Each diode in the common-cathode pair handles 20 A continuous, so the package delivers 40 A total in a center-tap or interleaved PFC topology. Forward voltage drop is 1.55 V maximum at 15 A per diode — the conduction loss at full load runs about 31 W per leg, which the TO-220 package must sink through a heatsink with adequate thermal interface. Reverse leakage is 15 µA at the 600 V rated blocking voltage, a figure that rises with junction temperature up to the 175°C maximum operating junction temperature. The 85 ns trr is specified at standard test conditions; actual recovery in a hard-switched boost stage depends on the di/dt and the junction temperature at the switching instant. ## Obsolete — sourcing through the surplus channel Buyers should verify stock position; the surplus channel is the only supply path.","metaTitle":"STTH30L06CT Fast Recovery Diode, 600V 20A, TO-220, Obsolete","metaDescription":"STTH30L06CT dual common-cathode fast recovery diode, 600V Vr, 20A per diode, 85 ns trr, TO-220-3.","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":"STTH30","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Reverse Recovery Time (trr)":"85 ns","Current - Reverse Leakage @ Vr":"15 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.55 V @ 15 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c5b8b7f7bf809d039ce0faf8e6907f8b.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH30L06CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH30L06CT when reusing this data.
