The bidirectional channel means one device protects against both positive and negative surges — useful on AC signal lines or DC rails where reverse polarity is a risk. ## Active lifecycle — no EOL risk for current BOMs This is a standard-production part in the 1.5SMC series, widely used across general-purpose circuit protection applications.","metaTitle":"1.5SMC18CA Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5SMC18CA bidirectional TVS diode, 1500W peak pulse power, 15.3V standoff, 25.2V clamp.
