Its 50 ns reverse recovery time places it in the ultrafast class, suited for continuous-current-mode boost PFC stages, output rectification in 48 V to 120 V DC-bus supplies, and snubber clamp circuits where stored charge recovery losses matter. ## 50 ns trr — switching loss and snubber fit The 50 ns reverse recovery time is the headline switching parameter. In a hard-switched PFC boost stage at 100 kHz, a 30 A diode with 50 ns trr keeps the recovery charge low enough that the MOSFET turn-on loss stays manageable without a saturable-reactor snubber. The 1.05 V forward drop at 30 A is typical for a 200 V planar fast-recovery die — the conduction loss at full load is about 31.5 W, which the DO-247 package can dissipate with a heatsink and forced air. ## 175°C junction — thermal headroom for sustained load Rated for a maximum junction temperature of 175°C, the STTH3002W can sustain high-current operation in confined enclosures where ambient temperatures reach 85°C or more. The 20 µA reverse leakage at 200 V, 25°C, rises with junction temperature — at 150°C the leakage may approach several milliamps, which the designer should include in the standby-loss budget for a continuously running supply. STMicroelectronics lists the STTH3002W as obsolete.","metaTitle":"STTH3002W Fast Recovery Diode, 30A 200V 50ns trr DO-247","metaDescription":"STTH3002W 30A 200V fast recovery diode, 50 ns trr, DO-247 through-hole.","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":"DO-247-2 (Straight Leads)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH30","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-247","Reverse Recovery Time (trr)":"50 ns","Current - Reverse Leakage @ Vr":"20 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"30A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.05 V @ 30 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/810e07864812c3d13690b4f44ac14aef.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the specifications of STTH3002W?","answer":"The STTH3002W is a 30 A, 200 V fast recovery diode with a 50 ns reverse recovery time.
