The buyer should qualify an alternative part for new designs or plan for a one-time buy of remaining available stock for legacy BOM lines. ## 650 V, 8 A, 25 ns trr — what these ratings mean for the power stage The STTH8BC065DI is a standard fast-recovery epitaxial diode rated for 650 V DC reverse voltage and 8 A average rectified current. The 25 ns reverse recovery time (trr) places it in the fast-recovery class, suitable for continuous-conduction-mode boost stages, PFC front ends, and output rectification in switching power supplies where reverse-recovery losses directly affect efficiency and thermal stress. The 650 V rating provides margin for 400 V DC bus rails and universal-input PFC stages, though the designer should verify derating against the peak repetitive voltage in the specific topology. ## TO-220AC insulated package — mounting and thermal considerations The STTH8BC065DI is supplied in a TO-220AC insulated package (TO-220-2 Insulated, supplier device package TO-220AC ins). The through-hole mounting suits point-of-load heatsinking on a main PCB or a separate heatsink bracket.","metaTitle":"STTH8BC065DI Fast Recovery Diode, 650V 8A 25ns trr","metaDescription":"STTH8BC065DI 650V 8A fast recovery diode from STMicroelectronics. 25 ns trr, TO-220AC insulated package.","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-220-2 Insulated, TO-220AC","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH8BC","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC ins","Reverse Recovery Time (trr)":"25 ns","Voltage - DC Reverse (Vr) (Max)":"650 V","Current - Average Rectified (Io)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4724b183869646029efd5a510336588f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH8BC065DI/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of the STTH8BC065DI?","answer":"The reverse recovery time (trr) is 25 ns, which qualifies it as a fast-recovery diode for switching power supply applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH8BC065DI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH8BC065DI when reusing this data.
