The single bidirectional channel protects against both positive and negative transients on a single line, reducing component count on bidirectional buses.","metaTitle":"SMAJ40CE3/TR13 TVS Diode – 40V, 500W, DO-214AC, Active","metaDescription":"Microchip SMAJ40CE3/TR13 Zener TVS diode, 40V reverse standoff, 500W peak pulse, DO-214AC SMA package.
