The 20 µA reverse leakage at 170 V is a datasheet maximum; leakage climbs with junction temperature, so at the 175°C max Tj it will be significantly higher. This part is built for the output stage of a high-voltage power supply, OR-ing diodes in a redundant 48 V or 72 V telecom rectifier, or reverse-polarity protection on a 100 V+ bus where a standard 100 V Schottky would be too marginal. Any stock in the channel is new-old-stock or surplus from franchised distribution that has aged out of the manufacturer's order window. ## D2PAK common-cathode — footprint and thermal note The STPS30170CG lives in a D2PAK (TO-263-3) surface-mount package with an exposed tab that carries the common cathode. The tab is the main thermal path — PCB copper area and via stitching under the tab determine the effective Rth(j-c).","metaTitle":"STPS30170CG Schottky Diode, 170 V, 15 A, D2PAK, Obsolete","metaDescription":"STPS30170CG dual common-cathode Schottky rectifier: 170 V Vr, 15 A per diode, 920 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":"STPS30170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Current - Reverse Leakage @ Vr":"20 µA @ 170 V","Voltage - DC Reverse (Vr) (Max)":"170 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"920 mV @ 15 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e692e2f62b93424f9f0fc28f63a211a6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS30170CG/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS30170CG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS30170CG when reusing this data.
