In a 100 kHz boost PFC or a forward-converter output stage, a slower diode would dump charge back into the switch at turn-off, raising junction temperature and EMI. At 990 mV forward drop at 8 A, the conduction loss per diode is roughly 7.9 W at full rated current — the TO-220 tab needs a thermal path to keep the junction under 150°C. STMicroelectronics lists the STPR1620CT as obsolete. If a pin-compatible replacement is needed, a parametric search for a TO-220-3 common-cathode pair with ≥200 V Vr and ≤30 ns trr is the practical next step.","metaTitle":"STPR1620CT Fast Recovery Diode, 200 V, 30 ns trr, TO-220","metaDescription":"STPR1620CT dual common-cathode fast recovery diode: 200 V, 8 A per diode, 30 ns trr, 990 mV 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":"Tube","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPR1620","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":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"990 mV @ 8 A","Current - Average Rectified (Io) (per Diode)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPR1620CT/alternatives.json"},"ai":{"faq":[{"question":"Is STPR1620CT obsolete?","answer":"Yes, STMicroelectronics has marked the STPR1620CT as obsolete.
