The junction is rated from -40°C to 175°C, so the design must budget the self-heating against the ambient temperature in the enclosure; at 85°C ambient, the remaining 90°C rise allows roughly 1.5 A continuous before derating begins. Reverse leakage is 35 µA at 40 V, which becomes the dominant thermal contributor above 125°C junction — the leakage doubles roughly every 10°C, and at 175°C the leakage current can exceed the forward conduction loss in a lightly loaded rail. ## Recovery speed and switching profile Listed as a fast-recovery type with trr ≤ 500 ns at forward current above 200 mA. This recovery speed suits 50–400 kHz DC-DC converters where the Schottky's low reverse-recovery charge avoids the ringing and switching loss a PN diode would incur. At higher frequencies the junction capacitance becomes the limiting factor; the SOD-123F package keeps parasitic inductance low enough for clean commutation.","metaTitle":"STPS2L40ZFY Schottky Diode 40V 2A SOD-123F AEC-Q101","metaDescription":"STPS2L40ZFY automotive Schottky rectifier, 40V 2A, 630mV Vf at 2A, -40°C to 175°C junction, SOD-123F, AEC-Q101.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"SOD-123F","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS2L40","Capacitance @ Vr, F":"-","Supplier Device Package":"SOD-123F","Current - Reverse Leakage @ Vr":"35 µA @ 40 V","Voltage - DC Reverse (Vr) (Max)":"40 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"630 mV @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4700","priceTiers":[{"qty":1,"price":"$0.47000","currency":"USD"},{"qty":10,"price":"$0.33500","currency":"USD"},{"qty":100,"price":"$0.16870","currency":"USD"},{"qty":500,"price":"$0.14952","currency":"USD"},{"qty":1000,"price":"$0.11635","currency":"USD"},{"qty":3000,"price":"$0.10414","currency":"USD"},{"qty":6000,"price":"$0.10181","currency":"USD"},{"qty":9000,"price":"$0.09017","currency":"USD"},{"qty":30000,"price":"$0.08901","currency":"USD"},{"qty":75000,"price":"$0.07563","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3a7b562e6b450510fc66e67814f0735d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS2L40ZFY/alternatives.json"},"ai":{"faq":[{"question":"Is STPS2L40ZFY AEC-Q101 qualified?","answer":"Yes, the part is AEC-Q101 qualified and carries an automotive grade classification, suitable for stress-tested automotive applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS2L40ZFY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS2L40ZFY when reusing this data.
