The 200 V reverse rating gives headroom for 48 V to 100 V bus rails, including the flyback voltage spikes in an off-line PFC or LLC converter output stage. ## 175°C junction — the thermal budget that matters The 175°C Tj max means you can push the diode harder on current without derating as aggressively as a 150°C-rated Schottky, but the reverse leakage at 200 V and high temperature (15 µA at 25°C) will climb exponentially — budget the leakage power in the thermal stack-up.","metaTitle":"STPS20200CT Schottky Diode, 200 V 20 A Dual Common Cathode","metaDescription":"STPS20200CT dual Schottky diode: 200 V reverse, 10 A per diode, 860 mV Vf at 10 A, 175°C Tj max.
