The 55 ns reverse recovery time is the headline parameter: it keeps the switching energy per cycle low enough that a hard-switched converter can run without a snubber eating the efficiency gain. The TO-247-3 package handles the thermal load from both dice on a single heatsink pad. ## Forward drop and thermal headroom Forward voltage is 1.25 V max at 30 A per diode — that is the conduction loss floor for the rectifier stage. With a 175°C maximum junction temperature, the device can sustain the full 30 A in a hot ambient if the heatsink is sized correctly. The 60 µA reverse leakage at 300 V is a sanity check for the blocking state; it rises with temperature, so the thermal model should include leakage power at the hot junction.","metaTitle":"STTH6003CW 300V 30A Ultrafast Diode, 55 ns trr, TO-247-3","metaDescription":"STTH6003CW 300V 30A dual ultrafast diode in TO-247-3. 55 ns trr, 1.25 Vf at 30 A, 175°C Tj max.
