A 22 ns trr at 15 A forward current means the diode clears stored charge quickly enough to keep reverse-recovery losses low in continuous-current-mode (CCM) PFC boost stages running above 100 kHz. Slower diodes in the same position would push junction temperature higher and force a larger heatsink or a lower switching frequency. Forward voltage is 1.05 V maximum at 15 A per diode, giving a conduction loss of roughly 15.75 W per diode at full rated current. The TO-247-3 package with its large copper tab is sized to pull that heat into a heatsink — expect to budget a thermal interface pad and a clamp or screw mount. ## 175°C junction — thermal headroom for tight layouts Maximum junction temperature is 175°C, which is the standard high-temperature ceiling for industrial-grade power diodes. It gives a wider derating margin in a 85°C ambient cabinet than a 150°C-rated part would, but the leakage current at 200 V reverse (20 µA at 25°C) climbs with temperature — the thermal design should keep Tj below 150°C in steady state to avoid runaway. The base product number is STTH3002, and the CW suffix denotes the TO-247-3 package variant.","metaTitle":"STTH3002CW Diode Array, 200V 15A Fast Recovery TO-247-3","metaDescription":"STTH3002CW dual common-cathode fast-recovery diode, 200V 15A per diode, 22ns trr, TO-247-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-247-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH3002","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-247-3","Reverse Recovery Time (trr)":"22 ns","Current - Reverse Leakage @ Vr":"20 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.05 V @ 15 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7500","priceTiers":[{"qty":1,"price":"$2.75000","currency":"USD"},{"qty":10,"price":"$2.28000","currency":"USD"},{"qty":100,"price":"$1.81470","currency":"USD"},{"qty":500,"price":"$1.53552","currency":"USD"},{"qty":1000,"price":"$1.30286","currency":"USD"},{"qty":2000,"price":"$1.23772","currency":"USD"},{"qty":5000,"price":"$1.19119","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/60fa1dbc456639e269b54ecda772000d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH3002CW/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH3002CW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH3002CW when reusing this data.
