The D2PAK (TO-263) exposed tab must be soldered to a minimum 2 oz copper plane of at least 6 cm² to keep the junction below 175°C. Without that thermal pad area, the 20 A rating is theoretical. Reverse leakage is 10 µA at 200 V and 25°C — negligible at room temperature, but it doubles every 10°C rise. At 150°C junction the leakage can exceed 1 mA, adding to the thermal load. The 175°C absolute maximum junction rating gives headroom for high-ambient power loops like boost PFC stages or motor-drive DC bus snubbers. ## Obsolete — no official successor on record STMicroelectronics has not published a direct replacement order code for this part. The base product number STTH2 covers a family of 200 V fast recovery diodes in various packages (D2PAK, DPAK).","metaTitle":"STTH2002G 20A 200V Fast Recovery Diode, D2PAK, 40 ns trr","metaDescription":"STMicroelectronics STTH2002G 20A 200V fast recovery diode in D2PAK. 40 ns trr, 175°C Tj max.","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":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH2","Capacitance @ Vr, F":"-","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"40 ns","Current - Reverse Leakage @ Vr":"10 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"20A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 20 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e8f0e7725b98d55acd230e6cbb65994.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STTH2002G obsolete?","answer":"Yes, the STTH2002G is listed as Obsolete."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH2002G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH2002G when reusing this data.
