Packaged in a through-hole TO-251-3 IPAK (TO-251AA), it is intended for low-voltage, high-current applications such as switch-mode power supply output rectification, freewheeling diodes, and OR-ing diodes in redundant power systems. ## Ratings and design margin The 10 A per-diode average rating is specified without a heatsink condition — the IPAK tab carries the heat, so a PCB copper area or clip-on heatsink is assumed for continuous operation near the limit. Reverse leakage is 100 µA at 45 V, typical for a Schottky of this voltage class; it rises with junction temperature, so a hot environment increases the quiescent loss in OR-ing applications.","metaTitle":"STPS2045CH Schottky Diode, 45V 10A Common Cathode, Obsolete","metaDescription":"STPS2045CH dual Schottky rectifier, 45V Vrrm, 10A per diode, 840mV Vf, TO-251 IPAK.","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","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-251-3 Short Leads, IPak, TO-251AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS2045","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"IPAK (TO-251)","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":"840 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/35b478c0e70e5704c079995c315a32ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for STPS2045CH?","answer":"No official replacement order code is recorded for the STPS2045CH in the available lifecycle data.
