Power line protection is not built in — this is a general-purpose transient suppressor, not a mains-rated MOV — but for DC rails and signal lines it provides clean, fast clamping.","metaTitle":"1.5KE18C-B Littelfuse TVS Diode, 1.5kW, Bidirectional","metaDescription":"1.5KE18C-B Littelfuse Zener TVS diode, 1500W peak pulse power, 15.3V standoff, 26.46V clamp.
