Schottky construction gives a forward voltage of 920 mV at 8 A per leg, which keeps conduction losses lower than a comparable ultrafast recovery diode at this current density. The reverse leakage at 170 V is 15 µA, a typical figure for a 170 V Schottky — expect leakage to rise with junction temperature, so the thermal design should account for that at elevated loads. For a pin-compatible replacement, the STPS16140CT (140 V, 16 A, same TO-220-3 common-cathode footprint) is a candidate if the 170 V blocking voltage margin is not required — verify the reverse voltage headroom in your application before substituting. Maximum junction temperature is 175 °C, which allows operation in high-temperature environments such as power supplies and motor drives, provided the heatsink keeps Tj below that ceiling.","metaTitle":"STPS16170CT Schottky Diode, 170 V, 16 A, TO-220-3","metaDescription":"STPS16170CT dual common-cathode Schottky rectifier, 170 V reverse, 8 A per diode, 920 mV Vf at 8 A, 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","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS16170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","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":"920 mV @ 8 A","Current - Average Rectified (Io) (per Diode)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ccbe4daf3ae15ae46a9df3670aaea456.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS16170CT/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for STPS16170CT?","answer":"No official successor is listed. The STPS16140CT (140 V, 16 A, same TO-220-3 common-cathode package) is a pin-compatible alternative if the 170 V reverse voltage rating is not required. For applications that need the full 170 V blocking, check the STPS16170CR (D²PAK surface-mount variant) or a higher-voltage Schottky like the STPS20170CT (20 A, 170 V) — both are in the same STPS family."},{"question":"Can I use STPS16140CT instead of STPS16170CT?","answer":"Yes, if the reverse voltage requirement in your circuit is 140 V or less. The STPS16140CT shares the same TO-220-3 common-cathode package and 16 A total current rating. The 170 V version provides 30 V of additional blocking margin — if your design relies on that margin (e.g., for 120 VAC rectification with derating), the 140 V part may not be suitable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS16170CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS16170CT when reusing this data.
