This saves PCB area and assembly cost versus two separate TO-220 devices, but the common cathode means the pair cannot be used as independent rectifiers — they share the output rail in a center-tap or boost-stage configuration. ## Reverse leakage at temperature Reverse leakage is specified at 500 µA at 45 V. Schottky leakage doubles with every 10–15°C rise above 25°C, so at 125°C junction the leakage current can dominate the thermal budget in light-load or standby conditions. The 175°C maximum junction rating gives headroom for high-surge environments, but the designer should derate the reverse voltage in continuous high-temperature operation.","metaTitle":"STPS6045CW Schottky Diode Array, 45V 30A TO-247-3, Active","metaDescription":"STPS6045CW dual common-cathode Schottky rectifier: 45V Vr, 30A per diode, 630mV Vf at 30A.
