The 36 ns reverse recovery time places this diode in the fast-recovery class, well under the 500 ns threshold. In a continuous-conduction-mode PFC stage, that trr directly reduces the turn-on loss in the MOSFET and cuts EMI ringing at the switching node. Compare this to a standard recovery diode (trr in the microsecond range) where the reverse current spike adds significant dissipation and noise. The 1.1 V forward drop at 15 A is typical for a 200 V silicon fast diode — no surprise there, but the 10 µA leakage at 200 V reverse is low enough to keep standoff losses negligible at high line. ## Mounting and thermal handling with the TO-220 Full Pack The TO-220FPAC (Full Pack) package has a fully encapsulated backside — no exposed metal tab. That means the mounting screw does not need an insulating bushing or mica washer, and the case is electrically isolated. For a 15 A average current, you still need a heatsink; the junction is rated to 175 °C max, so thermal design should keep the junction below that under worst-case load and ambient. The through-hole leads suit point-to-point wiring or a PCB with drilled holes — no reflow profile needed.","metaTitle":"STTH1502FP Fast Recovery Diode, 200 V, 15 A, 36 ns trr","metaDescription":"STTH1502FP fast recovery diode: 200 V, 15 A average, 36 ns trr, TO-220 Full Pack.","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 Full Pack","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1502","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220FPAC","Reverse Recovery Time (trr)":"36 ns","Current - Reverse Leakage @ Vr":"10 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"15A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 15 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbaea564a533bd323b3e0187ee0cc37a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH1502FP?","answer":"The reverse recovery time (trr) is 36 ns, making it a fast-recovery diode suitable for high-frequency switching applications."},{"question":"Does STTH1502FP have an equivalent or replacement?","answer":"STMicroelectronics lists this part as active with no documented successor.
