The D2PAK surface-mount package handles the thermal load through the exposed tab, which is the cathode common node. Typical applications include switch-mode power supply secondary-side rectification, freewheeling diodes in motor drives, and OR-ing diodes in redundant power architectures. ST lists the STPS10L45CG-TR as obsolete. For existing designs that need this exact footprint and rating, the independent channel is the only supply route. The forward voltage and reverse leakage at 45 V (150 µA maximum) are the key parametric targets for a replacement. ## What the 530 mV forward voltage means for your thermal budget At 5 A per diode, 530 mV forward drop produces about 2.65 W of conduction loss per diode. In a common-cathode pair carrying 5 A total, the loss splits across the two junctions. If the board runs hot or airflow is limited, a lower-Vf Schottky in a larger package may be needed.","metaTitle":"STPS10L45CG-TR Schottky Diode, 45 V, 5 A per Diode, D2PAK","metaDescription":"STPS10L45CG-TR Schottky rectifier: 45 V reverse voltage, 5 A average per diode, 530 mV forward voltage at 5 A, 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)","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":"STPS10","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Current - Reverse Leakage @ Vr":"150 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"530 mV @ 5 A","Current - Average Rectified (Io) (per Diode)":"5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b0f3afb4bc9f7c4d2f11a33b3be4149.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS10L45CG-TR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS10L45CG-TR obsolete?","answer":"Yes, ST lists the STPS10L45CG-TR as obsolete.
