In a 100 kHz boost PFC stage, the recovery charge per cycle is low enough that the diode can share the heatsink with the MOSFET without exceeding the 175 °C junction limit, provided the forward voltage drop of 1.5 V at 8 A is factored into the conduction loss calculation. The 175 °C junction rating demands a low-thermal-resistance layout — the tab solder area and via count under the package set the continuous current ceiling, not the 8 A silicon rating alone.","metaTitle":"STTH16R04CG Fast Recovery Diode, 400 V, 8 A, 50 ns trr","metaDescription":"STTH16R04CG dual common-cathode fast recovery diode, 400 V, 8 A per diode, 50 ns trr, 175 °C junction.","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":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH16","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"50 ns","Current - Reverse Leakage @ Vr":"10 µA @ 400 V","Voltage - DC Reverse (Vr) (Max)":"400 V","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.5 V @ 8 A","Current - Average Rectified (Io) (per Diode)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/47e462c64726a733f35f3f4b51874148.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH16R04CG?","answer":"The reverse recovery time (trr) is 50 ns, making it suitable for fast-switching applications such as PFC and output rectification in SMPS."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH16R04CG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH16R04CG when reusing this data.
