Its 25 ns reverse recovery time keeps switching losses low in continuous-conduction-mode PFC stages or hard-switched flyback converters. ST lists the STTH1302CFP as obsolete. If you have an active BOM line using this diode, the common-cathode TO-220FP footprint and 200 V / 6.5 A / 25 ns trr window narrows the replacement search — look for a same-pinout ultrafast in the STTH or equivalent family. ## 25 ns trr — why it matters for the switching loop A 25 ns reverse recovery time means the diode clears stored charge fast enough to avoid excessive turn-on loss in the MOSFET in a hard-switched PFC or flyback. At 100 kHz switching, each recovery event costs about 25 ns of overlap — at 200 V and 6.5 A that is roughly 32.5 µJ per cycle, or 3.25 W per diode. Compare that to a standard recovery diode (trr > 500 ns) where the loss would be 10× higher. The 6 µA reverse leakage at 200 V is tight enough for junction temperatures up to 175°C, but the leakage doubles roughly every 10°C above 25°C — budget headroom if the heatsink runs hot. ## TO-220FP full-pack — field-swap friendly The TO-220FP full-pack (isolated tab) means no insulating pad or washer needed between the tab and the heatsink — a real time-saver when you are swapping a diode on site without a lab bench. The three through-hole pins are clearly spaced, and the common-cathode pair (pins 2 and 3 tied internally, pin 1 the anode of one diode, pin 3 the anode of the other) is standard enough that a quick continuity check with a multimeter confirms orientation. No hot-air station required; just a soldering iron and a desoldering pump.","metaTitle":"ST STTH1302CFP Fast Recovery Diode, 200V 6.5A, 25ns trr","metaDescription":"STMicroelectronics STTH1302CFP fast recovery diode, 200V Vr, 6.5A per diode, 25ns trr, common cathode TO-220FP.","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":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH1302","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220FP","Reverse Recovery Time (trr)":"25 ns","Current - Reverse Leakage @ Vr":"6 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 6.5 A","Current - Average Rectified (Io) (per Diode)":"6.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/baa30516faed73259e77bb7b603bc3d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1302CFP/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1302CFP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1302CFP when reusing this data.
