The fast-recovery speed (≤ 500 ns, > 200 mA) suits it for high-frequency switching in power supplies, DC-DC converters, and freewheeling diode applications where Schottky's low forward drop and fast switching reduce losses. That means STMicroelectronics has ended production; no last-time-buy window remains from the factory. ## Ratings that decide the fit The 170 V reverse voltage gives headroom for 48 V and 72 V bus rails with derating. The 5 A per diode average current is the continuous rating — peak repetitive current will be higher, but the junction temperature limit of 175 °C (max) is the real constraint in a cramped DPAK layout. The 10 µA reverse leakage at 170 V is typical for a 170 V Schottky; expect it to rise with temperature, so factor that into standby-loss budgets. ## Rework and board-fit notes DPAK (TO-252-3) is a single-gauge leadframe with a large exposed tab. It reflows well with standard hot-air profiles — the tab soaks heat, so preheat the board to 100–120 °C before lifting the part to avoid pad damage. Orientation is marked by a chamfer on the body, but it is subtle — check under magnification before placing.","metaTitle":"STPS10170CB Schottky Diode, 170V 5A Common Cathode, DPAK","metaDescription":"STPS10170CB dual Schottky rectifier, 170V reverse voltage, 5A per diode, 920mV Vf at 5A.","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-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS10170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"DPAK","Current - Reverse Leakage @ Vr":"10 µA @ 170 V","Voltage - DC Reverse (Vr) (Max)":"170 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"920 mV @ 5 A","Current - Average Rectified (Io) (per Diode)":"5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3e80536fad96e3fb2f02ef2dc66f4718.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS10170CB/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for STPS10170CB?","answer":"A direct pin-compatible replacement is not listed in the official record. For a new design, look for a dual-Schottky in DPAK with 170 V reverse voltage and 5 A per diode — ST's STPS10xxCB series or equivalent from other manufacturers are the starting point.
