The back tab is electrically isolated from the die, so the part can be bolted directly to a heatsink without a mica washer or thermal pad — one fewer assembly step and a lower thermal resistance junction-to-case. The 175 °C junction rating lets it run hot in a cramped PSU or an engine-bay converter without derating the 7.5 A average current per diode. ## Common-cathode pair — one part replaces two discretes The 1-pair common-cathode configuration means the two anodes are independent and the cathodes are tied internally. That matches the topology of a center-tapped secondary rectifier or a two-diode boost PFC where the cathodes share the output rail. Using the STTH15AC06CFP saves the board space of two separate TO-220 diodes and cuts the pick-and-place count in half.","metaTitle":"ST STTH15AC06CFP Fast Recovery Diode Array, 600V 7.5A","metaDescription":"ST STTH15AC06CFP dual common-cathode fast recovery diode, 600V 7.5A per diode, 50ns trr, TO-220FPAB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH15","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220FPAB","Reverse Recovery Time (trr)":"50 ns","Current - Reverse Leakage @ Vr":"1 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Operating Temperature - Junction":"-65°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.9 V @ 7.5 A","Current - Average Rectified (Io) (per Diode)":"7.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2900","priceTiers":[{"qty":1,"price":"$1.36000","currency":"USD"},{"qty":10,"price":"$1.22000","currency":"USD"},{"qty":100,"price":"$0.95090","currency":"USD"},{"qty":500,"price":"$0.78556","currency":"USD"},{"qty":1000,"price":"$0.67620","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/661ee416bf70e0c44dc0675ba3e186a3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH15AC06CFP/alternatives.json"},"ai":{"faq":[{"question":"Is the STTH15AC06CFP obsolete and what is the replacement?","answer":"Yes, ST has marked the STTH15AC06CFP as obsolete.
