Forward voltage is specified at 670 mV at 20 A, keeping conduction losses manageable in high-current rectification or OR-ing applications. The part carries AEC-Q101 automotive qualification, making it suitable for under-hood power supplies, alternator rectification, and DC-DC converter output stages where reliability screening and temperature range matter. ## 175°C junction — thermal headroom for tight enclosures Operating junction temperature spans -40°C to 175°C, which is the extended automotive grade. In a sealed ECU or motor-drive compartment where ambient can reach 105°C, the 175°C Tj max provides derating margin for the 20 A load. The TO-220 tab is the primary heat path; a proper heatsink or chassis mount is expected for sustained current near the rating. ## Fast recovery characteristic — switching loss context Listed as a fast recovery diode with trr ≤ 500 ns at >200 mA. For a Schottky, this is a conservative recovery spec — the Schottky barrier inherently has minimal stored charge, so switching losses are low even without a fast-recovery label. The 500 ns bound is a datasheet guarantee for the inductive-switching case; in practice the part behaves as a majority-carrier device with negligible reverse recovery. ## AEC-Q101 and active lifecycle","metaTitle":"STPS41H100CTY Schottky Diode, 100V 20A, TO-220-3, AEC-Q101","metaDescription":"STPS41H100CTY automotive Schottky rectifier, 100 V reverse voltage, 20 A per diode, 670 mV forward drop, TO-220-3, AEC-Q101 qualified.","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","Package":"Tube","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS41","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"10 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"670 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9e5c7a7b0cc7ef0a9354340d5bf3702f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS41H100CTY/alternatives.json"},"ai":{"faq":[{"question":"Can STPS41H100CTY replace STPS41H100CT?","answer":"The STPS41H100CTY is the automotive-qualified (AEC-Q101) variant of the base STPS41H100CT.
