Each diode is rated for 45 V reverse voltage and delivers 15 A average rectified current at a forward voltage of 570 mV maximum. That 570 mV at 15 A sets the conduction loss per leg — at full load each diode dissipates roughly 8.6 W, so the thermal path through the D²PAK tab to the PCB copper plane is the design variable that determines real-world current capability. ## AEC-Q101 gate: under-hood and chassis-domain ready This part carries AEC-Q101 qualification, placing it in the automotive-grade tier for discrete semiconductors. The 200 °C maximum junction temperature rating gives additional thermal headroom over standard 150 °C Schottky parts, which matters when the diode shares a heatsink with a switching FET or sits in a high-ambient engine-bay environment. ## Common-cathode pair: the topology that saves board space The two diodes share a common cathode (pin 2 and tab), with independent anodes on pins 1 and 3. This is the standard pinout for center-tap full-wave rectification and for OR-ing diodes in redundant power feeds — one package replaces two discrete SMD Schottkys, cutting placement cost and board area.","metaTitle":"STPS3045CGY-TR Schottky Diode, 45V 15A, AEC-Q101, D2PAK","metaDescription":"STPS3045CGY-TR automotive Schottky rectifier: 45V, 15A per diode, 570mV Vf, 200°C Tj max, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":null,"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-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS3045","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D²PAK","Current - Reverse Leakage @ Vr":"200 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Operating Temperature - Junction":"200°C(Max)","Voltage - Forward (Vf) (Max) @ If":"570 mV @ 15 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5300","priceTiers":[{"qty":1,"price":"$1.53000","currency":"USD"},{"qty":10,"price":"$1.27500","currency":"USD"},{"qty":100,"price":"$1.01450","currency":"USD"},{"qty":500,"price":"$0.85842","currency":"USD"},{"qty":1000,"price":"$0.72835","currency":"USD"},{"qty":2000,"price":"$0.69194","currency":"USD"},{"qty":5000,"price":"$0.66592","currency":"USD"},{"qty":10000,"price":"$0.64388","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/48fcc3d15501a083daface8769706844.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS3045CGY-TR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS3045CGY-TR automotive qualified?","answer":"Yes, it is listed under the Automotive series and carries AEC-Q101 qualification, making it suitable for automotive applications including under-hood and chassis-domain electronics."},{"question":"What is the closest pin-compatible alternative to STPS3045CGY-TR?","answer":"For dual-sourcing, evaluate other AEC-Q101 45 V common-cathode Schottky pairs in D²PAK from major manufacturers, but confirm pinout and thermal performance against the STPS3045CGY-TR datasheet before committing the BOM."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS3045CGY-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS3045CGY-TR when reusing this data.
