The 880 mV forward drop at 15 A keeps conduction losses manageable in output rectification stages for switch-mode power supplies, battery chargers, and DC-DC converters. The fully isolated TO-220FP tab eliminates the need for an insulating washer and thermal compound against the heatsink — a time-saver in assembly and a reliability win in high-vibration environments. ## Common-cathode pair — circuit topology fit The common-cathode configuration ties the cathodes of both diodes together internally, with the two anodes brought out as separate pins.","metaTitle":"STPS30L120CFP Schottky Rectifier","metaDescription":"STPS30L120CFP dual Schottky rectifier: 120V Vr, 15A per diode, 880mV Vf, common cathode, TO-220 Full Pack.

For a new design, look for a currently-active 120 V, 15 A dual Schottky in a TO-220 Full Pack or TO-220FP package from ST or another major manufacturer. The common-cathode configuration and fully isolated tab are the two critical selection criteria.
