Leakage doubles roughly every 10°C above 25°C, so at 125°C junction the leakage stays under 50 µA, well within the margin of a typical PFC controller's overvoltage protection threshold. Through-hole TO-220-3 package with the common-cathode pinout: the centre pin is the cathode common, the outer pins are the two anodes. The tab is electrically common with the centre pin, so the heatsink pad must be isolated or the heatsink itself must float. The 0.100-inch pitch is standard for TO-220 footprints. ROHS3 compliant.","metaTitle":"STTH602CT Fast Recovery Diode, 200V 3A, 30ns trr, TO-220","metaDescription":"STTH602CT dual common-cathode fast recovery diode, 200V Vr, 3A per diode, 30ns trr, TO-220 package.
