The forward voltage drop is 2.95 V max at 15 A — conduction loss at full load is about 44 W, so the DO-247 tab must be bolted to a heatsink sized for the junction-to-case thermal path. Junction temperature is rated to 175°C max, which allows operation in high-ambient environments such as enclosed power supplies or motor-drive cabinets. Reverse leakage at 600 V is 20 µA — negligible at room temperature but rises with junction temperature; budget for it in the thermal design. ## DO-247-2 through-hole — mounting and thermal interface The DO-247-2 package with straight leads is a through-hole, tab-mount package. The copper tab is the cathode and the primary heat path — it must be soldered or bolted to a heatsink with a thermal interface material. The through-hole leads handle the 15 A continuous current without trace-lift risk, but the PCB pad area under the tab sets the effective RthJA.","metaTitle":"STTH15RQ06W Fast Recovery Diode, 600 V, 15 A, 50 ns trr","metaDescription":"STTH15RQ06W fast recovery diode: 600 V reverse voltage, 15 A average current, 50 ns trr.
