Buyers should qualify any surplus lot for date-code consistency and original packaging — sealed factory reels with uniform date-codes are preferred over mixed-date auction lots that may be repackaged returns. The 170 V reverse voltage rating provides headroom on a 48 V or 100 V bus, but it is not a 200 V part — a 48 V supply with 20 % transient margin stays safe; a 120 V bus would exceed the rating. The 15 A per-diode average current (total 30 A from the common-cathode pair) is the continuous rating; peak repetitive currents should be checked against the datasheet's surge curves. The 920 mV forward drop at 15 A is typical for a 170 V Schottky — higher than a 45 V Schottky's drop but necessary for the voltage class. The 20 µA reverse leakage at 170 V is moderate; expect it to rise with junction temperature, so thermal design should account for leakage-induced self-heating at high line and elevated ambient.","metaTitle":"STPS30170CT Schottky Diode, 170 V, 15 A, TO-220, Obsolete","metaDescription":"STPS30170CT Schottky rectifier: 170 V reverse voltage, 15 A average per diode, 920 mV forward drop at 15 A, TO-220 package.","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":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS30170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","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/STPS30170CT/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of STPS30170CT?","answer":"The STPS30170CT is a dual Schottky diode with common-cathode configuration, rated 170 V reverse voltage, 15 A average rectified current per diode, 920 mV forward drop at 15 A, 20 µA reverse leakage at 170 V, and a 175°C maximum junction temperature.
