The bidirectional configuration (one channel) protects against both positive and negative transients on a single line, simplifying the BOM for AC-coupled or bipolar signal buses.","metaTitle":"SMCJ12CAE3/TR13 TVS Diode – 1.5 kW, 12 V, DO-214AB","metaDescription":"SMCJ12CAE3/TR13 Zener TVS, 1500 W peak pulse, 12 V reverse standoff, 19.9 V clamping.
