Each diode is rated for 45 V reverse voltage with a forward drop of 570 mV at 7.5 A — low enough to keep conduction losses manageable in 12 V and 24 V rail rectification, OR-ing, and freewheeling circuits. ## Package and mounting — D2PAK practicalities Surface-mount D2PAK (TO-263-3, two leads plus tab) with the tab as the common cathode. The Tape & Reel suffix (-TR) means it ships on a 13-inch reel — standard for pick-and-place. STMicroelectronics lists the STPS1545CG-TR as Active (current product status).","metaTitle":"STPS1545CG-TR Schottky Diode, 45 V, 7.5 A per Diode, D2PAK","metaDescription":"STPS1545CG-TR dual common-cathode Schottky rectifier: 45 V Vrrm, 7.5 A per diode, 570 mV Vf at 7.5 A, 175°C Tj max.","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":"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":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS1545","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Current - Reverse Leakage @ Vr":"100 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"570 mV @ 7.5 A","Current - Average Rectified (Io) (per Diode)":"7.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd32a02f6ef99505c5bdfa6109d2e4ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS1545CG-TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STPS1545CG and STPS1545CG-TR?","answer":"The die and electrical specs are identical. The -TR suffix indicates Tape & Reel packaging (13-inch reel for automated assembly). The base STPS1545CG ships in tube or tray. Choose -TR for pick-and-place; use the non-TR variant for hand-assembly or low-volume builds."},{"question":"What is STPS1545CG-TR's listed speed?","answer":"The datasheet classifies it as Fast Recovery: ≤ 500 ns, > 200 mA (Io). For a Schottky, this is the standard switching speed — no reverse-recovery tail, so it works well in 50–200 kHz SMPS output rectification and freewheeling diodes."},{"question":"Is STPS1545CG-TR RoHS compliant?","answer":"STMicroelectronics lists the STPS1545CG-TR as RoHS compliant.
