The pair shares a cathode in a single TO-220-3 package, which simplifies layout for center-tapped windings or dual-diode boost converters. The 30 ns reverse recovery time places this part in the fast-recovery class (≤ 500 ns per the generic classification). In a 100 kHz PFC or flyback converter, that trr keeps the recovery charge low enough to avoid excessive turn-on loss in the MOSFET and reduce ringing on the switch node. The forward drop is 990 mV at 5 A, which is a reasonable conduction loss trade-off for the speed. If your design runs above 200 kHz, you would typically step to an ultrafast or SiC diode; below 50 kHz, a standard recovery part would do. STMicroelectronics lists the STPR1020CT as Obsolete. A buyer should confirm availability and current pricing at quote time — the spot market is the channel for this one.","metaTitle":"STMicroelectronics STPR1020CT Fast Recovery Diode, 200 V","metaDescription":"STPR1020CT obsolete fast recovery diode from STMicroelectronics. 200 V, 5 A per diode, 30 ns trr, TO-220-3 common cathode pair.","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":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPR1020","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Reverse Recovery Time (trr)":"30 ns","Current - Reverse Leakage @ Vr":"50 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"-65°C~150°C","Voltage - Forward (Vf) (Max) @ If":"990 mV @ 5 A","Current - Average Rectified (Io) (per Diode)":"5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5400","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPR1020CT/alternatives.json"},"ai":{"faq":[{"question":"Is STPR1020CT obsolete?","answer":"Yes, STMicroelectronics lists the STPR1020CT as Obsolete.
