At 5 A per diode, the 530 mV Vf translates to about 2.65 W of conduction loss per leg at full load. In a TO-220 with a heatsink tab, that is a manageable thermal load — but without a heatsink the junction will climb toward the 150°C maximum quickly. The 200 µA reverse leakage at 40 V is typical for a 40 V Schottky; expect it to rise with temperature, so the thermal design needs headroom above the steady-state dissipation.","metaTitle":"STPS10L40CT Schottky Diode Array, 40V 5A TO-220-3","metaDescription":"STPS10L40CT dual common-cathode Schottky rectifier, 40V 5A per diode, 530 mV Vf, TO-220-3.
