That 133 V to 193 V clamping window absorbs the surge energy before it reaches the protected load. Housed in the standard DO-214AC (SMA) surface-mount package, the SMAJ120CA-13 occupies a compact footprint suitable for high-density PCB layouts. The SMA supplier device package designation matches the industry-standard SMA outline, so the land pattern and solder stencil aperture are well-documented across assembly houses. The wide thermal margin means derating for ambient heat is straightforward — the 400 W rating holds at 25°C and derates linearly above that. The base product number SMAJ120 covers both unidirectional and bidirectional variants; the CA suffix specifically denotes the bidirectional configuration. When ordering, confirm the exact ordering code SMAJ120CA-13 to ensure the bidirectional channel and Tape & Reel packaging.","metaTitle":"SMAJ120CA-13 Diodes Inc TVS, 400W, 120V Bidirectional, SMA","metaDescription":"Active-production SMAJ120CA-13 bidirectional TVS diode, 400W peak pulse, 120V standoff, 193V clamp.
