The 33.3 V reverse standoff voltage sets the maximum continuous DC or peak AC voltage the protected line can carry without the TVS conducting leakage current.","metaTitle":"1.5SMC39C Littelfuse TVS, 1500W, Bidirectional, DO-214AB","metaDescription":"1.5SMC39C Littelfuse 1500W bidirectional TVS diode, 33.3V standoff, 56.6V clamp, DO-214AB.

The 1.5SMC series shares the same DO-214AB footprint, so a different voltage rating within the same series (e.g., 1.5SMC36C or 1.5SMC43C) will fit the same PCB land pattern but shifts the clamping threshold. A full parametric cross-reference against the original design's rail voltage and transient energy is recommended before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5SMC39C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5SMC39C when reusing this data.
