The 60 µA reverse leakage at 170 V and fast recovery ≤500 ns suit it for high-frequency switching in automotive DC-DC converters, alternator rectifiers, and PFC stages. AEC-Q101 qualification and a 175°C maximum junction temperature confirm it for under-hood and engine-bay environments where ambient temperatures push 125°C. ## AEC-Q101 and 175°C Tj – the deployment envelope The 175°C junction maximum gives thermal headroom for continuous 30 A conduction in a 105°C ambient when the TO-247 package is bolted to a heatsink. The ECOPACK®2 finish is RoHS-compliant and halogen-free, so no exemption paperwork on the BOM. ## Package and mounting – TO-247 Long Leads The TO-247-3 with long leads is a through-hole package designed for screw-mount or clip-mount to a heatsink. The long leads give extra clearance for thick heatsink fins or bus-bar connections. The common-cathode configuration means the two anodes are separate pins, the cathode is the tab – orientation is marked on the body. Through-hole mounting is straightforward for rework; the tab can be soldered or bolted.","metaTitle":"STPS61170CWLY Schottky Diode, 170V 30A, AEC-Q101, TO-247-3","metaDescription":"STPS61170CWLY – STMicro dual Schottky rectifier, 170V Vr, 30A per diode, ≤500ns recovery, AEC-Q101 automotive, TO-247-3.","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":"Automotive, AEC-Q101, ECOPACK®2","Package":"Tube","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-247-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS61170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-247 Long Leads","Current - Reverse Leakage @ Vr":"60 µA @ 170 V","Voltage - DC Reverse (Vr) (Max)":"170 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"840 mV @ 30 A","Current - Average Rectified (Io) (per Diode)":"30A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8888","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/332f353eb71599680cd419e8d0b33600.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS61170CWLY/alternatives.json"},"ai":{"faq":[{"question":"Does STPS61170CWLY meet AEC-Q101 automotive qualification?","answer":"Yes.
