Packaged in a TO-220-3 through-hole case, it is a standard choice for high-current OR-ing, output rectification in switch-mode supplies, and freewheeling diode networks where the common-cathode pair shares a single heatsink tab. ## Forward voltage and reverse leakage — the thermal budget drivers At 10 A forward current the maximum forward voltage is 570 mV — the power dissipation per diode is roughly 5.7 W at full load, so the TO-220 tab must be heatsunk to keep junction temperature below the 175 °C absolute maximum. Reverse leakage is specified at 100 µA at 45 V, a figure that rises with temperature; the designer should derate the reverse voltage margin in high-ambient enclosures.","metaTitle":"STPS2045CT Schottky Diode Array, 45V, 10A per Diode, TO-220","metaDescription":"STPS2045CT dual common-cathode Schottky rectifier: 45V Vrrm, 10A per diode, 570mV Vf at 10A.
