The 243V clamping voltage is the maximum the protected load sees during the event; if the downstream circuitry has a 250V abs-max rating, this TVS provides margin. The DO-214AC (SMA) package is a standard surface-mount footprint — the same pad pattern used across the SMAJ family, so a BOM swap between voltage variants needs no layout change. ## Lifecycle and procurement Listed as Active — Diodes Incorporated continues to manufacture this part with no announced end-of-life. The SMAJ150A-13-F ships in Tape & Reel (TR) or Cut Tape (CT), standard for automated pick-and-place assembly.","metaTitle":"SMAJ150A-13-F TVS Diode, 400W, 150V Standoff, DO-214AC","metaDescription":"Diodes Inc SMAJ150A-13-F Zener TVS, 400W peak pulse, 150V reverse standoff, 243V clamp, DO-214AC SMA.
