Its 40 ns reverse recovery time and 1.25 V forward voltage at 10 A make it a fit for continuous-conduction-mode PFC boost stages, output rectification in switched-mode supplies, and freewheeling diodes in motor-drive snubbers. The 40 ns reverse recovery time keeps the stored charge low during commutation, which reduces turn-off losses and ringing in hard-switched topologies. The 20 µA reverse leakage at 300 V holds the off-state power dissipation to milliwatts at the bus voltage. ## 175°C junction — thermal headroom for tight enclosures The D²PAK's exposed tab conducts heat to the PCB copper pour — the board's thermal resistance, not the die, sets the real current limit in continuous operation.","metaTitle":"STTH2003CGY-TR 300V 10A Fast Recovery Diode, D2PAK, 40ns trr","metaDescription":"STTH2003CGY-TR: STMicroelectronics 300V 10A dual common-cathode fast recovery diode in D2PAK. 40 ns trr, 175°C Tj.
