The fast-recovery characteristic (≤500 ns, >200 mA) suits it for switching power supplies and freewheeling diodes in DC-DC converters where Schottky's low Vf and fast turn-off reduce switching loss. STMicroelectronics lists the STPS10L45CG as obsolete. The 45 V reverse voltage (Vr) sets the maximum DC blocking voltage — adequate for 12 V and 24 V rails with margin, but tight for 48 V systems where a 60 V part would be preferred. The 530 mV forward drop at 5 A per diode means each leg dissipates about 2.65 W at full rated current; the D2PAK's exposed tab on the PCB carries that heat, so the layout needs a decent copper area or forced airflow to keep the junction below the 150 °C maximum.","metaTitle":"STPS10L45CG Schottky Rectifier, 45V 5A per Diode, D2PAK","metaDescription":"STPS10L45CG dual Schottky rectifier, 45V reverse, 5A per diode, 530mV Vf.","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/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS10L45CG?","answer":"No official successor is listed by STMicroelectronics.
