The 170 V reverse voltage rating gives headroom for 48 V and 72 V bus rails, and can handle the reflected voltage in a 100 V input flyback converter. The 900 mV forward drop at 10 A per diode is typical for a 170 V Schottky — expect about 9 W dissipation per diode at full load, so the TO-220 tab needs a heatsink for continuous operation above a few amps. The 15 µA reverse leakage at 170 V is a room-temperature figure; leakage doubles roughly every 10°C rise, so at 125°C junction count on several milliamps — factor that into your standby-loss budget. ## Package and rework — the TO-220 is your friend The TO-220-3 through-hole package is about as rework-friendly as it gets. The metal tab takes a soldering iron or hot-air gun without drama, and the three leads are clearly spaced — no risk of bridging. Mount it with a TO-220 heatsink clip or a screw through the tab hole. The tube shipping medium keeps the leads straight, but the parts are robust enough to survive being dropped into a parts bin. ## Lifecycle and supply — active, no LTB risk For dual-sourcing, look at other 170 V, 20 A common-cathode Schottkys in TO-220 from major vendors — pin-compatible parts exist, but verify the Vf and leakage trade-offs against your thermal budget.","metaTitle":"STPS20170CT Schottky Diode, 170 V, 20 A, TO-220-3","metaDescription":"STPS20170CT dual common-cathode Schottky rectifier, 170 V reverse voltage, 10 A per diode, TO-220-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS20170","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":"900 mV @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5b673d57dc3f687e65054cdc247b24dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20170CT/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum junction temperature of STPS20170CT?","answer":"The maximum junction temperature is 175°C.
