The fast recovery time (≤500 ns) and low forward drop (900 mV at 10 A) suit it for high-frequency switching power supplies, freewheeling diodes, and polarity protection in telecom and industrial DC-DC converters. The 170 V reverse voltage rating provides margin for 48 V and 72 V bus rails, and covers the reflected voltage in flyback converters with up to 100 V input. The 10 A per diode average current handles output rectification in the 100–200 W range. The 900 mV forward drop at 10 A is typical for a 170 V Schottky — expect higher conduction loss than a lower-voltage part, but the fast recovery (≤500 ns) keeps switching losses low in continuous-conduction-mode designs. The 15 µA reverse leakage at 170 V is a room-temperature spec; at 125 °C junction it will rise significantly, so thermal derating of the forward current is necessary above 100 °C. The D2PAK (TO-263-3) surface-mount package has a large exposed tab for thermal dissipation. The common-cathode pair shares the tab as the cathode connection, so the tab is not electrically neutral — the PCB copper plane must be either isolated or connected to the cathode rail. The 2-lead-plus-tab footprint is standard for D2PAK; the tab is the primary heat path, so a via array under the tab is recommended for thermal transfer to inner layers.","metaTitle":"STPS20170CG Schottky Diode, 170 V, 10 A, Common Cathode","metaDescription":"STPS20170CG Schottky diode pair, 170 V, 10 A per diode, fast recovery ≤500 ns, common cathode in 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":"STPS20170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Current - Reverse Leakage @ Vr":"15 µA @ 170 V","Voltage - DC Reverse (Vr) (Max)":"170 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"900 mV @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d27139a2255bf6596b7cdcb82b3b59c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20170CG/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20170CG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20170CG when reusing this data.
