Use it on DC power buses, signal lines, and low-voltage AC circuits where the standoff and clamping levels match the rail.","metaTitle":"Littelfuse 1.5KE9.1CA TVS Diode, 1500W, 7.78V Standoff","metaDescription":"Littelfuse 1.5KE9.1CA bidirectional Zener TVS diode, 1500W peak pulse power, 7.78V standoff, DO-201 package.
