It is rated for a maximum DC reverse voltage of 150 V and delivers an average rectified current of 15 A per diode. The forward voltage drop is specified at 920 mV maximum at 15 A, and the junction can operate up to 175°C, giving the part a wide thermal margin in high-current rectification and OR-ing applications. At 15 A average per diode, the STPS30150CG suits output rectification in switch-mode power supplies and DC-DC converters where the total load splits across two paralleled Schottkys in a common-cathode pair. The 150 V reverse voltage covers 48 V and 72 V bus rails with derating headroom. The 920 mV forward drop at 15 A is typical for a 150 V-class Schottky at this current density — expect higher Vf at elevated junction temperature, which the 175°C rating accommodates for designs that push the thermal envelope. Reverse leakage is 6.5 µA at 150 V, a figure that rises with temperature; the common-cathode layout simplifies the PCB trace routing for the output rail. ## Lifecycle reality — obsolete, available through independent channels Procurement for this part runs through independent distribution and surplus stock.","metaTitle":"STPS30150CG Schottky Diode, 15A, 150V, D²PAK, Obsolete","metaDescription":"STPS30150CG Schottky rectifier, 15A per diode, 150V Vr, 920mV Vf at 15A, common cathode, 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":"Tube","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":"STPS30150","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D²PAK","Current - Reverse Leakage @ Vr":"6.5 µA @ 150 V","Voltage - DC Reverse (Vr) (Max)":"150 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"920 mV @ 15 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/03ace0762d35c9ed3820ea5794c1609e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS30150CG/alternatives.json"},"ai":{"faq":[{"question":"What is the direct replacement for STPS30150CG?","answer":"STMicroelectronics has not published an official direct replacement for the STPS30150CG.
