The forward voltage drop is 570 mV at 15 A per diode — a key figure for efficiency in OR-ing, freewheeling, and output rectification stages where lower Vf reduces conduction loss. The fast recovery characteristic (≤ 500 ns, > 200 mA) is typical for a Schottky; the real switching advantage is the lack of stored charge, so recovery losses are minimal in high-frequency PFC and flyback converters. ## D2PAK footprint — reflow and thermal handling","metaTitle":"STPS3045CG Schottky Rectifier, 45V 30A Dual Common Cathode","metaDescription":"STPS3045CG dual Schottky rectifier, 45 V, 30 A total, 570 mV Vf at 15 A, D2PAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","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":"$1.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2c9bd8aea83ec028bac6e660e8b4f4ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS3045CG/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS3045CG?","answer":"No official replacement order code is recorded.
