The 170 V reverse voltage rating is the defining spec — it puts this part in the 48 V to 60 V bus space where a 100 V Schottky would leave no margin for inductive kickback or load-dump transients. The 5 A average current per diode (10 A total for the pair) suits output rectification in medium-power switch-mode supplies, OR-ing diodes in redundant power architectures, and freewheeling clamps in motor drives where the voltage rail exceeds 48 V. ## 920 mV forward drop — the loss trade-off Forward voltage sits at 920 mV at 5 A per diode — higher than a low-voltage Schottky, but that is the price of the 170 V blocking capability. The 10 µA reverse leakage at 170 V is typical for this voltage class and junction size. The fast recovery characteristic (≤ 500 ns, > 200 mA) is inherent to Schottky technology — no stored charge, so switching losses stay low in continuous-conduction-mode converters. ## Obsolete — the sourcing reality For sustainment of existing BOM lines, procurement should expect to source through independent distribution on a quoted-to-order basis.","metaTitle":"STPS10170CT Schottky Diode, 170 V, 5 A, TO-220-3, Obsolete","metaDescription":"STPS10170CT Schottky rectifier, 170 V reverse voltage, 5 A per diode, 920 mV Vf at 5 A, common-cathode pair in TO-220-3.","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","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS10170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","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":"$1.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3e80536fad96e3fb2f02ef2dc66f4718.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS10170CT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS10170CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS10170CT when reusing this data.
