The 900 mV forward drop at 100 mA is typical for a small-signal Schottky; at the full 300 mA average current the drop will be higher, so check the power dissipation against the SOT-323 thermal impedance if you push it near the limit. The 1 µA reverse leakage at 30 V is tight enough for a battery-monitoring circuit where every microamp matters. SOT-323 (SC-70) three-lead package. Surface-mount only. Reel or cut-tape options — the cut tape is fine for a prototype run; the reel is what the pick-and-place line wants for volume. ROHS3 compliant and ECOPACK®2 — the package is halogen-free and the plating is matte tin. No PCN risk on the near horizon.","metaTitle":"BAT54SWFILMY Schottky Diode Array, 40V, 300mA, AEC-Q101","metaDescription":"Automotive-grade Schottky diode array, 40V reverse voltage, 300mA average rectified current, 5ns reverse recovery time.
