Each diode is rated for 100 V reverse voltage and 150 mA average rectified current. The low forward voltage of 450 mV at 10 mA makes it well suited for low-loss OR-ing, flyback clamping, and protection circuits in battery-powered or low-voltage rail designs. The 100 V reverse voltage rating exceeds the typical small-signal Schottky. The 5 µA leakage at 75 V reverse bias is a standard figure for this voltage class. ## Common-anode pair — application note The common-anode pinout ties both cathodes to separate pins, with the shared anode on the third pin. This is the standard configuration for dual Schottky OR-ing: each cathode connects to a separate power source, and the common anode feeds the load. The SOT-23-3 footprint matches the standard small-signal layout; no board respin needed if swapping from a single Schottky in the same package. This part is listed as Active on the manufacturer's lifecycle status and ROHS3 compliant. There is no NRND or EOL notice, so it remains a current-production choice for new designs.","metaTitle":"STMicroelectronics BAR46AFILM Schottky Diode Array, 100 V","metaDescription":"BAR46AFILM Schottky diode array, 100 V reverse voltage, 150 mA per diode, common anode pair in SOT-23-3.
