Each diode is rated for a maximum DC reverse voltage of 170 V and an average rectified current of 10 A per diode. The forward voltage drop is specified at 900 mV maximum at 10 A, and the device is classified as Fast Recovery with a recovery time ≤ 500 ns at > 200 mA. ## 170 V blocking, 10 A per leg — where it fits With a 170 V reverse voltage and 10 A average current per diode, this common-cathode pair is sized for output rectification in 48 V to 100 V DC-DC converters, freewheeling diodes in motor drives, and OR-ing diodes in redundant power supplies. The 900 mV forward drop at full rated current is typical for a 170 V Schottky — expect higher conduction loss than a lower-voltage Schottky but necessary for the voltage headroom. The junction temperature rating of 175°C maximum gives thermal margin in high-ambient or forced-air designs. STMicroelectronics lists the STPS20170CR as Obsolete. Buyers should qualify a replacement for new designs or bridge supply through the surplus channel for legacy production.","metaTitle":"STPS20170CR Schottky Diode, 170V 10A Common Cathode","metaDescription":"STPS20170CR dual Schottky rectifier: 170 V Vr, 10 A per diode, 900 mV Vf at 10 A, TO-262AA (I2PAK).","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-262-3 Long Leads, I²Pak, TO-262AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS20170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"I2PAK","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":"900 mV @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d27139a2255bf6596b7cdcb82b3b59c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20170CR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS20170CR?","answer":"No official replacement part number is recorded in the lifecycle data.
