That 35 ns number is the key spec — it keeps the diode from hammering the MOSFET during hard-switching transitions, which directly affects efficiency and thermal rise in the rectifier stage. ## 12 A continuous rating — sizing the power path Rated for 12 A average rectified current with a forward voltage drop of 1.1 V at that current, the STTH1202D handles main rectification in a 200 V DC rail or secondary-side rectification in telecom bricks. ## TO-220-2 package — heatsink mounting and assembly The through-hole TO-220-2 package (supplier device package TO-220AC) is the standard power tab for bolting to a heatsink. The junction is rated to 175 °C max, so the thermal design needs a good interface — the tab carries the heat, and the mounting hole takes a screw or clip. No MSL concern with through-hole, but store the reels dry if the pouch seal is broken. No last-time-buy math needed for new designs — this one will be around for the foreseeable future.","metaTitle":"STTH1202D Fast Recovery Diode, 12A 200V 35ns trr TO-220-2","metaDescription":"STMicroelectronics STTH1202D standard fast recovery diode: 12A average rectified current, 200V reverse voltage, 35ns trr.","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":"Tube","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-2","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1202","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC","Reverse Recovery Time (trr)":"35 ns","Current - Reverse Leakage @ Vr":"10 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"12A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 12 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0b50321e38e980b44bfabb7b6eb840aa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1202D/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH1202D?","answer":"The reverse recovery time (trr) is 35 ns, which qualifies it as a fast recovery diode for switching power supply output stages and PFC boost converters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1202D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1202D when reusing this data.
