The 64.6 V minimum breakdown voltage gives a 6.5 V guard band above the 58.1 V standoff rating, ensuring the diode does not conduct at normal operating voltage while triggering reliably above the threshold. Single unidirectional channel, so it protects one DC rail polarity per device. ## Temperature range and package fit The DO-201AA / DO-27 axial leaded package suits through-hole boards where the lead bend and body length fit standard 0.4-inch pitch layouts. No power line protection (not designed for AC mains clamping), so it is best applied on DC power buses, signal lines, or low-voltage secondary rails where a unidirectional clamp is needed.","metaTitle":"Littelfuse 1.5KE68A-TB TVS Diode, 1.5kW, 92V Clamp","metaDescription":"Littelfuse 1.5KE68A-TB Zener TVS diode, 1500W peak pulse, 92V clamping, DO-201 package.
