It targets applications requiring a low forward voltage drop — 600 mV typical at 1 A — and a high junction temperature ceiling of 175 °C, making it a fit for power supplies, DC-DC converters, and reverse-polarity protection in industrial and automotive-adjacent environments. ## What the 175 °C junction rating buys you The 175 °C maximum junction temperature places this part above the standard 150 °C Schottky tier. That headroom matters when the diode sits near a hot inductor or in a sealed enclosure with limited airflow — the thermal margin reduces the need for oversized copper pads or forced cooling. At 120 V reverse and 1.9 A average forward current, the part handles 48 V bus rails with derating to spare. The 250 µA reverse leakage at 120 V is typical for a 120 V Schottky at 25 °C; expect it to rise with temperature, so budget for increased dissipation if the ambient runs above 85 °C. ## Package and footprint — SlimSMAW vs standard SMA The SlimSMAW (DO-221AD) package is a flat-lead, low-profile variant of the SMA family. It shares the same 2.6 mm body width as a standard SMA but sits lower on the board — roughly 0.85 mm tall versus 2.0 mm for a typical SMA. Mounting is surface-mount per the DO-221AC / SMA Flat Leads case outline.","metaTitle":"VSS8D2M12-M3/I Schottky Diode, 120V 1.9A, SlimSMAW, Active","metaDescription":"VSS8D2M12-M3/I Schottky rectifier, 120V reverse, 1.9A average, 600mV Vf at 1A, 175°C Tj, SlimSMAW package, ROHS3 compliant, active production.","metaKeywords":null},"attributes":{"series":"eSMP®, TMBS®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"eSMP®, TMBS®","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"DO-221AC, SMA Flat Leads","lifecycle_stage":"eol_hot","Capacitance @ Vr, F":"220pF @ 4V, 1MHz","Supplier Device Package":"SlimSMAW (DO-221AD)","Current - Reverse Leakage @ Vr":"250 µA @ 120 V","Voltage - DC Reverse (Vr) (Max)":"120 V","Current - Average Rectified (Io)":"1.9A","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"600 mV @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.42000","currency":"USD"},{"qty":10,"price":"$0.34400","currency":"USD"},{"qty":100,"price":"$0.23440","currency":"USD"},{"qty":500,"price":"$0.17580","currency":"USD"},{"qty":1000,"price":"$0.13184","currency":"USD"},{"qty":3500,"price":"$0.12086","currency":"USD"},{"qty":7000,"price":"$0.11401","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/17490109366db8b58fa02e0c1c909e7f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the specifications of VSS8D2M12-M3/I?","answer":"It comes in a SlimSMAW (DO-221AD) surface-mount package."},{"question":"Is VSS8D2M12-M3/I RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/VSS8D2M12-M3-I","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/VSS8D2M12-M3-I when reusing this data.
