Its 50 ns reverse recovery time (trr) keeps the switching node from ringing hard when the diode turns off — that means less snubber loss and a cleaner EMI signature than a standard recovery part would deliver at this current level. ## Conduction loss and thermal budget at 30 A Forward voltage is 1.05 V maximum at 30 A, which puts the conduction loss at 31.5 W before you factor in the switching loss. The D2PAK (TO-263) tab is the cathode terminal — the PCB copper area under that tab sets the junction-to-ambient thermal resistance. At 175 °C maximum junction temperature, the design needs a heatsink or a substantial copper pour to keep the die inside its SOA at full load. STMicroelectronics lists the STTH3002G as obsolete. No factory orders are accepted; the only channel is independent distribution, where parts are sourced from surplus or last-time-buy inventory. ## Package and footprint — D2PAK placement notes The STTH3002G ships in a D2PAK (TO-263AB) surface-mount package with two leads plus a large tab. The tab is electrically the cathode — the PCB footprint must connect it to the output rail with enough copper area to sink the heat.","metaTitle":"STTH3002G Fast Recovery Diode, 30A 200V, 50ns trr, D2PAK","metaDescription":"STTH3002G 30A 200V fast recovery diode, 50ns trr, 1.05V Vf at 30A, D2PAK surface mount.","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","Diode Type":"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":"STTH30","Capacitance @ Vr, F":"-","Supplier Device Package":"D2PAK","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":"$2.9200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/810e07864812c3d13690b4f44ac14aef.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of the STTH3002G?","answer":"The STTH3002G has a reverse recovery time (trr) of 50 ns, which qualifies it as a fast-recovery diode (speed rating: Fast Recovery =< 500 ns, > 200 mA).
