The STPS41L60CG is a dual Schottky rectifier from STMicroelectronics, configured as a 1-pair common cathode in a single D2PAK (TO-263AB) surface-mount package. The 600 µA reverse leakage at 60 V is typical for a 20 A Schottky in this voltage class. The fast recovery characteristic (≤ 500 ns, > 200 mA) qualifies it for switching power supply output rectification and OR-ing applications in the 48 V to 60 V bus range.
Obsolete — planning the BOM line
STMicroelectronics no longer manufactures this specific order code. Any alternate must be qualified against the 60 V / 20 A per-diode rating and the D2PAK footprint.
That tab is the common cathode connection and the primary heat path. The PCB layout needs a thermal pad and via array under the tab to keep the junction temperature below the 150 °C maximum. The tube shipping medium is standard for this package variant.
