The -40°C to 175°C junction range covers under-hood and engine-bay environments where ambient temperatures exceed 125°C. The Schottky barrier construction with fast recovery speed (<500ns, >200mA Io) means the diode's reverse-recovery charge is negligible — the dominant switching loss is the forward conduction loss, not the recovery tail. This keeps the ringing and EMI signature low in high-frequency DC-DC converters and OR-ing circuits. ## Forward drop, leakage, and the thermal budget At 7.5 A forward current the typical forward drop is 830 mV — this sets the conduction loss floor. The 600 µA reverse leakage at 120 V rated reverse voltage is a check point for standby power budgets; leakage doubles with every 10°C rise above 25°C, so at 125°C junction the leakage current can dominate the off-state loss. Each diode in the common-cathode pair is rated for 4.2 A average rectified current. In a typical 15 A total output application (the '15A' in the description), the two diodes share the load, but the thermal coupling inside the FlatPAK package means the junction temperature of the hotter diode limits the total throughput. ## FlatPAK 5x6 — board integration and thermal spreading The 8-PowerTDFN package, marketed as FlatPAK (5x6), is a low-inductance surface-mount package with a large exposed pad on the bottom.","metaTitle":"Vishay V15KM120C-M3/H Schottky Diode, 120V, 4.2A, AEC-Q101","metaDescription":"Vishay V15KM120C-M3/H Schottky diode, 120V reverse, 4.2A average per diode, 830mV Vf, AEC-Q101 qualified, FlatPAK 5x6 package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"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":"8-PowerTDFN","lifecycle_stage":"eol_hot","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"FlatPAK (5x6)","Current - Reverse Leakage @ Vr":"600 µA @ 120 V","Voltage - DC Reverse (Vr) (Max)":"120 V","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"830 mV @ 7.5 A","Current - Average Rectified (Io) (per Diode)":"4.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.91","priceTiers":[{"qty":1,"price":"$0.91000","currency":"USD"},{"qty":10,"price":"$0.81200","currency":"USD"},{"qty":100,"price":"$0.63290","currency":"USD"},{"qty":500,"price":"$0.52284","currency":"USD"},{"qty":1500,"price":"$0.42834","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/78b4ac1117906b6c815ce816aea67872.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/V15KM120C-M3%2FH/alternatives.json"},"ai":{"faq":[{"question":"What automotive qualification does the V15KM120C-M3/H carry?","answer":"The V15KM120C-M3/H is AEC-Q101 qualified, the automotive discrete semiconductor reliability standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/V15KM120C-M3-H","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/V15KM120C-M3-H when reusing this data.
