The 20 µA reverse leakage at 300 V is a room-temperature figure; leakage doubles every 10°C above 25°C, so at 125°C junction the standing loss from leakage alone approaches 0.5 W. ## Active status, no LTB clock ROHS3 compliant per.","metaTitle":"STTH30R03CG-TR 300V 15A Fast Recovery Diode, 35 ns trr","metaDescription":"STTH30R03CG-TR dual common-cathode fast recovery diode: 300 V, 15 A per diode, 35 ns trr, D2PAK surface mount.
