60 V / 5.1 A common-cathode Schottky for automotive DC-DC and OR-ing
The V15KM60CHM3/H is a 60 V, 5.1 A average rectified current per diode Schottky diode in a 1-pair common-cathode configuration, housed in the Vishay FlatPAK (5x6) surface-mount package. It belongs to the Automotive AEC-Q101 series, qualified for -40°C to 175°C junction temperature.
Forward drop and switching speed — conduction loss and recovery
This is the conduction loss floor at that current; at the 5.1 A average rating the drop will be lower, but the 630 mV ceiling is the figure to budget for worst-case thermal design. Listed as a fast recovery type — under 500 ns, above 200 mA — which puts it in the Schottky barrier class where recovery is majority-carrier and essentially instantaneous. The real switching loss is dominated by the junction capacitance and the circuit's dV/dt, not a stored-charge reverse recovery.
