ST lists this part as Obsolete. That means new-design starts should look at current Schottky pairs in the same package and voltage class. The 60 V reverse voltage gives you about 20 % derating on a 48 V bus — comfortable for most 48 V telecom or 24 V industrial rails, but tight if you need margin on a 48 V nominal with transients. The 595 mV forward drop at 20 A is typical for a 60 V Schottky at this current density — expect it to rise with junction temperature. The 110 µA reverse leakage at 60 V is a reminder that Schottkys trade higher leakage for lower Vf; at elevated junction temperatures (max 150 °C,) leakage climbs significantly, so thermal design matters in high-ambient or enclosed environments. ## Package and mounting note The D²Pak (TO-263-3) is a surface-mount power package with a large metal tab for heat sinking. It is the same footprint as D²Pak variants, so any current-production 60 V Schottky pair in D²Pak should land on the same PCB pads. The tab is common cathode — keep that in mind for the copper pour and thermal vias. No lab bench needed for a swap, but the tab needs a good solder joint to the board copper; a hot-air station or reflow oven is the right tool, not a hand iron.","metaTitle":"STPS40M60CG-TR Schottky diode, 60 V, 20 A per diode","metaDescription":"STPS40M60CG-TR Schottky rectifier, 60 V reverse voltage, 20 A average per diode, common-cathode pair in D²Pak.","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":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS40","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D²PAK","Current - Reverse Leakage @ Vr":"110 µA @ 60 V","Voltage - DC Reverse (Vr) (Max)":"60 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"595 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a12e6ce2e6e01e0d588d457fafda8d4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS40M60CG-TR/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of STPS40M60CG-TR?","answer":"The average rectified current is 20 A per diode.

However, it uses low-drop Schottky technology, so the forward voltage and reverse leakage will differ. Verify the Vf vs. Ir curves in your operating conditions before swapping.
