BAT48JFILM

STMicroelectronics · Schottky Diodes · SOD-323

BAT48JFILM from STMicroelectronics, in a SOD-323. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, marked by the band on the package; the diode blocks up to VRRM 40 V reverse and conducts up to IF 350 mA continuous forward current.
2 A passive Anode of the single Schottky diode; forward voltage drop is typically 0.4 V at IF = 10 mA and 0.75 V at IF = 200 mA (Tj = 25 °C).
