BAT54WS-7-F

Diodes Incorporated · Schottky diode, small signal · SOD-323

Diodes Incorporated single 30 V, 200 mA small-signal Schottky diode in SOD-323 (marking L9). Fast switching with a low forward voltage: detectors, clamps and reverse-polarity protection.

Verification

A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.

File What it is
bat54ws-7-f.kicad_sym KiCad symbol, with MPN, manufacturer and distributor numbers as properties
bat54ws-7-f.kicad_mod KiCad footprint: Diode_SMD:D_SOD-323, KiCad official, CC-BY-SA 4.0
bat54ws-7-f.step / bat54ws-7-f.glb 3D model, Z-up, seated on z = 0: KiCad packages3D (tag 10.0.6), D_SOD-323.step
bat54ws-7-f-etched.step / bat54ws-7-f-etched.glb The same model with the part number laser-etched on top as a separate, toggleable Adom.LaserEtch group (a virtual identification aid, not the maker's real marking)
bat54ws-7-f.lbr Fusion 360 / EAGLE library: one deviceset, each with its own MPN, manufacturer and LCSC / Mouser / DigiKey attributes
altium/Adom_bat54ws_7_f.SchLib / .PcbLib Altium library pair (adom-lbr, no Altium needed): symbol and footprint with the 3D body, parameters carry the part numbers; altium/*.adom-lbr.json is the canonical hub each was built from
