The body is small enough that the pad layout doesn't trap heat under the part — lift the part, not the pad. Bidirectional means you don't worry about polarity; one part covers both positive and negative transients on a bipolar line or an AC-coupled signal. ## Active production and sourcing posture The base product number is SMAJ48, so the -13 suffix indicates tape-and-reel packaging.","metaTitle":"SMAJ48CA-13 Diodes Inc TVS, 48V Bidirectional, DO-214AC","metaDescription":"SMAJ48CA-13 bidirectional TVS diode, 48V reverse standoff, 77.4V clamp, 400W peak pulse.
