Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE18CA is a through-hole part suited for wave-solder or hand-solder assembly. The DO-201 body handles the thermal pulse of a 1500 W surge without derating at 25 °C ambient. The wide range means the clamping behaviour stays consistent across the full temperature envelope.","metaTitle":"1.5KE18CA Littelfuse TVS Diode, 1500W, 15.3V Standoff","metaDescription":"Littelfuse 1.5KE18CA bidirectional TVS, 1500W peak pulse, 15.3V standoff, 25.2V clamp.
