The 1.45 V forward voltage at 50 A is a conduction-loss trade-off against that speed — expect to size the heatsink for the sum of switching and conduction dissipation, especially at high line. ## 175 °C junction — thermal headroom for dense layouts Rated for a maximum junction temperature of 175 °C, the STTH100W06CW gives you margin in designs where the rectifier sits near hot magnetics or in a confined airflow path. The 20 µA reverse leakage at 600 V is a room-temperature typical; expect it to climb with junction temperature, so derate the reverse voltage margin if the diode runs continuously near Tj max. The TO-247-3 package takes a standard screw-mount or clip heatsink — the tab is the common cathode, so insulating hardware is needed if multiple devices share a heatsink. Listed with an active product status. This is not a last-time-buy or NRND part — ST continues to manufacture it, which means the supply channel is the normal distribution pipeline. No successor part number has been issued because none is needed.","metaTitle":"STTH100W06CW fast-recovery diode, 600 V 50 A, 75 ns trr","metaDescription":"ST STTH100W06CW standard fast-recovery diode, 600 V, 50 A per diode, 75 ns trr, TO-247-3.
