An 85 ns trr at 2 A forward current and 600 V blocking gives this diode a recovery charge low enough to keep switching losses manageable in a 70–100 kHz PFC stage. At turn-off the stored charge clears quickly, so the MOSFET or IGBT in the same leg sees less current overshoot and lower EMI. The 1.3 V forward drop at 2 A is typical for a 600 V fast-epitaxial die — the trade-off is conduction loss against switching speed. ## Package and footprint — DO-214AA SMB The SMB (DO-214AA) package is a common surface-mount outline for 2 A-class diodes. The cathode is the tab side — the PCB copper pad under the tab should be sized for thermal dissipation. Standard SMB footprint with a 12×12 mm cathode pad is a reasonable starting point.","metaTitle":"STTH2L06U Fast Recovery Diode, 600 V, 2 A, 85 ns trr, SMB","metaDescription":"STMicroelectronics STTH2L06U standard fast recovery diode, 600 V, 2 A, 85 ns trr, DO-214AA SMB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH2","Capacitance @ Vr, F":"-","Supplier Device Package":"SMB","Reverse Recovery Time (trr)":"85 ns","Current - Reverse Leakage @ Vr":"2 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.3 V @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e5e2c639a4fdf4002874f63161cf875.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is STTH2L06U's reverse recovery time?","answer":"The STTH2L06U has a reverse recovery time (trr) of 85 ns, measured at standard test conditions for a fast recovery diode. This trr is suitable for continuous-conduction-mode PFC and flyback converters switching in the 70–100 kHz range."},{"question":"Can STTH2L06U be used in high frequency applications?","answer":"With an 85 ns trr, the STTH2L06U is suited for switching frequencies up to about 100 kHz in typical PFC and flyback topologies.
