Its 85 ns reverse recovery time (trr) places it in the fast-recovery class — built for continuous-conduction-mode (CCM) boost PFC stages and high-frequency output rectification in switched-mode power supplies, where a standard recovery diode would burn through the switching loss budget. The 85 ns trr at rated conditions means the diode recovers before the MOSFET in a boost PFC turns back on, minimising the reverse-recovery current spike that otherwise adds EMI and shoot-through stress. Forward voltage is 1.3 V maximum at 3 A — at full rated current the diode dissipates about 3.9 W. In an SMB package that means the PCB must pull heat through the solder joint and into a copper pour; a 1 oz copper pad of at least 300 mm² keeps the junction below 125 °C in still air.","metaTitle":"STTH3L06U 600V 3A Fast Recovery Diode, SMB, 85 ns trr","metaDescription":"STTH3L06U: 600 V, 3 A fast recovery rectifier in DO-214AA (SMB). 85 ns trr suits PFC and SMPS output stages.
