The STPS30L60CTN is a dual Schottky rectifier from STMicroelectronics, housing a 1 Pair Common Cathode configuration in a single TO-220-3 package. The 60 V reverse voltage ceiling and 480 µA leakage at that voltage set the safe operating area for 48 V bus and 12 V–24 V output rectification in switch-mode power supplies.
600 mV forward drop at 15 A — thermal budget anchor
Forward voltage (Vf) is specified at 600 mV maximum at 15 A per diode. At full load each diode dissipates 9 W; with both diodes conducting, total junction loss hits 18 W before switching losses. The 150°C maximum junction temperature leaves limited headroom in a TO-220AB narrow-lead package — a heatsink with good airflow is mandatory above 5 A per diode continuous.

TO-220AB narrow-leads — footprint watch
The supplier device package is TO-220AB Narrow Leads, which differs from the standard TO-220 footprint. The lead spacing is tighter, so a standard TO-220 PCB layout may not fit without lead forming or board modification.
