It comes in a TO-220AC through-hole package. This part is typically used in power-factor correction (PFC) boost stages, output rectification in switched-mode power supplies, and freewheeling diodes in motor drives where fast switching and low recovery losses matter. ## 90 ns trr — switching loss impact A 90 ns trr at 30 A and 600 V puts this diode in the ultrafast class. In a hard-switched PFC stage running at 50-100 kHz, that recovery time keeps the reverse-recovery charge low enough that the MOSFET or IGBT turn-on losses stay manageable. If you are pushing toward 150 kHz, you will want to check the recovery charge (Qrr) in the full datasheet — the trr alone is a good first filter, but Qrr is the number that drives the loss calculation. ## Obsolete — plan the replacement now STMicroelectronics no longer manufactures this diode. Any stock you find is new-old-stock or surplus from distribution channels. ## Sourcing the STTH30L06D today Because this part is obsolete, it is not available through the standard factory supply chain. We source it through our independent distribution network — surplus inventories, overstock from OEMs, and verified broker channels. If you need a production quantity or a long-term supply plan, the smarter move is to identify and qualify a drop-in replacement now rather than chase shrinking stock.","metaTitle":"STTH30L06D 600V 30A Fast Recovery Diode, TO-220AC, Obsolete","metaDescription":"STTH30L06D is a 600 V, 30 A fast recovery diode with 90 ns trr in a TO-220AC 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","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-2","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH30","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC","Reverse Recovery Time (trr)":"90 ns","Current - Reverse Leakage @ Vr":"25 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"30A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.55 V @ 30 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/81d15526a69cd46fda2072ba844b898a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the STTH30L06D?","answer":"We source the STTH30L06D through independent distribution channels — surplus stock and verified broker inventories.
