STMicroelectronics lists the STPS6045CPIRG as obsolete. ## Parametric fit for high-current rectification The common-cathode pair is a natural fit for center-tap full-wave rectifiers and half-bridge topologies in switch-mode power supplies and DC-DC converters. The 45 V reverse voltage covers 24 V and 36 V rails with margin; the 30 A per-diode rating supports output stages up to about 60 A total when the two diodes are paralleled. Reverse leakage is 500 µA at 45 V — a figure that rises with junction temperature, so thermal management of the TOP-3I tab is critical above 100°C.","metaTitle":"STPS6045CPIRG Schottky Diode, 45V 30A Common Cathode, TOP-3I","metaDescription":"STPS6045CPIRG Schottky rectifier, 45V Vr, 30A per diode, 630mV Vf, common cathode, TOP-3I through-hole.","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":"Bulk","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TOP-3 Insulated","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS60","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TOP-3I","Current - Reverse Leakage @ Vr":"500 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"630 mV @ 30 A","Current - Average Rectified (Io) (per Diode)":"30A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7899c3d6e99d3a273b1360b039d69bfb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS6045CPIRG/alternatives.json"},"ai":{"faq":[{"question":"Is STPS6045CPIRG obsolete?","answer":"Yes, STMicroelectronics has marked the STPS6045CPIRG as obsolete.
