It is a standard diode type intended for high-frequency rectification in power conversion stages such as power-factor-correction boost circuits, flyback snubbers, and output rectification in offline switch-mode power supplies up to a few hundred watts. The 600 V blocking voltage suits it for universal-input AC/DC designs, while the 50 ns trr keeps switching losses low in continuous-current-mode topologies. A 50 ns trr places this diode in the ultrafast class, well below the 500 ns threshold that defines fast recovery in the spec. In a PFC boost stage running at 65–100 kHz, that 50 ns recovery cuts the reverse-recovery charge and the associated turn-off loss compared to a slower 200 ns part. The trade-off is a forward voltage of 2 V at 10 A, which is higher than a standard recovery rectifier — you trade conduction loss for switching loss, which is the right call in hard-switched topologies where the diode's recovery dominates the dissipation. ## 10 A average current in a DPAK — thermal design matters Rated for 10 A average rectified current at a 175 °C maximum junction temperature, the DPAK package needs a well-designed copper land on the PCB to pull heat out of the tab. At 10 A with a 2 V forward drop, the conduction loss alone is 20 W — that is a lot for a DPAK without a heatsink. In practice, the part is often run at lower average currents (3–5 A) in continuous boost stages, or used in discontinuous-mode flyback where the RMS current is lower. The 5 µA reverse leakage at 600 V is tight for a 175 °C rated junction, but expect it to multiply at high temperature. The STTH10LCD06SB-TR is marked obsolete by STMicroelectronics. Each lot should be date-code traced and physically inspected — DPAK parts are sometimes re-marked or pulled from scrapped boards. The forward voltage and reverse recovery time should be bench-verified on a sample from any non-franchised source, particularly if the parts show inconsistent laser marking.","metaTitle":"STTH10LCD06SB-TR STMicroelectronics 10A 600V Ultrafast Diode","metaDescription":"STTH10LCD06SB-TR is a 10A, 600V ultrafast rectifier with 50ns reverse recovery time in DPAK.","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":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH10","Capacitance @ Vr, F":"-","Supplier Device Package":"DPAK","Reverse Recovery Time (trr)":"50 ns","Current - Reverse Leakage @ Vr":"5 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"10A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"2 V @ 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/86926caed109a38abd89fbf6870f7157.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH10LCD06SB-TR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STTH10LCD06SB-TR?","answer":"A pin-compatible replacement would need to match the 10 A, 600 V, 50 ns trr, DPAK footprint.
