The 630 mV typical forward drop at 3 A keeps conduction losses manageable in a compact DPAK footprint. ## 40 V blocking, 3 A per leg — thermal and electrical headroom Each of the two Schottky diodes in the common-cathode pair handles 3 A continuous (average rectified). The 40 V reverse voltage rating provides margin for 12 V automotive systems where load-dump transients can push the bus above 30 V.","metaTitle":"STPS640CBY-TR Schottky Diode Array, 40V 3A, DPAK, AEC-Q101","metaDescription":"STPS640CBY-TR: Automotive Schottky diode array, 40V 3A per diode, fast recovery ≤500ns, DPAK, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS640","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"DPAK","Current - Reverse Leakage @ Vr":"100 µA @ 40 V","Voltage - DC Reverse (Vr) (Max)":"40 V","Operating Temperature - Junction":"-40°C~150°C","Voltage - Forward (Vf) (Max) @ If":"630 mV @ 3 A","Current - Average Rectified (Io) (per Diode)":"3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8900","priceTiers":[{"qty":1,"price":"$0.89000","currency":"USD"},{"qty":10,"price":"$0.79400","currency":"USD"},{"qty":100,"price":"$0.61920","currency":"USD"},{"qty":500,"price":"$0.51150","currency":"USD"},{"qty":1000,"price":"$0.44030","currency":"USD"},{"qty":2500,"price":"$0.44030","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/261262105c66c4aa06c1c15cb1841adf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS640CBY-TR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS640CBY-TR RoHS compliant?","answer":"Yes, the STPS640CBY-TR is ROHS3 compliant, meeting the current EU directive for restriction of hazardous substances."},{"question":"What is the footprint of STPS640CBY-TR?","answer":"The STPS640CBY-TR is supplied in a TO-252-3 (DPak) surface-mount package with 2 leads plus a tab."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS640CBY-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS640CBY-TR when reusing this data.
