The unidirectional configuration clamps positive transients relative to ground; for bidirectional protection on AC-coupled lines, a series pair or a bidirectional variant is needed.","metaTitle":"Littelfuse 1.5KE320A Zener TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE320A Zener TVS diode, 1500W peak pulse power, 273V reverse standoff, 441V clamping.
