The strip packaging variant is the reel-taped option; confirm the orientation stripe matches the cathode marking on the board before reflow.","metaTitle":"Diotec 1.5SMCJ40A-AQ TVS Diode, 40V Standoff, 1.5kW","metaDescription":"Diotec 1.5SMCJ40A-AQ unidirectional TVS diode, 40V reverse standoff, 1.5kW peak pulse, 64.5V clamping at 23.3A.

The TVS absorbs the transient energy and clamps the voltage at a level the protected IC can survive, returning to its high-impedance state once the event passes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ40A-AQ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ40A-AQ when reusing this data.
