The 50 ns reverse recovery time (trr) places it in the ultrafast class, suited for hard-switching topologies where reverse-recovery losses and EMI matter — boost PFC stages, output rectification in 400 V bus converters, and interleaved or center-tapped secondary windings. ST lists the STTH20LCD06CG-TR as Obsolete. No last-time-buy window is open from the factory, and no direct successor is published in the lifecycle record. This part is not available through franchised distribution as a current-production line. Sourcing now runs through independent channels — brokers, excess inventory holders, and surplus stockists. The risk of counterfeit or relabeled parts rises when a device enters this phase, so traceability to a known date code and a trusted source is the main concern for a BOM line that still needs this exact order code. ## 50 ns trr — the switching-speed decision At 50 ns trr, this diode recovers fast enough for continuous-conduction-mode (CCM) boost PFC at switching frequencies up to around 100 kHz without excessive reverse-recovery losses. The 2 V forward drop at 10 A is typical for a 600 V ultrafast — a trade-off: lower Vf would mean slower recovery, higher Vf would mean more conduction loss. For a 10 A average load per diode, the conduction loss runs about 20 W per die at full current, so the D2PAK's thermal pad and board copper are part of the thermal design, not an afterthought. ## Common-cathode pair — topology fit The 1 Pair Common Cathode configuration means the two anodes are separate and the cathodes are tied together internally. That matches center-tapped secondary rectifiers (cathode to the output, anodes to each winding end) and interleaved boost PFC where two inductors share a common output rail. It also saves board space versus two discrete SOD-123 or SMB devices — one D2PAK replaces two separate packages, which simplifies layout and reduces placement cost.","metaTitle":"STTH20LCD06CG-TR 600V 10A Fast Recovery Diode, 50ns trr","metaDescription":"STTH20LCD06CG-TR is a 600V, 10A per diode fast recovery rectifier with 50ns trr in a D2PAK 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":"Tape & Reel (TR)","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":"STTH2","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"50 ns","Current - Reverse Leakage @ Vr":"1 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"2 V @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3207","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28db206b95c122f70216f078d5f9fdd4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for STTH20LCD06CG-TR?","answer":"For a pin-compatible replacement, look at the STTH20LCD06G (non-tape-and-reel variant) or the STTH20LCD06CG-TR's sibling STTH20LCD06G — same die, same ratings, different packing. For a functionally equivalent part from another brand, compare the 600 V, 10 A per diode, 50 ns trr, common-cathode D2PAK specification against offerings from ON Semiconductor (NRVTS series) or Vishay (HFA series).
