60 V, 7.5 A per leg — the common-cathode rectifier choice
The STPS15L60CB is a dual Schottky rectifier from STMicroelectronics, housing two 7.5 A diodes in a common-cathode configuration within a single DPAK package. The 60 V reverse voltage rating and 620 mV forward drop at 7.5 A set the conduction loss floor for the pair.
Forward drop and leakage — the thermal budget drivers
At 7.5 A per diode, the maximum forward voltage is 620 mV — the dominant term in the conduction loss calculation.
DPAK footprint and surface-mount assembly
The TO-252-3 (DPAK) package has a single exposed tab that carries the common-cathode connection.
