It comes in the DOP3I insulated through-hole package, rated for a maximum junction temperature of 175 °C. ## 50 ns trr at 30 A — the spec that drives the switching loss budget The 50 ns reverse recovery time at 30 A average forward current is the headline parameter. The part is obsolete. ## 200 V reverse voltage, 1.05 V forward drop — conduction loss and voltage headroom Rated for 200 V DC reverse maximum, the STTH3002PI fits into 170–200 V DC-link buses commonly found in single-phase PFC outputs. The 1.05 V forward drop at 30 A gives a conduction loss of about 31.5 W at full rated current — a sizeable figure that demands a heatsink with good thermal contact to the DOP3I package. The insulated DOP3I-2 body means you can bolt the diode directly to a grounded heatsink without an insulating pad, which simplifies assembly in high-voltage sections. ## Obsolete — no official successor listed STMicroelectronics lists the STTH3002PI as obsolete. For a BOM line that still calls this exact part, the supply path is through independent distribution — last-time-buy lots or surplus inventory. The reverse leakage at 200 V is 20 µA, which is typical for a fast recovery diode of this voltage class; date-code provenance matters more than parametric matching when buying obsolete stock.","metaTitle":"STTH3002PI Fast Recovery Diode, 30A 200V 50ns trr, DOP3I-2","metaDescription":"STTH3002PI is an obsolete STMicroelectronics 30A 200V fast recovery diode with 50ns trr.","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":"Through Hole","Package / Case":"DOP3I-2 Insulated (Straight Leads)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH3002","Capacitance @ Vr, F":"-","Supplier Device Package":"DOP3I","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":"$2.9500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/810e07864812c3d13690b4f44ac14aef.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for the STTH3002PI?","answer":"No official replacement or successor order code is listed by STMicroelectronics for the STTH3002PI.
