount assembly with Tape & Reel packaging means it feeds straight into a pick-and-place line. The SMA body is large enough that the polarity band (cathode) is readable under a magnifying lamp — orientation mistakes are rare even in rework. Because the SMAJ series covers a wide voltage range on the same die and package platform, Diodes is unlikely to phase out individual voltage variants — the mask set and assembly tooling are shared across the whole family.","metaTitle":"SMAJ90A-13-F Diodes Inc TVS, 90V Standoff, DO-214AC","metaDescription":"Diodes Inc SMAJ90A-13-F Zener TVS, 400W peak pulse, 90V reverse standoff, 146V clamp, DO-214AC SMA.
