It is rated for a 100 V reverse voltage and 150 mA average rectified current per diode — a combination that puts it in the small-signal Schottky class but with headroom for 48 V bus clamping or 24 V industrial flyback suppression where typical 30-60 V Schottkys would be marginal. Forward voltage is 450 mV at 10 mA, keeping conduction losses low in signal-level steering or protection circuits. Reverse leakage is 5 µA at 75 V, which is acceptable for most low-power applications but worth noting if the diode sits at elevated junction temperature for extended periods — leakage doubles with every 10 °C rise above 25 °C. ## SOT-323 rework and orientation The package is marked with a cathode band on one side; under a hot-air station at 300 °C for 30 seconds the part reflows cleanly without pad lifting if the board is preheated to 100 °C.","metaTitle":"STMicro BAT46AWFILM Schottky Diode Array, 100 V, SOT-323","metaDescription":"STMicro BAT46AWFILM dual Schottky diode array, 100 V Vr, 150 mA Io, 450 mV Vf, common-anode in SOT-323.
